[0039] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0040] In the rapid development of NGSO satellites, the protection strategy for GSO satellite communications is a crucial issue that NGSO satellites must address. NGSO satellites must adopt practical and feasible interference avoidance strategies to ensure the safe use of GSO satellite frequencies.

[0041] In related technologies, to avoid interference between low-Earth orbit (LEO) NGSO and high-Earth orbit (GEO) satellite systems in scenarios where both systems coexist, various interference avoidance techniques have been proposed. These include calculating the avoidance area by comparing the I / N value in each latitude / longitude grid with its threshold value, encoding the generated latitude / longitude grid information to form an interference avoidance information file for storage, and verifying its effectiveness using on-orbit verification methods. However, since the interference avoidance area for NGSO satellites is closely related to their position, and NGSO satellites are constantly in high-speed motion, the interference avoidance command packets for NGSO satellites typically contain a large amount of avoidance information. This not only requires significant satellite-to-ground link transmission resources but also poses a substantial challenge to the storage space of the satellite payload.

[0042] Furthermore, the large size of the interference avoidance command packets from NGSO satellites can impact the performance and real-time response capabilities of the communication system. Specifically, large command packets lead to increased data transmission latency, especially under conditions of high network latency or limited bandwidth. Simultaneously, larger command packets result in excessive redundancy during data transmission, increasing processing complexity and potentially triggering communication overhead such as retransmissions, thereby further affecting the overall efficiency and throughput of the communication system.

[0043] To address the aforementioned issues, this application proposes a method, apparatus, and communication device for determining interference avoidance instructions. By determining the beam directivity of the target satellite within at least one ground grid covered by the target satellite's communication coverage, based on the center position of the target satellite's communication coverage and the target's longitude range, interference can be effectively avoided. By compressing the interference avoidance instructions for ground grids where the beam directivity is not pointingable, the content of the target satellite's interference avoidance instructions can be significantly reduced, thereby reducing storage space requirements, reducing instruction transmission costs, and improving the efficiency of instruction decoding and execution.

[0044] The following description, with reference to the accompanying drawings, outlines a method, apparatus, and communication device for determining interference avoidance instructions according to embodiments of this application.

[0045] Figure 1 This is a flowchart illustrating a method for determining the content of an interference avoidance instruction provided in an embodiment of this application.

[0046] like Figure 1 As shown, the method for determining the content of the interference avoidance instruction includes the following steps:

[0047] Step 101: Determine multiple ground grids covered by the target satellite's communication based on the target satellite's location.

[0048] The target satellite can be a medium-Earth orbit satellite or a low-Earth orbit satellite, and the target satellite can be uniform or non-uniform, with arbitrary inclination angle.

[0049] In some embodiments, the target satellite can be any NGSO satellite. An NGSO satellite is a satellite in a satellite orbit other than a GSO satellite.

[0050] The target satellite's position is its three-dimensional position at a given moment. This three-dimensional position can be the target satellite's coordinates in ECI (Earth-Centered Inertial) or in ECEF (Earth-Centered, Earth-Fixed).

[0051] In some embodiments, the Earth's surface can be pre-divided into multiple ground grids to facilitate efficient management of geographical regions on the Earth's surface. The ground grid division can be based on latitude and longitude, geocentric angle, uniform grid points, or regional division; there are no limitations on this.

[0052] It should be noted that once the grid is generated, it will remain unchanged thereafter.

[0053] In some embodiments, the Earth's surface can be pre-divided into grids according to ground grid division rules. These rules can be based on equal latitude and longitude, for example, dividing the Earth's surface into grids at fixed latitude and longitude intervals (e.g., Δλ=1°, Δφ=1°, where λ represents longitude and φ represents latitude). Alternatively, the rules can be based on variable resolution, for example, adjusting the grid density according to regional importance (e.g., Δλ=0.1° for urban areas, Δλ=1° for remote areas, where λ represents longitude).

[0054] In some embodiments, to facilitate the differentiation of different ground grids, a unique code can be assigned to each ground grid, and the corresponding ground grid can be identified by the code.

[0055] In some embodiments, multiple ground grids covering the target satellite's communication coverage can be determined from a pre-divided ground grid based on the target satellite's location.

[0056] Step 102: Determine the beam directivity of the target satellite within the corresponding ground grid based on the position of the target satellite, the center position of at least one ground grid, and the target longitude range.

[0057] The target longitude range is the longitude range of at least one geostationary satellite orbit (GSO) that needs to be avoided by the ground grid.

[0058] GSO longitude refers to the longitude of a GSO satellite in its circular orbit, specifically its position relative to the prime meridian.

[0059] GSO satellites operate in a fixed circular orbit approximately 36,000 kilometers (or 35,786 kilometers, the exact figure may vary slightly depending on the source) above the Earth's equator. The orbital period of a GSO satellite is the same as the Earth's rotation period, therefore, relative to any reference point on Earth, a GSO satellite appears stationary. The latitude of a GSO satellite is fixed at 0°, and its longitude uniquely determines its position within its circular orbit.

[0060] In some embodiments, after obtaining the ground grid covered by the target satellite communication, the target longitude range can be determined based on the center position of at least one ground grid covered by the target satellite communication, that is, the GSO longitude range to be avoided in at least one ground grid can be determined. Then, the beam directivity of the target satellite in the corresponding ground grid can be determined based on the position of the target satellite, the center position of at least one ground grid and the target longitude range.

[0061] Among them, the beam directivity of the target satellite within the corresponding ground grid is used to indicate whether the target satellite can communicate normally within the corresponding ground grid.

[0062] In some embodiments, if the beam directionality of the target satellite in the corresponding ground grid is in a pointable state, it means that the target satellite can communicate normally in the corresponding ground grid; if the beam directionality of the target satellite in the corresponding ground grid is in a non-pointable state, it means that the target satellite cannot communicate normally in the corresponding ground grid.

[0063] It should be noted that the target longitude range is the longitude range of at least one geostationary satellite orbit (GSO) to be evaded on a ground grid. Determining the target longitude range is equivalent to determining the position of at least one GSO satellite to be evaded on a ground grid. Therefore, based on the position of the target satellite, the center position of any ground grid, and the target longitude range, the beam directivity of the target satellite within that ground grid can be determined.

[0064] In some embodiments, if it is determined, based on the position of the target satellite, the center position of any ground grid, and the target longitude range, that the target satellite interferes with the communication of the GSO satellite to be avoided in the ground grid, then the beam directivity of the target satellite within the ground grid is determined to be unpointable; if it is determined, based on the position of the target satellite, the center position of any ground grid, and the target longitude corresponding to the ground grid, that the target satellite will not interfere with the communication of the GSO satellite to be avoided in the ground grid, then the beam directivity of the target satellite within the ground grid is determined to be pointable.

[0065] Step 103: Compress the interference avoidance instructions for the ground grid where the beam directionality is not pointing to obtain the interference avoidance instructions for the target satellite.

[0066] In related technologies, interference avoidance commands containing a large amount of avoidance information are generated for the interference avoidance zone of NGSO (the area where NGSO satellite communication on the ground interferes with GSO satellite communication on the ground). For example, all area information of the NGSO interference avoidance zone is included in the interference avoidance command. This not only consumes a large amount of satellite-to-ground link transmission resources, but also poses a significant challenge to the storage space of the satellite payload. However, in the embodiments of this application, by compressing the interference avoidance commands for ground grids where the beam pointing is not pointingable, the content of the interference avoidance commands for the target satellite can be significantly reduced, thereby reducing storage space requirements, reducing command transmission costs, and improving the efficiency of command decoding and execution.

[0067] In some embodiments, after determining the beam directivity of the target satellite within at least one ground grid in a plurality of ground grids covering its communication coverage, the interference avoidance area of ​​the target satellite can be determined based on the ground grids whose beam directivity is unpointable. Then, when generating interference avoidance instructions for the interference avoidance area of ​​the target satellite, the generated interference avoidance instructions are compressed to reduce the content of the interference avoidance instructions for the target satellite.

[0068] In some embodiments, when generating interference avoidance instructions for the interference avoidance area of ​​a target satellite, a portion of the area information that can identify the range of the interference avoidance area can be selected from all the area information of the interference avoidance area of ​​the target satellite, and the interference avoidance instructions for the interference avoidance area can be generated based on this portion of the area information, thereby reducing the content of the interference avoidance instructions for the target satellite.

[0069] In this embodiment, multiple ground grids covering the target satellite's communication area are determined based on the target satellite's location. The beam directivity of the target satellite within the corresponding ground grid is determined based on the center position of at least one ground grid and the target longitude range, where the target longitude range is the geostationary orbit (GSO) longitude range of the at least one ground grid to be avoided. Interference avoidance instructions for ground grids with unpointable beam directivity are compressed to obtain the interference avoidance instructions for the target satellite. Therefore, by determining the beam directivity of the target satellite within at least one ground grid covered by its communication area based on the center position and target longitude range, effective interference avoidance can be ensured. Furthermore, by compressing the interference avoidance instructions for ground grids with unpointable beam directivity, the content of the interference avoidance instructions for the target satellite can be significantly reduced, thereby reducing storage space requirements, decreasing instruction transmission costs, and improving the efficiency of instruction decoding and execution.

[0070] Figure 2 This is a flowchart illustrating another method for determining the content of interference avoidance instructions provided in an embodiment of this application.

[0071] like Figure 2 As shown, the method for determining the content of the interference avoidance instruction may include the following steps:

[0072] Step 201: Determine multiple ground grids covered by the target satellite's communication based on the target satellite's location.

[0073] Step 202: Determine the beam directivity of the target satellite within the corresponding ground grid based on the position of the target satellite, the center position of at least one ground grid, and the target longitude range.

[0074] It should be noted that the explanations of steps 201 and 202 can be found in the relevant descriptions in any embodiment of this application, and will not be repeated here.

[0075] Step 203: Generate a beam pointing image corresponding to the target satellite based on the beam pointing of the target satellite within the corresponding ground grid.

[0076] Among them, the beam pointing image uses pixels to indicate the beam pointing of the target satellite within the corresponding ground grid.

[0077] In some embodiments, one pixel in the beam pointing image corresponds to one ground grid, thereby allowing different colored pixels in the beam pointing image to indicate the beam pointing of a target satellite in the corresponding ground grid.

[0078] As an example, beam pointing images can be as follows: Figure 3 As shown, the horizontal axis represents longitude and the vertical axis represents latitude. In the figure, the lighter-colored pixels indicate that the beam pointing of the target satellite in the corresponding ground grid is in a pointable state, while the darker-colored pixels indicate that the beam pointing of the target satellite in the corresponding ground grid is in a non-pointable state.

[0079] Step 204: Based on the pixels in the beam pointing image where the beam pointing is in an unpointable state, determine the latitude zone of the interference avoidance area for the target satellite, wherein the latitude value of any interference avoidance area latitude zone is the same.

[0080] In some embodiments, a region consisting of multiple pixels in the beam pointing image corresponding to the target satellite where the beam pointing is not pointing and the latitude values ​​are the same can be defined as an interference avoidance region latitude zone of the target satellite.

[0081] As an example, for Figure 3 The beam pointing image shown can determine, for example, the beam pointing pattern. Figure 4The diagram shows multiple interference avoidance region latitude bands enclosed by boxes. Each interference avoidance region latitude band is a segment composed of multiple pixels with darker colors (beam pointing is not pointing) and the same vertical coordinate (same latitude value). Furthermore, there may be multiple interference avoidance region latitude bands with the same latitude value due to different starting longitudes (e.g., ...). Figure 4 In the middle, looking from top to bottom, the first row with boxes contains two interference avoidance zone latitude bands. These two interference avoidance zone latitude bands have different starting and ending longitudes.

[0082] Step 205: Based on the latitude zone of the target satellite's interference avoidance area, the command is compressed using the target method to obtain the interference avoidance command content of the target satellite.

[0083] The target mode is used to indicate which interference avoidance latitude zones in the target satellite's interference avoidance area generate interference avoidance commands, and to indicate which avoidance information is used to identify the range of the corresponding interference avoidance area latitude zone in the generated interference avoidance commands.

[0084] In some embodiments, the target method includes: latitude zone method, symmetrical latitude zone method, interference avoidance region envelope method, and symmetrical interference avoidance region envelope method.

[0085] In both the latitude band method and the interference avoidance region envelope method, interference avoidance commands will be generated in all interference avoidance region latitude bands within the target satellite's interference avoidance region latitude band.

[0086] Among them, in the symmetrical latitude band mode and the symmetrical interference avoidance region envelope mode, interference avoidance commands are generated in the symmetrical half of the interference avoidance region latitude band of the target satellite.

[0087] In the latitude band method and the symmetrical latitude band method, the generated interference avoidance command uses the following avoidance information to identify the range of the latitude band corresponding to the interference avoidance area:

[0088] Latitude identifiers used to identify the latitude zones of interference avoidance areas;

[0089] Starting longitude identifier used to identify the starting longitude information of the latitude zone of the interference avoidance area;

[0090] Termination longitude identifier used to identify the termination longitude information of the latitude zone of the interference avoidance area.

[0091] Among them, under the interference avoidance region envelope method and the symmetrical interference avoidance region envelope method, the generated interference avoidance command uses the following avoidance information to identify the range of the latitude zone of the corresponding interference avoidance region:

[0092] Latitude identifiers used to identify the latitude zones of interference avoidance areas;

[0093] Longitude identifiers used to identify the envelope information of the latitude zone of the interference avoidance area.

[0094] As an example, for Figure 3 The beam pointing images shown are as follows: Figure 5(a) shows the interference avoidance region latitude band when the command compression is performed using the latitude band method; Figure 5(b) shows the interference avoidance region latitude band when the command compression is performed using the symmetrical latitude band method; Figure 5(c) shows the interference avoidance region envelope method when the command compression is performed using the interference avoidance region envelope method; and Figure 5(d) shows the interference avoidance region latitude band when the command compression is performed using the symmetrical interference avoidance region envelope method.

[0095] In Figure 5(a), the longitude value of the black pixel is used to identify the starting longitude information of the latitude band of the corresponding interference avoidance area, or to identify the ending longitude information of the latitude band of the corresponding interference avoidance area. In Figure 5(b), the longitude value of the bold pixel is used to identify the starting longitude information of the latitude band of the corresponding interference avoidance area, or to identify the ending longitude information of the latitude band of the corresponding interference avoidance area.

[0096] In Figures 5(c) and 5(d), the longitude values ​​of the bolded pixels are used to identify the overall envelope information of the latitude zone of the interference avoidance area.

[0097] It should be noted that the bolded pixels in Figures 5(c) and 5(d) are merely examples. In some embodiments, as shown in Figures 5(c) and 5(d), the longitude values ​​of the boundary pixels of the overall region consisting of multiple interference avoidance region latitude bands that need to generate interference avoidance instructions can be used to identify the range of these interference avoidance region latitudes. Alternatively, for each interference avoidance region latitude band that needs to generate interference avoidance instructions, the longitude values ​​of the boundary pixels of that interference avoidance region latitude band can be used to identify the range of that interference avoidance region latitude band.

[0098] In some embodiments, the target interference avoidance region latitude band matching the target mode can be determined first from the target satellite's interference avoidance region latitude band. For example, if the target mode is a latitude band mode or an interference avoidance region envelope mode, then the target satellite's interference avoidance region latitude band is determined as the target interference avoidance region latitude band; if the target mode is a symmetrical latitude band mode or a symmetrical interference avoidance region envelope mode, then the interference avoidance region latitude band on either side of the target satellite's symmetrical interference avoidance region latitude band is determined as the target interference avoidance region latitude band. Then, based on the identification information of the target interference avoidance region latitude band, the instruction content of the target interference avoidance region latitude band is determined. The identification information of the target interference avoidance region latitude band is used to identify the target interference avoidance region latitude band and the regional information used to identify the target interference avoidance region latitude band. Finally, based on the instruction content of the target interference avoidance region latitude band, the interference avoidance instruction content of the target satellite is determined. The interference avoidance instruction content of the target satellite includes at least the instruction content of the target interference avoidance region latitude band.

[0099] In some embodiments, the latitude zone of the interference avoidance area of ​​the target satellite can be determined as the latitude zone of the target interference avoidance area; or, the latitude zone of the interference avoidance area on either side of the symmetrical latitude zone of the target satellite can be determined as the latitude zone of the target interference avoidance area.

[0100] It should be noted that the choice between the two methods mentioned above is based on the objective method.

[0101] In some embodiments, the instruction content of the target interference avoidance area latitude zone can be determined based on the unique identifier of the target interference avoidance area latitude zone and the area address identifier, wherein the area address identifier is used to indicate the area information of the target interference avoidance area latitude zone.

[0102] In some embodiments, the area address identifier may include a latitude identifier for indicating the latitude information of the target interference avoidance area latitude zone, a starting longitude identifier for indicating the starting longitude information of the target interference avoidance area latitude zone, and a ending longitude identifier for indicating the ending longitude information of the target interference avoidance area latitude zone; or, the area address identifier may include a latitude identifier for indicating the latitude information of the target interference avoidance area latitude zone and a latitude and longitude identifier for indicating the envelope information of the target interference avoidance area latitude zone.

[0103] In some embodiments, since the target satellite is moving at high speed, its position is different at different times. In order to facilitate the distinction of when the interference avoidance instruction of the target satellite is issued, the interference avoidance instruction of the target satellite may include the instruction content of the latitude zone of the target interference avoidance area and the time information of the target satellite's current position.

[0104] In some embodiments, the interference avoidance instruction content of the target satellite may include not only the interference avoidance instruction content of the target satellite, but also some additional information, such as the number of latitude zones of the target interference avoidance area.

[0105] In some embodiments, the position of the target satellite is the position of the target satellite at the target time. The interference avoidance instruction content of the target satellite can be determined based on the instruction content of the latitude zone of the target interference avoidance area, the number of latitude zones of the target interference avoidance area, and the start time of the interference avoidance instruction content. The start time of the interference avoidance instruction content is determined based on the target time.

[0106] As an example, if the target mode is a latitudinal band mode or a symmetrical latitudinal band mode, the interference avoidance instructions for the target satellite can be as shown in Table 1:

[0107] Table 1 Example 1 of Interference Avoidance Instructions for Target Satellites

[0108]

[0109] In this embodiment, a beam pointing image corresponding to the target satellite is generated based on the beam pointing of the target satellite within the corresponding ground grid. The beam pointing image uses pixels to indicate the beam pointing of the target satellite within the corresponding ground grid. Based on pixels in the beam pointing image where the beam pointing is not pointingable, the latitude band of the interference avoidance region for the target satellite is determined, where the latitude value of any interference avoidance region latitude band is the same. Based on the latitude band of the interference avoidance region for the target satellite, command compression is performed using a target-oriented method to obtain the interference avoidance command content for the target satellite. Therefore, by determining the latitude band of the target satellite's interference avoidance region through the beam pointing image corresponding to the target satellite, and then performing command compression using a target-oriented method for the interference avoidance region latitude band, the interference avoidance command content of the target satellite can be significantly reduced, thereby reducing storage space requirements, reducing command transmission costs, and improving the efficiency of command decoding and execution.

[0110] Figure 6 This is a flowchart illustrating another method for determining the content of interference avoidance instructions provided in an embodiment of this application.

[0111] like Figure 6 As shown, the method for determining the content of the interference avoidance instruction may include the following steps:

[0112] Step 601: Determine multiple ground grids covered by the target satellite's communication based on the target satellite's location.

[0113] Step 602: Based on the center position of at least one ground grid, determine the first ground grid with the largest latitude value and the second ground grid with the smallest latitude value from at least one ground grid.

[0114] In some embodiments, the center position of each ground grid has a corresponding longitude and latitude value, so that after obtaining the ground grid covered by the target satellite communication, the two ground grids with the largest and smallest latitude values ​​can be determined from the center position of at least one ground grid among the multiple ground grids covered by the target satellite communication.

[0115] Step 603: Determine the target longitude range based on the first longitude range corresponding to the first ground grid and the second longitude range corresponding to the second ground grid.

[0116] The explanation of the target longitude range can be found in the relevant description in any embodiment of this application, and will not be repeated here.

[0117] The first longitude range is the farthest GSO longitude range visible to the first device located at the center of the first ground grid at the lowest operating elevation angle, and the second longitude range is the farthest GSO longitude range visible to the second device located at the center of the second ground grid at the lowest operating elevation angle.

[0118] In some embodiments, after determining the first ground grid and the second ground grid, a first longitude range corresponding to the first ground grid can be determined based on the center position of the first ground grid, that is, the farthest GSO longitude of the first device located at the center position of the first ground grid at the lowest operating elevation angle can be determined. Similarly, a first longitude range corresponding to the second ground grid can be determined based on the center position of the second ground grid, that is, the farthest GSO longitude of the second device located at the center position of the second ground grid at the lowest operating elevation angle can be determined. After that, a target longitude range can be determined based on the first longitude range and the second longitude range.

[0119] In some embodiments, the union between the first longitude range and the second longitude range can be determined as the target longitude range. For example, if the first longitude range is 0° to 40° and the second longitude range is 30° to 60°, then the target longitude range can be determined to be 0° to 60°.

[0120] The union of the first and second longitude ranges may be discontinuous. For example, if the first longitude range is 0° to 20° and the second longitude range is 40° to 60°, then the union of the first and second longitude ranges is 0° to 20° and 40° to 60°. In this case, the maximum and minimum longitude values ​​can be determined based on the first and second longitude ranges, and the longitude range from the minimum longitude value to the maximum longitude value can be determined as the target longitude range. That is, in some embodiments, the maximum and minimum longitude values ​​can be determined based on the first and second longitude ranges, and the longitude range from the minimum longitude value to the maximum longitude value can be determined as the target longitude range.

[0121] As an example, assuming the first longitude range is 0° to 20° and the second longitude range is 40° to 60°, the maximum longitude value can be determined to be 60° and the minimum longitude value to be 0°, thus the target longitude range can be determined to be 0° to 60°.

[0122] Step 604: For any target ground grid, determine at least one included angle corresponding to the target ground grid based on the position of the target satellite, the center position of the target ground grid, and the longitude range of the target.

[0123] The target longitude range is the range of longitudes from the minimum longitude value to the maximum longitude value. The minimum longitude value is the minimum longitude value in the first longitude range and the second longitude range, and the maximum longitude value is the maximum longitude value in the first longitude range and the second longitude range.

[0124] Wherein, at least one included angle is the included angle between the first connecting line and at least one second connecting line, the first connecting line is the line connecting the center position of the target ground grid and the position of the target satellite, the at least one second connecting line is the line connecting the center position of the target ground grid and the position of the satellite at at least one candidate longitude, and the at least one candidate longitude is determined based on the target longitude range.

[0125] In some embodiments, for any target ground grid, at least one loop can be performed based on the position of the target satellite, the center position of the target ground grid, and the target longitude range. In each loop, the included angle of the target ground grid in the current loop is determined based on the position of the target satellite, the center position of the target ground grid, and the candidate longitude of the target ground grid in the current loop. The candidate longitude of the target ground grid in the first loop is a first boundary value of the target longitude range, and the included angle of the target ground grid in the current loop is the angle between a first connecting line and a second connecting line of the target ground grid in the current loop. The second connecting line of the target ground grid in the current loop is the line connecting the center position of the target ground grid and the position of the satellite at the candidate longitude of the target ground grid in the current loop. Based on the included angle or the candidate longitude of the target ground grid in the current loop, it is determined whether to stop the loop. If the loop is not stopped, the candidate longitude of the target ground grid in the current loop is updated according to a set step size to obtain the candidate longitude of the target ground grid in the next loop. The included angle of the target ground grid in each loop is determined as at least one included angle corresponding to the target ground grid.

[0126] In some embodiments, the loop may be stopped if the included angle of the target ground grid in the current cycle is less than a set threshold value; or, the loop may be stopped if the candidate longitude of the target ground grid in the current cycle is equal to a second boundary value of the target longitude range, wherein the second boundary value is a boundary value different from the first boundary value.

[0127] The set threshold value can be a preset isolation angle threshold value according to relevant protocols to measure whether the target satellite will affect the GSO satellite. If the included angle of the target ground grid in this cycle is less than the set threshold value, it means that the target satellite is interfering with the communication of the satellite (GSO satellite) at the candidate longitude of the target ground grid in this cycle. At this time, the cycle can be stopped, and it can be determined that the beam pointing of the target satellite in the target ground grid is unpointable.

[0128] The first boundary value can be either the starting boundary value or the ending boundary value of the target longitude range. If the first boundary value is the starting boundary value of the target longitude range, then the second boundary value is the ending boundary value of the target longitude range. In this case, when updating the candidate longitude according to the set step size, the candidate longitude can be gradually increased according to the set step size. If the first boundary value is the ending boundary value of the target longitude range, then the second boundary value is the starting boundary value of the target longitude range. In this case, when updating the candidate longitude according to the set step size, the candidate longitude can be gradually decreased according to the set step size.

[0129] Step 605: Determine the beam directivity of the target satellite within the target ground grid based on at least one included angle corresponding to the target ground grid.

[0130] In some embodiments, if at least one included angle corresponding to the target ground grid is not less than a set threshold value, the beam pointing of the target satellite within the target ground grid is determined to be in a pointable state; or, if at least one included angle corresponding to the target ground grid is less than a set threshold value, the beam pointing of the target satellite within the target ground grid is determined to be in a non-pointable state.

[0131] The explanation of setting the threshold value is given in step 602 and will not be repeated here.

[0132] In some embodiments, a beam matrix can be used to indicate the beam directionality of a target satellite within a corresponding ground grid.

[0133] In some embodiments, when the beam pointing of the target satellite within any ground grid is in a pointable state, the element value of the ground grid in the beam matrix is ​​determined to be a first preset value, wherein the first preset value is used to indicate that the beam pointing of the target satellite within the ground grid is in a pointable state; or, when the beam pointing of the target satellite within any ground grid is in a non-pointable state, the element value of the ground grid in the beam matrix is ​​determined to be a second preset value, wherein the second preset value is used to indicate that the beam pointing of the target satellite within the ground grid is in a non-pointable state.

[0134] Step 606: Compress the interference avoidance instructions for the ground grid where the beam directionality is not pointing to obtain the interference avoidance instructions for the target satellite.

[0135] It should be noted that the explanations of steps 601 and 606 can be found in the relevant descriptions in any embodiment of this application, and will not be repeated here.

[0136] In this embodiment, based on the center position of at least one ground grid, a first ground grid with the largest latitude value and a second ground grid with the smallest latitude value are determined from at least one ground grid; a target longitude range is determined based on the first longitude range corresponding to the first ground grid and the second longitude range corresponding to the second ground grid; for any target ground grid, at least one included angle corresponding to the target ground grid is determined based on the position of the target satellite, the center position of the target ground grid, and the target longitude range, wherein at least one included angle is the angle between a first connecting line and at least one second connecting line, the first connecting line is the line connecting the center position of the target ground grid and the position of the target satellite, and at least one second connecting line is the line connecting the center position of the target ground grid and the position of the satellite at at least one candidate longitude, and at least one candidate longitude is determined based on the target longitude range; the beam directivity of the target satellite within the target ground grid is determined based on at least one included angle corresponding to the target ground grid. Therefore, by determining the beam directivity of the target satellite within at least one ground grid covered by the target satellite's communication, based on the center position of the target satellite's communication coverage and the target longitude range, interference can be effectively avoided. In particular, determining the target longitude range based solely on the first longitude range corresponding to the first ground grid with the largest latitude value and the second longitude range corresponding to the second ground grid with the smallest latitude value can significantly reduce the amount of computation and improve execution efficiency.

[0137] Figure 7 This is a flowchart illustrating another method for determining the content of interference avoidance instructions provided in an embodiment of this application.

[0138] In this embodiment of the application, the target longitude range includes a third longitude range corresponding to at least one ground grid. The third longitude range corresponding to at least one ground grid is the farthest GSO longitude range that a third device located at the center of the corresponding ground grid can see at the lowest working elevation angle.

[0139] like Figure 7 As shown, the method for determining the content of the interference avoidance instruction may include the following steps:

[0140] Step 701: Determine multiple ground grids covered by the target satellite's communication based on the target satellite's location.

[0141] Step 702: For any target ground grid, determine at least one included angle corresponding to the target ground grid based on the position of the target satellite, the center position of the target ground grid, and the third longitude range corresponding to the target ground grid.

[0142] Wherein, at least one included angle is the included angle between the first connecting line and at least one second connecting line, the first connecting line is the line connecting the center position of the target ground grid and the position of the target satellite, the at least one second connecting line is the line connecting the center position of the target ground grid and the position of the satellite at at least one candidate longitude, and the at least one candidate longitude is determined based on the third longitude range corresponding to the target ground grid.

[0143] In some embodiments, for any target ground grid, at least one loop can be performed based on the position of the target satellite, the center position of the target ground grid, and the third longitude range corresponding to the target ground grid. In each loop, the included angle of the target ground grid in the current loop is determined based on the position of the target satellite, the center position of the target ground grid, and the candidate longitude of the target ground grid in the current loop. The candidate longitude of the target ground grid in the first loop is the third boundary value of the third longitude range corresponding to the target ground grid, and the included angle of the target ground grid in the current loop is the angle between the first connecting line and the second connecting line of the target ground grid in the current loop. The second connecting line of the target ground grid in the current loop is the line connecting the center position of the target ground grid and the position of the satellite at the candidate longitude of the target ground grid in the current loop. Based on the included angle or the candidate longitude of the target ground grid in the current loop, it is determined whether to stop the loop. If the loop is not stopped, the candidate longitude of the target ground grid in the current loop is updated according to a set step size to obtain the candidate longitude of the target ground grid in the next loop. The included angle of the target ground grid in each loop is determined as at least one included angle corresponding to the target ground grid.

[0144] In some embodiments, the loop may be stopped if the included angle of the target ground grid in the current cycle is less than a set threshold value; or, the loop may be stopped if the candidate longitude of the target ground grid in the current cycle is equal to the fourth boundary value of the third longitude range corresponding to the target ground grid, wherein the fourth boundary value is a boundary value different from the third boundary value.

[0145] The set threshold value can be a preset isolation angle threshold value according to relevant protocols to measure whether the target satellite will affect the GSO satellite. If the included angle of the target ground grid in this cycle is less than the set threshold value, it means that the target satellite is interfering with the communication of the satellite (GSO satellite) at the candidate longitude of the target ground grid in this cycle. At this time, the cycle can be stopped, and it can be determined that the beam pointing of the target satellite in the target ground grid is unpointable.

[0146] The third boundary value can be either the starting or ending boundary value of the third longitude range corresponding to the target ground grid. If the third boundary value is the starting boundary value of the third longitude range corresponding to the target ground grid, then the fourth boundary value is the ending boundary value of the third longitude range corresponding to the target ground grid. In this case, when updating the candidate longitude according to the set step size, the candidate longitude can be gradually increased according to the set step size. If the third boundary value is the ending boundary value of the third longitude range corresponding to the target ground grid, then the fourth boundary value is the starting boundary value of the third longitude range corresponding to the target ground grid. In this case, when updating the candidate longitude according to the set step size, the candidate longitude can be gradually decreased according to the set step size.

[0147] Step 703: Determine the beam directivity of the target satellite within the target ground grid based on at least one included angle corresponding to the target ground grid.

[0148] In some embodiments, if at least one included angle corresponding to the target ground grid is not less than a set threshold value, the beam pointing of the target satellite within the target ground grid is determined to be in a pointable state; or, if at least one included angle corresponding to the target ground grid is less than a set threshold value, the beam pointing of the target satellite within the target ground grid is determined to be in a non-pointable state.

[0149] The explanation of setting the threshold value is given in step 702 and will not be repeated here.

[0150] In some embodiments, a beam matrix can be used to indicate the beam directionality of a target satellite within a corresponding ground grid.

[0151] In some embodiments, when the beam pointing of the target satellite within any ground grid is in a pointable state, the element value of the ground grid in the beam matrix is ​​determined to be a first preset value, wherein the first preset value is used to indicate that the beam pointing of the target satellite within the ground grid is in a pointable state; or, when the beam pointing of the target satellite within any ground grid is in a non-pointable state, the element value of the ground grid in the beam matrix is ​​determined to be a second preset value, wherein the second preset value is used to indicate that the beam pointing of the target satellite within the ground grid is in a non-pointable state.

[0152] Step 704: Compress the interference avoidance instructions for the ground grid where the beam directionality is not pointing to obtain the interference avoidance instructions for the target satellite.

[0153] It should be noted that the explanations of steps 701 and 704 can be found in the relevant descriptions in any embodiment of this application, and will not be repeated here.

[0154] In this embodiment, for any target ground grid, at least one included angle corresponding to the target ground grid is determined based on the position of the target satellite, the center position of the target ground grid, and the third longitude range corresponding to the target ground grid. The at least one included angle is the angle between a first connecting line and at least one second connecting line. The first connecting line is the line connecting the center position of the target ground grid and the position of the target satellite. The at least one second connecting line is the line connecting the center position of the target ground grid and the position of the satellite at at least one candidate longitude. The at least one candidate longitude is determined based on the third longitude range corresponding to the target ground grid. Based on the at least one included angle corresponding to the target ground grid, the beam directivity of the target satellite within the target ground grid is determined. Therefore, by determining the beam directivity of the target satellite within at least one ground grid covered by the target satellite's communication and the target longitude range, interference can be effectively avoided. The target longitude range includes the third longitude range corresponding to at least one ground grid. Determining the included angle based on the third longitude range corresponding to the corresponding ground grid ensures the accuracy of the calculation.

[0155] The following examples illustrate this. Figure 8 This is a flowchart illustrating another method for determining the content of interference avoidance instructions provided in an embodiment of this application.

[0156] like Figure 8 As shown, the method for determining the content of the interference avoidance instruction may include the following steps:

[0157] Step 801, Begin.

[0158] Step 802: Determine the location of the target satellite, set threshold values, and divide the global ground grid.

[0159] In this embodiment, the target satellite can be a medium Earth orbit satellite or a low Earth orbit satellite, and the target satellite can be uniform or non-uniform, with arbitrary inclination angle. The ground grid can be divided according to latitude and longitude, according to geocentric angle, or by uniformly distributed grid points or by partitioning. Once the grid division is completed, it will remain unchanged thereafter.

[0160] In this embodiment of the application, to avoid interference from the target satellite to the GSO satellite, a preset threshold value can be established according to relevant protocols. This preset threshold value is used to measure whether the target satellite will affect the GSO satellite.

[0161] As an example, as shown in Figure 9(a), assuming the target satellite is the NGSO satellite in Figure 9(a), then for a GSO satellite on the GSO arc that co-located with an earth station in a certain region with the target satellite, the angle between the first line (the line connecting the target satellite and the earth station) and the second line (the line connecting the GSO satellite and the earth station) can be calculated. ,like Less than the set threshold value If this occurs, it indicates that the target satellite will interfere with the GSO satellite. In this case, it is necessary to turn off the NGSO satellite's beam pointing towards that area (NGSO satellites use phased array antennas for beamforming to serve multiple terminals) or adjust the beam direction so that the beam is not pointing towards this area. And when... Not less than This indicates that the target satellite will not interfere with the GSO satellite, and normal communication is possible.

[0162] Step 803: Initialize the beam matrix.

[0163] In this embodiment, the beam matrix can be a one-dimensional, two-dimensional, or even higher-dimensional matrix. The beam matrix can be a logical value, a symbol, or a character. For example, True and False, where True indicates pointerable and False indicates non-pointable. Another example is 0 and 1, where 1 indicates pointerable and 0 indicates non-pointable. Yet another example is A and B, where A indicates pointerable and B indicates non-pointable. Still another example is yes and no, where yes indicates pointerable and no indicates non-pointable.

[0164] In this embodiment of the application, the beam matrix ON / OFF[N] can be initialized (assuming that the beam directivity of the target satellite in the corresponding ground grid is initially in a pointable / unpointable state), where N is the total number of ground grids within the beam range of the target satellite.

[0165] Step 804: Determine the position of the target satellite at the current moment, and determine the multiple ground grids covered by the target satellite's communication based on the target satellite's position.

[0166] In this embodiment of the application, the three-dimensional position (Xs, Ys, Zs) of the target satellite at the current moment can be calculated.

[0167] In this embodiment of the application, the ground grid that the target satellite can cover can be determined based on the current position of the target satellite, that is, the ground grid within the beam range of the target satellite.

[0168] Step 805: Record the center position of at least one ground grid covered by the target satellite communication, and determine the longitude range of the target.

[0169] In this embodiment of the application, the center position of at least one ground grid covered by the target satellite communication can be recorded. .in, Indicates the longitude of the center position of ground grid i. This represents the latitude of the center position of ground grid i, where i is the grid number.

[0170] In this embodiment of the application, a first ground grid with the largest latitude value and a second ground grid with the smallest latitude value can be determined based on the center location of at least one ground grid covered by the target satellite communication. Assuming the first ground grid is... The second ground grid is Thus, the farthest GSO longitude range visible to the first device located at the center of the first ground grid at the lowest operating elevation angle can be calculated. ), and the GSO longitude range most visible at the lowest operating elevation angle for the second device located at the center of the second ground grid ( ), and thus from and In the middle, determine the minimum longitude value and maximum longitude value And the longitude range from the minimum longitude value to the maximum longitude value is defined as the target longitude range. ).

[0171] As an example, in the geocentric coordinate system, the range of GSO longitudes at the farthest visible location of a device at the center of the ground grid at the lowest operating elevation angle is shown in Figure 9(b).

[0172] In this embodiment, the target longitude range may include the third longitude range corresponding to at least one ground grid covered by the target satellite communication, thereby allowing the center position of the target satellite communication-covered ground grid to be calculated. The farthest GSO longitude range visible to the target equipment at the lowest operating elevation angle ( (i) refers to the third longitude range corresponding to at least one ground grid covered by the target satellite communication.

[0173] Step 806: Traverse each ground grid i.

[0174] Step 807: Determine the included angle corresponding to ground grid i. .

[0175] In this embodiment of the application, the first connection ( The line connecting (Xs, Ys, Zs) and the second line ( to candidate longitude The angle between the lines connecting the positions of the GSO satellites at that location Among them, candidate longitude It is the first boundary value of the target longitude range ( or ), or the third boundary value of the third longitude range corresponding to ground grid i ( or ).

[0176] Step 808, compare the included angles With set threshold value The size of the longitude is used to determine the candidate longitude. Is it equal to the second boundary value of the target longitude range, or is it equal to the fourth boundary value of the third longitude range corresponding to ground grid i?

[0177] In this embodiment of the application, if Less than If the beam pointing of the target satellite in ground grid i is determined to be in an unpointable state, update the corresponding element value in the beam matrix ON / OFF[N] so that the element value is used to indicate that the beam pointing of the target satellite in ground grid i is in an unpointable state, and return to step 806 to traverse the next ground grid. If all ground grids have been traversed, then execute step 810.

[0178] In this embodiment of the application, if Not less than ,but Equal to the second boundary value of the target longitude range ( or ), or the fourth boundary value of the third longitude range corresponding to ground grid i ( or ), determine that the beam pointing of the target satellite in ground grid i is in a pointable state, update the corresponding element value in the beam matrix ON / OFF[N] so that the element value is used to indicate that the beam pointing of the target satellite in ground grid i is in a pointable state, and return to step 806 to traverse the next ground grid. If all ground grids have been traversed, then execute step 810.

[0179] The second boundary value of the target longitude range is a boundary value that differs from the first boundary value of the target longitude range. For example, if the first boundary value is the starting boundary value of the target longitude range... Then the second boundary value is the termination boundary value of the target longitude range. If the first boundary value is the termination boundary value of the target longitude range. Then the second boundary value is the starting boundary value of the target longitude range. .

[0180] Similarly, the fourth boundary value of the third longitude range corresponding to ground grid i is a boundary value different from the third boundary value of the third longitude range corresponding to ground grid i. For example, if the third boundary value is the starting boundary value of the third longitude range corresponding to the target ground grid. Then the fourth boundary value is the termination boundary value of the third longitude range corresponding to the target ground grid. If the third boundary value is the termination boundary value of the third longitude range corresponding to the target ground grid; Then the fourth boundary value is the starting boundary value of the third longitude range corresponding to the target ground grid. .

[0181] In this embodiment of the application, if Not less than ,and Not equal to the second boundary value of the target longitude range ( or ), or the fourth boundary value of the third longitude range corresponding to ground grid i ( or If the condition is met, then proceed to step 809.

[0182] Step 809, Return to step 807.

[0183] In the embodiments of this application, According to the set step size Gradually select values.

[0184] Among them, if It is the first boundary value of the target longitude range, and the first boundary value is the starting boundary value of the target longitude range. ,or, It is the third boundary value of the third longitude range corresponding to ground grid i, and the third boundary value is the starting boundary value of the target longitude range. Then, according to the set step size, the candidate longitudes are gradually increased;

[0185] like It is the first boundary value of the target longitude range, and the first boundary value is the starting boundary value of the target longitude range. ,or, It is the third boundary value of the third longitude range corresponding to ground grid i, and the third boundary value is the starting boundary value of the target longitude range. Then, the candidate longitudes are gradually reduced according to the set step size.

[0186] Step 810: Compress the interference avoidance instructions for the ground grid in the obtained beam matrix ON / OFF[N] where the beam directionality is in an unpointable state to obtain the interference avoidance instructions for the target satellite.

[0187] In this embodiment, command compression can be performed using a targeted approach. This targeted approach can be command compression based on latitudinal zones, symmetrical latitudinal zones, interference avoidance region envelopes, or symmetrical interference avoidance region envelopes.

[0188] Furthermore, taking instruction compression according to latitude bands as an example, the specific implementation of step 810 is as follows:

[0189] Step 8101: Determine the start time of the interference avoidance instruction content based on different time reference benchmarks, and encode it.

[0190] In this embodiment of the application, the start time of the interference avoidance instruction is the time when the satellite is at its current position.

[0191] Step 8102: Generate the beam pointing image corresponding to the target satellite based on the beam matrix ON / OFF[N].

[0192] Step 8103: Determine the number M of the latitude zones of the target satellite's interference avoidance area based on the beam pointing image.

[0193] Step 8104: Record the latitude zone m of the interference avoidance area and encode it.

[0194] In the embodiments of this application, m∈1, …, M.

[0195] In this embodiment, the latitude zone m of the interference avoidance area corresponding to the longitude interval in the Eastern Hemisphere can be numbered from small to large or from large to small. Correspondingly, the latitude zone m of the interference avoidance area corresponding to the longitude interval in the Western Hemisphere can be numbered from large to small or from small to large. When the longitude interval spans 180° east and west longitude, the number of the corresponding latitude zone m of the interference avoidance area can be from east to west longitude or from west to east longitude. Correspondingly, when the longitude interval spans a meridian, the code of the corresponding latitude zone m of the interference avoidance area can be from west to east longitude or from east to west longitude.

[0196] Step 8105: Determine the latitude identifier of the latitude zone m of the interference avoidance area and encode it.

[0197] In this embodiment of the application, the latitude identifier of the latitude zone m of the interference avoidance area can be recorded by grid number or latitude and longitude coordinates.

[0198] Step 8106: Determine the starting and ending longitude markers of the latitude zone m of the interference avoidance area and encode them.

[0199] In this embodiment of the application, the starting and ending longitudes of the interference avoidance area latitude zone m can be determined by traversing the longitude grid associated with the interference avoidance area latitude zone m and recording its minimum and maximum longitude values.

[0200] Step 8107: Execute m=m+1 and return to step 8104.

[0201] Step 8108: Generate the interference avoidance instruction content for the target satellite based on the start time of the interference avoidance instruction content, the number M of the interference avoidance area latitude bands, and the encoding data of each interference avoidance area latitude band.

[0202] As an example, the interference avoidance instructions for the target satellite are shown in the table below:

[0203] Table 2 Example 2 of Interference Avoidance Instructions for Target Satellites

[0204]

[0205] Taking the target satellite as an NGSO satellite with an altitude of 1200 km as an example, assume that the latitude and longitude identifier codes each occupy 16 bits.

[0206] Figure 4 A schematic diagram of the latitudinal band of the interference avoidance region in the beam pointing image is shown. Figures 5(a)-5(d) Figure 5(a) shows a schematic diagram of the latitude band of the interference avoidance region when using different target methods for command compression. Figure 5(b) shows a schematic diagram of the latitude band of the interference avoidance region when using the latitude band method for command compression. Figure 5(c) shows a schematic diagram of the latitude band of the interference avoidance region when using the interference avoidance region envelope method for command compression. Figure 5(d) shows a schematic diagram of the latitude band of the interference avoidance region when using the symmetrical interference avoidance region envelope method for command compression.

[0207] As shown in Figure 5(a), if command compression is performed using latitude bands, the compression is based on the start and end longitudes of the interference avoidance area latitude band. Each interference avoidance area latitude band occupies 48 bits of space, and each group of beam interference avoidance commands contains a maximum of approximately 35 interference avoidance area latitude bands; therefore, the maximum command storage size does not exceed 210 bytes. If stored in the form of ground latitude and longitude grid blocks, the required storage space is approximately 15,000 bytes, saving approximately 98.6% of the storage space.

[0208] As shown in Figure 5(b), if command compression is performed using a symmetrical latitudinal band method, then due to Figure 4 The interference avoidance zone latitude band shown is symmetrical about the target satellite's nadir point. Therefore, only the symmetrical half of the interference avoidance zone latitude band is compressed according to its starting and ending longitudes. Using this method, the maximum instruction storage size does not exceed 170 bytes, saving approximately 98.87% of storage space.

[0209] As shown in Figure 5(c), if instruction compression is performed using the interference avoidance region envelope method, then the instruction compression is performed according to the envelope of the latitudinal band of the interference avoidance region. Using this method, the maximum instruction storage size does not exceed 840 bytes, saving approximately 94.4% of storage space.

[0210] As shown in Figure 5(d), if command compression is performed using a symmetrical interference avoidance region envelope method, then due to Figure 4 The interference avoidance area latitude band shown is symmetrical about the target satellite's nadir point. Therefore, only the symmetrical half of the interference avoidance area latitude band is compressed according to the envelope of the interference avoidance area latitude band. Using this method, the maximum instruction storage size does not exceed 500 bytes, saving approximately 96.67% of storage space.

[0211] This application provides four flexible and efficient compression methods for GSO system interference avoidance command packets, which can compress interference avoidance command packets, reduce storage space requirements, and improve command cache efficiency.

[0212] Step 811, End.

[0213] In summary, this application takes the interference avoidance of GSO satellites by low-Earth orbit / medium-Earth orbit communication satellites as its starting point. It not only refines the generation of interference avoidance instructions, but also compresses the interference avoidance instructions according to the latitude zones divided by the interference avoidance area, thereby reducing the amount of stored data.

[0214] To implement the above embodiments, this application also proposes an interference avoidance instruction content determination device.

[0215] Figure 10 This is a schematic diagram of the structure of an interference avoidance instruction content determination device provided in an embodiment of this application.

[0216] like Figure 10 As shown, the interference avoidance instruction content determination device includes: a first determination module 901, a second determination module 902, and a processing module 903.

[0217] The first determining module 901 is used to determine multiple ground grids covered by the target satellite's communication based on the target satellite's location;

[0218] The second determining module 902 is used to determine the beam directivity of the target satellite in the corresponding ground grid based on the position of the target satellite, the center position of at least one of the ground grids and the target longitude range, wherein the target longitude range is the geostationary satellite orbit (GSO) longitude range of at least one of the ground grids to be avoided.

[0219] The processing module 903 is used to compress the interference avoidance instructions of the ground grid whose beam directionality is not pointing to obtain the interference avoidance instruction content of the target satellite.

[0220] Furthermore, in one possible implementation of the embodiments of this application, the above-mentioned apparatus further includes:

[0221] The generation module is used to generate a beam pointing image corresponding to the target satellite based on the beam pointing of the target satellite in the corresponding ground grid, wherein the beam pointing image uses pixels to indicate the beam pointing of the target satellite in the corresponding ground grid.

[0222] Furthermore, in one possible implementation of this application embodiment, the processing module 903 includes:

[0223] The first determining unit is used to determine the latitude zone of the interference avoidance area of ​​the target satellite based on the pixels in the beam pointing image where the beam pointing is in an unpointable state, wherein the latitude value of any of the interference avoidance area latitude zones is the same.
