Technical Field

[0001] This disclosure relates to the field of satellite communication technology, specifically to a method, apparatus, and equipment for planning the power supply link of a target constellation system. Background Technology

[0002] Currently, satellite constellation systems are developing rapidly, providing high-speed internet access globally. However, the deployment of large-scale constellation systems also brings a series of technical challenges, especially interference between constellation systems, such as interference between low-Earth orbit (LEO) and high-Earth orbit (HEO) constellations, interference between medium-Earth orbit (MEO) and high-Earth orbit (HEO) constellations, and interference between LEO and MEO constellations.

[0003] Interference may occur in the communication feeder links of different constellation systems within a certain area, which may affect the communication quality and signal stability of satellite communication, and may even lead to communication interruption.

[0004] Therefore, a constellation system usually needs to take certain interference avoidance measures to protect other satellite systems. Summary of the Invention

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0021] Please see Figure 1 The present disclosure provides a method for planning the power supply links of a target constellation system, which may include the following steps.

[0022] S1: Obtain the link parameters of multiple power supply links of the target constellation system, including resource allocation parameters, link establishment time parameters, and communication quality parameters.

[0023] In this embodiment, each feeder link can characterize a communication link between a satellite and a satellite feeder station. After a feeder link is formed, its attribute information can be measured and obtained, such as the communication resources allocated to the feeder link, the link establishment time, and the communication quality information.

[0024] In some implementations, the target constellation system can be a low-Earth orbit (LEO) constellation system, which can resolve the interference problem between LEO and high-Earth orbit (HEO) constellation systems, as well as the interference problem between LEO and mid-Earth orbit (MEO) constellation systems.

[0025] In some implementations, the target constellation system can be a mid-orbit constellation system, which can resolve interference between mid-orbit and high-orbit constellation systems.

[0026] It should be noted that low-Earth orbit (LEO), medium-Earth orbit (MEO), and high-Earth orbit (HEO) constellations are typically distinguished by the altitude of their satellite orbits above the Earth's surface. For example, LEO constellations generally operate at altitudes between 500 and 2000 kilometers; MEO constellations typically operate at altitudes between 2000 and 36000 kilometers; and HEO constellations typically operate at altitudes around 36000 kilometers. When interference occurs between constellation systems, the lower-Earth orbit system handles link avoidance, requiring adjustments to fewer parameters and within a smaller scope. This reduces the complexity of coordination between constellation systems and also saves on coordination costs.

[0027] S2: Determine the link score of the power supply link based on the link parameters.

[0028] In this embodiment, based on the link parameters, various attribute information of the power supply link can be obtained, thereby enabling the use of standardized methods to scientifically evaluate the current state of each power supply link and determine the adjustment requirements for each power supply link.

[0029] In some implementations, determining the link score of the power supply link based on the link parameters includes: determining a first score based on the resource allocation parameters; determining a second score based on the link establishment time parameters; determining a third score based on the communication quality parameters; and performing a weighted statistical analysis on the first score, the second score, and the third score to determine the link score.

[0030] Specifically, determining the link score of a power supply link can comprehensively consider multiple scoring dimensions (resource allocation, time retention, and communication quality) to accurately reflect whether the link needs adjustment and the extent of such adjustment. The calculation results for each scoring dimension can be weighted to highlight or weaken the reference value of certain dimensions. Depending on the actual application scenario, the weight of each scoring dimension can be subjectively assigned (e.g., user-controlled input) or objectively assigned (e.g., pre-agreed upon according to industry standards).

[0031] In a practical application example, the link score of the feeder link can be calculated using the following formula.

[0032]

[0033] Where S is the link score. , , They are respectively the first rating, the second rating, and the third rating. , , These are the corresponding weights. Each weight can be determined by both subjective and objective weighting.

[0034] In some implementations, determining the first score based on the resource allocation parameters includes: determining the current resource allocation amount, the lower limit of link establishment resources, and the upper limit of link establishment resources for the power supply link based on the resource allocation parameters; determining the difference between the current resource allocation amount and the lower limit of link establishment resources as a first factor; determining the difference between the upper limit of link establishment resources and the lower limit of link establishment resources as a second factor; and determining the ratio of the first factor to the second factor as the first score.

[0035] In a practical application example, the link establishment resources used by all feeder links (L1, L2, ..., Ln) on all feeder stations of the target satellite system should be optimized. That is, the resource usage of the n feeder links should be in an average state to ensure a balanced allocation of overall system resources and to ensure that communication resources are evenly distributed to each feeder station. On the one hand, it is necessary to avoid a feeder link being in a state of resource saturation for a long time; on the other hand, it is also necessary to avoid a feeder link being in a state of resource idleness for a long time.

[0036] At a given time, assuming the current resource allocation for each feeder link is... The current resource allocation can be converted into a normalized index using the following conversion formula. .

[0037]

[0038] in, This represents the minimum communication resources required to establish a power supply link (lower limit of link establishment resources). This represents the maximum communication resources that can be allocated to establish a power supply link (link establishment resource limit). Normalized index. This can be designated as the first score. Using the first score can accurately reflect the resource allocation status of a certain feedback loop.

[0039] In some implementations, determining the second score based on the link establishment duration parameter includes: determining the current link establishment duration, the lower limit of the link establishment duration, and the upper limit of the link establishment duration for the power supply link based on the link establishment duration parameter; determining the difference between the current link establishment duration and the lower limit of the link establishment duration as a third factor; determining the difference between the upper limit of the link establishment duration and the lower limit of the link establishment duration as a fourth factor; and determining the ratio of the third factor to the fourth factor as the second score.

[0040] In a practical application example, the connection establishment time of all feeder links (L1, L2, ..., Ln) on all feeder stations of the target satellite system should maintain a certain connection establishment time to ensure optimal communication duration of the satellite system's feeder links. On the one hand, it is necessary to avoid a link being in a continuous connection establishment state; on the other hand, it is also necessary to avoid a link being in a continuous non-connection establishment state.

[0041] At a given time, assuming the current resource allocation for each feeder link is... The current resource allocation can be converted into a normalized index using the following conversion formula. .

[0042]

[0043] in, This indicates the minimum duration that the power supply link needs to be maintained after it is established (lower limit of link establishment time). This indicates the maximum duration that the power supply link can be maintained after it is established (upper limit of link establishment time). Normalized index. This can be designated as the second score. Using the second score can accurately reflect the duration of a feedback link's hold-up status.

[0044] In some implementations, determining the third score based on the communication quality parameters includes: determining the current signal-to-noise ratio (SNR), lower SNR limit, and upper SNR limit of the power supply link based on the link establishment time parameter; determining the difference between the current SNR and the lower SNR limit as a fifth factor; determining the difference between the upper SNR and the lower SNR limit as a sixth factor; and determining the ratio of the fifth factor to the sixth factor as the third score.

[0045] In a practical application example, all feed links (L1, L2, ..., Ln) on all feed stations of the target satellite system should maintain a certain communication quality to ensure that the feed link establishment quality of the satellite system is optimal and that the signal-to-noise ratio of each link is not too low.

[0046] At a given time, assuming the current signal-to-noise ratio of each feeder link is... The current resource allocation can be converted into a normalized index using the following conversion formula. .

[0047]

[0048] in, This represents the minimum signal-to-noise ratio (SNR) that needs to be maintained after the power supply link is established (lower SNR limit). This represents the maximum achievable signal-to-noise ratio (SNR) after the power supply link is established (SNR upper limit). Normalized index This can be designated as the third rating. Using the third rating can accurately reflect the communication quality status of a feedback link.

[0049] S3: Based on the link score, formulate an interference avoidance strategy for the power supply link. The interference avoidance strategy includes at least one of adjusting the satellite transmission power, shutting down the power supply link, and switching the power supply link.

[0050] In this embodiment, the necessity of adjusting each feeder link can be determined based on the link score. For example, only links that meet preset scoring criteria require adjustment. Based on the link score, each feeder link can also be prioritized, allowing for the determination of which feeder links require priority in interference avoidance strategies.

[0051] In this embodiment, the interference avoidance strategy can be formulated using a pre-trained machine learning model. This allows for the selection of the most suitable adjustment scheme for each feedback link from among options such as adjusting satellite transmit power, shutting down the feed link, and switching the feed link, while ensuring the overall communication performance of the target satellite system. This effectively improves the overall resource utilization efficiency of the target satellite system.

[0052] In some implementations, formulating the interference avoidance strategy for the feed link includes determining the interference avoidance angle of the target feed station, the interference avoidance angle being determined based on at least one of the following parameters: the negotiated interference-to-noise ratio threshold between the affected satellite system and the target constellation system; the satellite transmit power of the target constellation system; the satellite transmit antenna gain of the target constellation system; the angle between a first connection and a second connection, the first connection being the connection from the satellite of the affected satellite system to the feed station of the affected satellite system, and the second connection being the connection from the satellite of the affected satellite system to the feed station of the target constellation system; the maximum receive gain of the feed station antenna of the affected satellite system; the equivalent noise temperature of the receiver of the feed station of the affected satellite system; the communication bandwidth of the affected satellite system; the Boltzmann constant; and the transmission loss of the feed link.

[0053] Specifically, the target constellation system implementing this method can be viewed as the interfering satellite system, which can proactively take certain interference avoidance measures to protect other satellite systems (the interfered satellite system). The negotiated interference-to-noise ratio threshold value can represent a noise ratio threshold parameter that is acceptable to both the target constellation system and the interfered constellation system.

[0054] It should be noted that the noise ratio threshold, satellite transmit power, satellite transmit antenna gain, satellite coordinates, feed station coordinates, and feed link transmission loss of the target constellation system are all known information of the target constellation system. The noise ratio threshold, satellite coordinates, feed station coordinates, maximum receive gain of the feed station antenna, equivalent noise temperature of the feed station receiver, and communication bandwidth of the interfered satellite system need to be pre-transmitted by each interfered satellite system to the target constellation system so that the target constellation system can formulate appropriate interference avoidance strategies. This approach protects the communication quality of the interfered satellite system while also maximizing the communication quality of the target constellation system itself.

[0055] Please see Figure 2 In a practical application scenario of target satellite system interference avoidance, the affected constellation (satellite) system is A, consisting of satellite A and feed station A. The interfering constellation (satellite) system is B, consisting of satellite B and feed station B. During the operation of the two constellation systems, their uplink and downlink links may cross and cause interference. For example, when satellite A, satellite B, and feed station A are collinear, satellite B needs to perform angular isolation to avoid interfering with satellite A. In this case, if satellite B is taken as the starting point, the interference avoidance angle of satellite B is the angle between feed station A, satellite B, and feed station B, i.e., φmin; if feed station B is taken as the starting point, the interference avoidance angle of feed station B is the angle between satellite B, feed station B, and satellite A, i.e., θmin. Using the interference-to-noise ratio (I / N) as an indicator for interference assessment, the value of the interference avoidance angle of satellite B or feed station B can be derived from the I / N threshold value acceptable to both the affected and interfering systems (e.g., -12.2dB). For example, the interference avoidance angle of feed station B can be expressed as:

[0056]

[0057] In the formula, ( I / N ) th This is the I / N threshold value acceptable to both the disturbed constellation system and the interfering constellation system, which is also the negotiated interference-to-noise ratio threshold value, and the data unit is dB; p B The data represents the satellite transmit power of the interfering constellation system B, in dBW. G B-tx The satellite transmitting antenna gain of the interfering constellation system B is expressed in dBi. G is the angle between the line connecting satellite A to feeder station A (first line) of the disturbed constellation system A and the line connecting satellite A to feeder station B (second line) of the disturbed constellation system A; re-max The maximum receiving gain of antenna A, the feed station of constellation system A, is expressed in dBi. T The equivalent noise temperature of the receiver at the feeder station of the disturbed system A is given in Kelvin. W The communication bandwidth of the disturbed system A is given in Hz. k B Here is the Boltzmann constant, with a value of 1.38 × 10⁻⁶. −23 J / K; Loss B-UTA The data is measured in dB, representing the transmission loss on the interference link.

[0058] S4: Determine the interference avoidance instruction based on the interference avoidance strategy.

[0059] S5: The interference avoidance command is sent to the target satellite of the target constellation system through the target power station of the target constellation system, so that the target satellite performs interference avoidance action.

[0060] In this embodiment, based on the determined interference avoidance strategy for each feeder link, explicit interference avoidance instructions can be generated and sent to the target feeder station or target satellite of the feeder link, thereby causing the target feeder station or target satellite to perform specific interference avoidance actions. Interference avoidance instructions may include disconnecting the feeder link, establishing a new feeder link with another object, adjusting the transmission power, etc.

[0061] In some embodiments, the power supply link planning method further includes: receiving and storing the feedback signal from the target satellite; updating the link parameters based on the feedback signal; and redetermining the link score and the interference avoidance strategy using the updated link parameters.

[0062] Specifically, after performing interference avoidance actions, the target satellite can send a feedback signal. Based on the feedback signal, the attribute information of the newly established or modified feeder links of the target satellite can be determined, and a new round of interference avoidance strategies can be formulated. In this way, each feeder link of the target satellite system can be dynamically managed, ensuring that the overall communication quality and resource utilization of the target satellite system are maintained at a high level.

[0063] Please see Figure 3 and Figure 4 The power supply link planning method provided in one embodiment of this disclosure can be executed by a ground management unit and may include the following multiple processes.

[0064] Step 1: Set up an interference avoidance link planning platform in the ground management unit. The interference avoidance link planning platform can acquire and process the link parameters of multiple feeder links of the target constellation system (corresponding to step S1 above).

[0065] Step 2: Based on the optimal strategy for link planning, the interference avoidance link planning platform performs interference avoidance requirement analysis for each feeder link according to the satellite on-board time (for example, accurately assess the interference avoidance requirements of each feeder link through link scoring), including but not limited to reducing power, shutting down the link, switching the link, etc. (corresponding to step S2 above).

[0066] Step 3: Based on the interference avoidance requirement analysis, the interference avoidance link planning platform generates the corresponding interference avoidance instructions (corresponding to steps S3 and S4 above).

[0067] Step 4: The interference avoidance link planning platform sends the generated interference avoidance instructions to the bearer network, and then uploads them to the satellite's on-board processing payload through the network interface (corresponding to step S5 above).

[0068] Step 5: The onboard processing payload controls the satellite to perform interference avoidance actions according to the interference avoidance command.

[0069] Step 6: The interference avoidance link planning platform receives the interference avoidance execution response returned by the on-board processing payload. The response result can indicate whether the satellite has successfully executed the interference avoidance action.

[0070] In this embodiment, when the satellite system reaches a specific location, the feeder link needs to perform interference avoidance actions. At this time, the satellite system will implement interference avoidance based on a certain strategy. The ground management unit is the control center of the target satellite system. It can calculate the interference avoidance strategy in advance based on ephemeris information and carry out intelligent resource allocation planning based on this. Through the bearer network transmission line, the protocol gateway parses the interference avoidance command indicated by the interference avoidance strategy and transmits it uplink to the satellite through the feeder station on the feeder channel. The satellite's onboard processing payload processes and implements the interference avoidance command.

[0071] Please see Figure 5 In some implementations, an interference avoidance link planning platform can be set up at the ground management unit to receive response feedback information from the satellite after it receives interference avoidance commands. Based on the response feedback information, the interference avoidance link planning platform can perform an effectiveness evaluation on the adjusted target satellite system. The specific process can be as follows.

[0072] Step 7: Store and record the response status of each feedback electrical link (L1, L2, ..., Ln) to the interference avoidance command, and query the latest communication quality, link establishment time, resource allocation and other parameters of each feedback electrical link.

[0073] Step 8: Within a certain time window, prioritize the parameters queried in Step 7, and repeatedly record and deduce each parameter using the preset machine learning model in the interference avoidance link planning platform, and obtain a comprehensive score.

[0074] Step 9: Utilize the evaluation strategy of the interference avoidance link planning platform to evaluate the link planning effectiveness of each feeder link.

[0075] Step 10: The target satellite system optimizes the link planning based on the performance evaluation results.

[0076] This disclosure provides a technical solution through one or more embodiments, which can acquire link parameter information of multiple feeder links of a target constellation system, perform overall planning, and formulate interference avoidance strategies applicable to each feeder link. Based on the link parameters, a link score for each feeder link can be determined, thereby scientifically and effectively determining the necessity and priority of adjustments for each feeder link. Based on the interference avoidance strategy, interference avoidance instructions are determined and sent to the target satellites, instructing different satellites to perform optimized interference avoidance actions. In this way, the interference problem caused by the feeder links of the target constellation system to other constellation systems is solved, while also ensuring the communication quality within the target constellation system.
