Abstract
Description
Technical Field
[0001] The present invention relates to the field of aviation technology, and in particular to a method and device for determining functional partition parameters of a measurement and control arc segment. Background Art
[0002] During the task planning process of measurement and control activities, the implementation of each task needs to meet certain specific conditions. For example, the antenna elevation angle of the measurement and control equipment must be higher than a certain angle, and there must be no obstructions between the measurement and control antenna and the tracking target, etc. Therefore, it is always necessary to calculate the time when these specific conditions are met to provide a reference time for the design and arrangement of related instructions and events.
[0003] Existing technologies differentiate their designs for different types of spacecraft and different types of measurement and control equipment, making special designs for various special situations, and even making special designs for each spacecraft. For example, the definition and calculation method of the reference time of "data reception start" is adopted in the existing technical solutions as follows:
[0004] For land-based fixed tracking and control stations: take the maximum of the two moments when the elevation angle is x degrees and when the station is visible without obstruction.
[0005] For mobile survey vessels at sea: take the elevation angle x degrees at the moment + ΔT.
[0006] Spacecraft A, Spacecraft B: ΔT = 0s.
[0007] Spacecraft C, spacecraft D and spacecraft E: ΔT = 180s.
[0008] The existing technology calculates the reference time separately for specific situations, which increases the complexity of project implementation and the difficulty of system use and maintenance. It lacks continuity, consistency and inheritance, and is not convenient for project implementation. Summary of the Invention

[0048] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention. It should be noted that, unless there is a conflict, the embodiments and features in the embodiments of this application can be combined with each other in any manner.
[0049] Definitions of Abbreviations and Key Terms:
[0050] The TT&C arc, abbreviated as the arc, refers to the time range during which ground-based TT&C equipment can observe a spacecraft while it's in orbit. Within this arc, the spacecraft's antenna terminals point toward the ground-based TT&C equipment, allowing the ground to receive downlink data from the spacecraft. Once dual-capture is complete, the ground can send remote control commands and upload flight parameters to the spacecraft, enabling TT&C.
[0051] Uplink carrier: The signal carrier that is amplified and frequency modulated by the uplink transmitting equipment and transmitted to the spacecraft receiver. It is the basis for spacecraft uplink control.
[0052] Dual capture: Bidirectional capture, also known as bidirectional carrier capture, is an important part of the target capture process under the coherent forwarding tracking and control system. The spacecraft carries a phase-locked transponder. When it does not receive the carrier transmitted by the ground equipment, it sends a beacon signal with a modulated downlink data receiving subcarrier. Once the ground equipment is aligned with the target (the target falls within the main antenna beam), the ground receiver quickly captures the transponder beacon signal and sends a carrier lock indication. The ground equipment then transmits an uplink unmodulated carrier signal and starts scanning the uplink carrier frequency after a certain delay. After the transponder locks the uplink scanning carrier signal, it performs coherent forwarding, and the ground receiver scans along. At the same time, it controls the transmitter to stop scanning the uplink carrier frequency and return to the carrier center frequency according to a certain pattern, achieving the so-called "return to zero". At this point, dual capture is completed.
[0053] Occlusion: During space tracking and control activities, the inability of ground-based tracking and control equipment to observe the spacecraft's antenna terminals is called an occlusion. Any object that causes an obstruction is considered an occlusion, such as mountains, trees, buildings, the spacecraft itself, and even the Earth.
[0054] Stable tracking: On the premise that dual capture is completed, if the measurement and control system determines that the uplink and downlink data transmission are stable, it is considered that stable tracking of the spacecraft has been achieved.
[0055] Elevation angle: The angle between the antenna of the measurement and control equipment and the horizontal plane.
[0056] Elevation rise phase: The phase in which the device antenna gradually rises from the horizon with the spacecraft until the elevation angle reaches the highest position.
[0057] Elevation descent phase: The phase in which the device antenna gradually descends from the highest elevation position to below the horizon along with the spacecraft.
[0058] Figure 1 FIG. 1 is a flow chart of a method for determining functional partition parameters of a measurement and control arc segment provided by an embodiment of the present invention. Figure 1 As shown, the method for determining the functional partition parameters of the measurement and control arc provided by the embodiment of the present invention includes:
[0059] Step S1: Obtain the visibility parameters of the measurement and control arc segment.
[0060] Step S2: determining the downlink data receiving area parameters according to the line-of-sight area parameters and the time corresponding to when the device antenna elevation angle is a first preset angle; the time corresponding to the first preset angle corresponds to the elevation angle rising stage and the elevation angle falling stage respectively.
[0061] Step S3: traverse all measurement and control arcs to determine the functional partition parameters corresponding to each measurement and control arc; the functional partition parameters at least include the line-of-sight area parameters and the downlink data receiving area parameters.
[0062] In the above step S1, the device obtains the parameters of the visual area of the measurement and control arc segment. The device can be a computer device that executes the method. The visual area, such as Figure 2 The area shown in the figure refers to the unobstructed part of the measurement and control arc. Measurement and control activities should be carried out within the line of sight area. Usually, the line of sight area is separate and continuous.
[0063] The visibility area parameters, that is, the time range of the visibility area can be directly obtained from the measurement and control forecast data file without the need for recalculation.
[0064] Let V represent the visibility parameter of the measurement and control arc segment, and
[0065] V=[V s ,V e ],
[0066] Among them, [V s ,V e ] is a closed interval, V s 、V e They respectively indicate the start and end time of the viewing area.
[0067] In step S2, the device determines the downlink data receiving zone parameters based on the visual range parameters and the time corresponding to when the device antenna elevation angle is at a first preset angle; the time corresponding to the first preset angle corresponds to the elevation angle rising phase and the elevation angle falling phase, respectively. The downlink data receiving zone refers to the period of time within the tracking and control arc during which data transmitted by the spacecraft can be received.
[0068] Under the current measurement and control system, the setting of the downlink data receiving area generally has an elevation angle requirement, requiring the elevation angle of the device antenna to reach a certain value before the downlink data can be received.
[0069] Let U x Indicates the moment when the elevation angle of the device antenna is x degrees during the elevation rising phase (Up), corresponding to the first preset angle corresponding to the moment in the elevation rising phase;
[0070] Let D xIndicates the moment when the elevation angle of the device antenna is x degrees during the elevation angle decrease (Down) phase; corresponds to the first preset angle in the elevation angle decrease phase;
[0071] Remember the closed interval [U x ,D x ] is the time range in which the elevation angle meets the downlink data reception requirements.
[0072] Let Y represent the downlink data receiving area parameter of the measurement and control arc segment, and record
[0073] Y=[Y s ,Y e ],
[0074] Since all measurement and control activities are carried out within the line of sight, there are
[0075] Y=[Y s ,Y e ]
[0076] =[V s ,V e ]∩[U x ,D x ]
[0077] Among them, Y s 、Y e Respectively represent the start and end time of the downlink data receiving area, symbol V s 、V e 、U x 、D x The meaning of is as described above.
[0078] In step S3, the device traverses all measurement and control arcs and determines the functional partition parameters corresponding to each measurement and control arc; the functional partition parameters include at least the line-of-sight area parameters and the downlink data receiving area parameters. The functional partition parameters may include line-of-sight area parameters, downlink data receiving area parameters, carrier adjustable area parameters, initial carrier holding area parameters, stable tracking area parameters, preparatory remote control area parameters, final carrier holding area parameters, and uplink command area parameters.
[0079] The method for determining the functional zoning parameters of a measurement and control arc segment provided by an embodiment of the present invention obtains the line-of-sight area parameters of the measurement and control arc segment; determines the downlink data receiving area parameters according to the line-of-sight area parameters and the moment corresponding to the elevation angle of the device antenna being a first preset angle; the moment corresponding to the first preset angle corresponds to the elevation angle rising stage and the elevation angle falling stage, respectively; traverses all measurement and control arc segments to determine the functional zoning parameters corresponding to each measurement and control arc segment; the functional zoning parameters include at least the line-of-sight area parameters and the downlink data receiving area parameters, which can improve the versatility and adaptability of the functional zoning parameter determination method and facilitate engineering implementation.
[0080] Furthermore, the functional partition parameters also include carrier adjustable region parameters; accordingly, the method for determining the functional partition parameters of the measurement and control arc segment also includes:
[0081] The carrier adjustable range parameters are determined based on the visibility parameters, a first preset time duration for delay protection, and the time corresponding to when the device antenna elevation angle reaches a second preset angle; the time corresponding to the second preset angle corresponds to the elevation angle rising phase and the elevation angle falling phase, respectively. The carrier adjustable range refers to the period in the tracking and control arc during which the tracking and control equipment can adjust the spacecraft's uplink carrier.
[0082] The carrier's adjustable area must be within the line of sight, and elevation angle requirements are typically specified. The calculation method and parameter settings are determined based on factors such as the measurement and control system and equipment specifications. Adjusting the uplink carrier requires coordinated judgment from both the uplink and downlink (see the "dual capture" concept).
[0083] The measurement and control equipment can adjust or de-adjust the uplink carrier of the spacecraft at any time within the carrier adjustable range.
[0084] Under the current measurement and control system, the setting of the carrier adjustable zone also has elevation angle requirements, requiring the elevation angle of the equipment antenna to reach a certain value before the uplink carrier can be adjusted.
[0085] Let U y Indicates the moment when the device antenna elevation angle is y degrees during the elevation rising phase (Up); corresponds to the second preset angle corresponding to the moment during the elevation rising phase;
[0086] Let D y Indicates the moment when the elevation angle of the device antenna is y degrees during the elevation angle decrease (Down) phase; corresponds to the second preset angle corresponding to the moment during the elevation angle decrease phase;
[0087] Remember the closed interval [U y ,D y ] is the time range in which the elevation angle meets the requirements for modulating the uplink carrier.
[0088] In addition, since the device generates radiation when modulating the uplink carrier, in order to minimize adverse effects on the surrounding environment, not only is the elevation angle of the device antenna required to reach a certain value, but in some areas, there is also delay protection, requiring a period of time before the uplink carrier modulation operation can be performed to protect personnel and the environment. protect is the length of time for delayed protection, and the closed interval [U y +Δ protect ,D y -Δ protect ] is the time range within which the elevation angle meets the requirements of the uplink carrier modulation and takes into account the delay protection factor. protect Corresponding to the first preset time length.
[0089] Let W represent the carrier adjustable area parameter of the tracking arc segment, and
[0090] W=[W s ,W e ],
[0091] Similarly, since all measurement and control activities must be carried out within the line of sight, there are
[0092] W=[W s ,W e ]
[0093] =[V s ,V e ]∩[U y +Δ protect ,D y -Δ protect ]
[0094] Among them, W s 、W e Respectively represent the start and end time of the carrier adjustable area, symbol V s 、V e 、U y 、D y , Δ protect The meaning of is as described above.
[0095] Furthermore, the functional partition parameters also include initial carrier holding zone parameters; accordingly, the method for determining the functional partition parameters of the measurement and control arc segment also includes:
[0096] The initial carrier holding zone parameters are determined based on the carrier adjustable range parameters and a second preset time length required for the device to complete dual acquisition. The initial carrier holding zone refers to the period within the carrier adjustable range during which the carrier remains in a modulated state. This period lasts from the completion of dual acquisition (the time required for dual acquisition varies depending on the type of measurement and control equipment) until the end of the carrier adjustable range.
[0097] The initial carrier holding area of a measurement and control arc is a fixed value.
[0098] Let H represent the initial carrier holding area parameter of the tracking arc segment, and record
[0099] H=[H s ,H e ],
[0100] According to the definition of the initial carrier holding area, there is
[0101] H=[H s ,H e ]
[0102] =[W s+Δ capture ,W e ]
[0103] Among them, H s 、H e Respectively represent the start and end time of the initial carrier holding area, Δ capture It is the time required for the device to complete dual capture, symbol W s 、W e The meaning of is as described above. capture Corresponding to the second preset time length.
[0104] Furthermore, the functional partition parameters also include stable tracking area parameters; accordingly, the method for determining the functional partition parameters of the measurement and control arc segment also includes:
[0105] The stable tracking area parameters are determined based on the initial carrier holding area parameters, the line of sight area parameters and a third preset time length for downlink data transmission of the device. The stable tracking area refers to a period in the tracking and control arc segment where both uplink and downlink data transmission are stable.
[0106] During the period of stable uplink data transmission, the initial carrier holding area is taken as its theoretical value.
[0107] During periods of stable downlink data transmission, a time period is deducted from each end of the downlink data receiving area, and the remaining period is used as the theoretical value. Based on historical experience and practical verification, unstable data transmission and data loss can occur at the beginning and end of the downlink data receiving area. To ensure data quality, a time period is deducted from each end of the downlink data receiving area, and the remaining period is considered stable. This deducted time is called the impact margin and is set based on empirical values.
[0108] Let K represent the stable tracking area parameter of the measurement and control arc segment, and record
[0109] K=[K s ,K e ],
[0110] According to the definition of stable tracking area, there are
[0111] K=[K s ,K e ]
[0112] =[H s ,H e ]∩[Y s +Δ stable ,Y e -Δ stable ]
[0113] Among them, K s , Ke Respectively represent the start and end time of the stable tracking area, Δ stable The length of time that affects the margin set to stabilize the downlink data transmission of the device, symbol H s 、H e 、Y s 、Y e The meaning of is as described above. stable Corresponding to the third preset time length.
[0114] Furthermore, the functional zoning parameters also include parameters of a preliminary remote control area; accordingly, the method for determining the functional zoning parameters of the measurement and control arc segment also includes:
[0115] The parameters of the preliminary remote control zone are determined based on the parameters of the initial carrier holding zone, the parameters of the line-of-sight zone, and the time corresponding to when the device antenna elevation angle reaches a third preset angle; the time corresponding to the third preset angle corresponds to the elevation angle rising phase and the elevation angle falling phase, respectively. During measurement and control activities, due to various reasons, not every arc segment will actually adjust the uplink carrier; however, every arc segment that meets the conditions must be prepared to issue uplink commands.
[0116] The so-called preparatory remote control area is a period of time calculated and determined according to a set method, assuming that the arc segment adds uplink carrier, completes dual capture, and forms stable tracking.
[0117] In actual applications, when the arc segment does not add an uplink carrier, the preparatory remote control area of the arc segment can still be calculated, but the uplink command cannot be implemented and it is only in the "preparatory remote control" state.
[0118] The preliminary remote control area is determined based on the stable tracking area and the elevation angle requirements. The calculation method and parameter settings are determined based on factors such as equipment specifications.
[0119] Under the current measurement and control system, the setting of the preparatory remote control area also has elevation angle requirements, which requires that the elevation angle of the equipment antenna reach a certain value before remote control preparation can be carried out.
[0120] Let U z Indicates the moment when the device antenna elevation angle is z degrees during the elevation rising (Up) phase; corresponds to the moment when the third preset angle in the elevation rising phase is reached;
[0121] Let D z Indicates the moment when the elevation angle of the device antenna is z degrees during the elevation angle decrease (Down) phase; corresponds to the moment when the third preset angle in the elevation angle decrease phase is reached;
[0122] Remember the closed interval [U z ,D z ] is the time range within which the elevation angle meets the preparatory remote control requirements.
[0123] Let T represent the parameters of the preparatory remote control area of the measurement and control arc segment, and
[0124] T=[T s ,T e ],
[0125] According to the definition of the preparatory remote control area, there are
[0126] T=[T s ,T e ]
[0127] =[U z ,D z ]∩[K s ,K e ]
[0128] =[U z ,D z ]∩[H s ,H e ]∩[Y s +Δ stable ,Y e -Δ stable ]
[0129] Among them, T s 、T e Respectively represent the start and end time of the preparatory remote control area, symbol U z 、D z , K s , K e 、H s 、H e 、Y s 、Y e , Δ stable The meaning of is as described above.
[0130] Furthermore, the functional partition parameters also include final-state carrier holding area parameters; accordingly, the method for determining the functional partition parameters of the measurement and control arc segment also includes:
[0131] The preset carrier switching algorithm is called to determine the parameters of the final carrier holding zone corresponding to each measurement and control arc segment. In actual measurement and control activities, multiple measurement and control arc segments are usually called to participate in measurement and control. In the overlapping part, only one arc segment is allowed to maintain the carrier modulation state. Therefore, carrier switching will be performed between arc segments, and there must be an arc segment that cannot maintain the carrier modulation state throughout the entire process. Using different carrier switching algorithms will produce different carrier switching results, and the range of the arc segment's carrier holding zone will also be different. The final state of the arc segment's carrier holding zone is called the final carrier holding zone.
[0132] The final carrier holding area needs to call the relevant algorithm of carrier switching, take the initial carrier holding area as input, and calculate the final carrier holding area. The relevant algorithm of carrier switching can adopt the mature algorithm in this field. Calling the relevant algorithm of carrier switching to determine the parameters of the final carrier holding area is also an existing method in this field, and the embodiments of the present invention will not be repeated here.
[0133] In the case of only one arc segment, the final carrier holding area of the arc segment is completely consistent with the initial carrier holding area.
[0134] In the case where multiple arc segments are overlapped, there is at least one arc segment whose final carrier holding area is inconsistent with the initial carrier holding area.
[0135] make Indicates the final carrier holding area parameter of the measurement and control arc segment,
[0136]
[0137] Furthermore, the functional zoning parameters also include uplink command zone parameters; accordingly, the method for determining the functional zoning parameters of the measurement and control arc segment also includes:
[0138] Traverse all measurement and control arcs and determine the uplink command zone parameters based on the final carrier holding zone parameters and the preparatory remote control zone parameters. As mentioned in the introduction to the preparatory remote control zone concept, the calculation and determination of the preparatory remote control zone assumes that the arc has added uplink carrier modulation, achieved dual acquisition, and established stable tracking. This is simply the "preparatory remote control" state. For uplink commanding, the arc must actually add uplink carrier modulation and achieve dual acquisition.
[0139] Therefore, the so-called uplink command area is the intersection of the final state carrier holding area and the preparatory remote control area. It is the period in the measurement and control arc during which uplink commands can be issued to the spacecraft.
[0140] Let C represent the parameters of the uplink command area of the measurement and control arc segment, and
[0141] C=[C s ,C e ],
[0142] According to the definition of the upward command area, there are
[0143]
[0144] Among them, C s 、C e Respectively represent the start and end time of the upward command zone, symbol T s 、T e 、 The meaning of is as described above.
[0145] Functional zoning parameter configuration method for measurement and control arc
[0146] To facilitate software development and engineering implementation, the unified parameter configuration method is shown in Table 1 below:
[0147] Table 1
[0148]
[0149] like Figure 3 As shown in the figure, the method for determining the functional partition parameters of the measurement and control arc is described as follows:
[0150] Step 1: Figure 3 As shown in the figure 1, the visibility area is directly obtained from the TT&C forecast data file. The visibility area parameters of the TT&C arc are obtained.
[0151] Step 2: Figure 3 As shown in the figure 2, the downlink data receiving area of the arc segment is calculated. The downlink data receiving area parameter is determined based on the line-of-sight area parameter and the time corresponding to the first preset angle when the device antenna elevation angle is corresponding to the elevation angle rising stage and the elevation angle falling stage respectively.
[0152] Step 3: Figure 3 As shown in the figure 3, the carrier adjustable range of the arc segment is calculated. The carrier adjustable range parameter is determined based on the visibility zone parameter, the first preset time length for delay protection, and the time corresponding to the device antenna elevation angle being a second preset angle; the time corresponding to the second preset angle corresponds to the elevation angle rising phase and the elevation angle falling phase, respectively.
[0153] Step 4: Figure 3 As shown in the mark 4, the initial carrier holding area of the arc segment is calculated and the initial carrier holding area parameters are determined according to the carrier adjustable area parameters and the second preset time length required for the device to complete dual capture.
[0154] Step 5: Figure 3 As shown in the mark 5, the stable tracking area of the arc segment is calculated. The stable tracking area parameters are determined according to the initial carrier holding area parameters, the line of sight area parameters and the third preset time length for downlink data transmission of the device.
