Description

Technical Field

[0001] This application relates to the field of wireless communication technology, and in particular to a satellite management method, a ground control center, a storage medium, and a computer program product. Background Technology

[0002] Low Earth orbit (LEO) satellites operate at a low altitude, typically between 500 and 2000 kilometers above the Earth's surface, enabling them to provide services with low latency. Because of their low altitude, the coverage area of ​​a single LEO satellite is relatively small, thus requiring a large constellation of satellites to achieve global coverage.

[0003] Currently, the management and control of low-Earth orbit (LEO) satellites mainly relies on ground control centers, such as direct communication between ground gateway stations and LEO satellites. Figure 1 As shown. However, due to the extremely high speed of low-Earth orbit (LEO) satellites, ground gateway stations need to frequently switch with different LEO satellites to maintain communication link continuity. This places an excessive burden on ground gateway stations, resulting in low real-time performance and efficiency. Furthermore, the global deployment of ground gateway stations is constrained by multiple factors, including geography, politics, and economics, making them susceptible to ground-based interference sources such as electromagnetic interference and terrain obstruction, as well as atmospheric conditions. This can even lead to situations where connections with LEO satellites cannot be established, making real-time control impossible. For these reasons, ground-based control has significant limitations, resulting in poor overall performance and reliability of the satellite network. Summary of the Invention

[0038] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0039] The technical solutions of this application and how they solve the aforementioned technical problems will be described in detail below through embodiments and in conjunction with the accompanying drawings. The embodiments below can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0040] Furthermore, the technical solutions described in the embodiments of this application can be combined arbitrarily without conflict.

[0041] This application provides a satellite management method in which a ground control center manages a group of low-Earth orbit satellites by deploying control nodes located in the air. The relevant management architecture is as follows: Figure 2 As shown. The satellite control method provided in the embodiments of this application is described in detail below.

[0042] Figure 3 This is a flowchart illustrating a satellite control method provided in an embodiment of this application. Figure 3 As shown in the embodiments of this application, the satellite control method mainly includes the following steps:

[0043] S101. Deploy at least one control node; wherein each control node is located in the air and has low-orbit satellites deployed within its coverage area, and the coverage areas of different control nodes are different.

[0044] In embodiments of this application, the ground control center may deploy at least one control node.

[0045] It should be noted that, in the embodiments of this application, the control node can be a medium-high Earth orbit satellite or a space station, that is, a location deployed in geostationary orbit or medium Earth orbit, or an independently operating space station, specifically located among low Earth orbit satellites, possessing powerful communication, computing, and storage capabilities. Of course, the control node can also be certain low Earth orbit satellites or unmanned aerial vehicles (UAVs). The specific hardware entity of the control node can be selected according to actual needs and application scenarios, and this application embodiment does not impose any limitations.

[0046] In an embodiment of this application, the deployment of at least one control node by the ground control center includes: deploying at least one control node with first information as the optimization target; wherein the first information includes at least one of the following: load difference of control nodes, propagation delay between control nodes, propagation delay between control nodes and low-orbit satellites, network unreliability of control nodes, and deployment cost.

[0047] It should be noted that, in the embodiments of this application, a deployment scheme is proposed with at least one of the following as optimization objectives: load difference of control nodes, propagation delay between control nodes, propagation delay between control nodes and low-Earth orbit satellites, network unreliability of control nodes, and deployment cost. This is because: load difference of control nodes affects network response time and service capacity, requiring consideration of how to balance the load based on service traffic and control frequency to ensure that all low-Earth orbit satellites receive reasonable resource allocation and avoid some control nodes being overloaded while other nodes are idle; propagation delay of control nodes and propagation delay between control nodes and low-Earth orbit satellites affect data transmission efficiency, requiring consideration of how to minimize these delays through routing optimization and signal processing techniques; considering the complexity of the space environment, network unreliability of control nodes is an important consideration, requiring consideration of how to improve network reliability through redundant design, error detection, and correction mechanisms; and the cost of satellite manufacturing, launch, and operation and maintenance needs to be considered when selecting the number of control nodes with control functions to deploy.

[0048] It is understood that, in the embodiments of this application, considering the distribution and operational needs of low-Earth orbit satellites, appropriate control nodes are selected for deployment. The location and number of control nodes can be determined through optimization algorithms to ensure that they can cover low-Earth orbit satellites globally, while reducing costs and improving efficiency, minimizing the deployment cost of control nodes, and meeting the coverage requirements for low-Earth orbit satellites.

[0049] It should be noted that, in the embodiments of this application, the first information may include one or more of the above items, that is, a single item may be used as the optimization target, or multiple items may be combined as the optimization target. The embodiments of this application do not limit this.

[0050] In the embodiments of this application, taking the first information including the above items as an example, the ground control center uses the first information as the optimization target to deploy at least one control node, including: selecting a location in the air based on the network topology; assuming that a control node is deployed at each selected location, evaluating the propagation delay between each control node and different low-orbit satellites, the propagation delay between different control nodes, and the network unreliability of each control node; combining the selected locations, and for each combination, assuming that a control node is deployed at each location in the combination, evaluating the load and deployment cost of the control nodes; selecting the optimal combination based on the evaluation information, and deploying a control node at each location in the selected combination.

[0051] For example, in an embodiment of this application, taking a small number of high-orbit satellites as control nodes as an example, the deployment of control nodes can be achieved through the following steps:

[0052] 1. Based on the network topology, select several possible locations for deploying control nodes (high-orbit satellites) (such as the network center node, near important nodes, etc.). For each location, calculate its propagation delay with all low-orbit satellite nodes; optionally, further calculate the average propagation delay.

[0053] 2. Within the range of deployable high-orbit satellites, try different combinations of numbers. For each combination, use heuristic algorithms (such as genetic algorithms, simulated annealing, etc.) to determine different location combinations; evaluate the load of deploying control nodes (high-orbit satellites) according to each combination (use standard deviation to measure load differences);

[0054] 3. Assuming that each selected satellite is deployed with one control node, evaluate the propagation delay between control nodes and the propagation delay between control nodes and different low-Earth orbit satellites;

[0055] 4. Assuming that each selected satellite is deployed with a control node, assess the network unreliability. A reliability coefficient can be introduced and adjusted based on historical data or simulation results.

[0056] 5. For each combination, assuming one control node is deployed at each location in the combination, evaluate the deployment cost, including control system cost, connection establishment cost, etc.

[0057] 6. Select the optimal combination based on comprehensive indicators (such as load balancing, latency, reliability, and cost evaluation results) and deploy the control nodes.

[0058] It should be noted that, in the embodiments of this application, the control node can reuse existing medium- and high-orbit satellites or space stations. In this case, when selecting a location in the air based on the network topology, a small number of locations of medium- and high-orbit satellites or space stations can be selected, then location combinations can be performed and a combination can be selected. Finally, the control node is deployed, that is, the relevant configurations for the medium- and high-orbit satellites or space stations at the selected locations are performed as control nodes. The control node can also be a drone. In this case, when selecting a location in the air based on the network topology, the desired location for deploying the control node can be selected, then location combinations can be performed and a combination can be selected. Finally, the control node is deployed, that is, the drone is dispatched to the location in the selected combination and configured as a control node. The specific node deployment can be implemented based on implementation requirements and application scenarios, and this application embodiment does not limit it.

[0059] S102. Low-orbit satellite control is carried out through at least one control node.

[0060] In the embodiments of this application, after deploying at least one control node, the ground control center performs low-orbit satellite control through the deployed at least one control node.

[0061] In the embodiments of this application, the ground control center and various management nodes work together to manage and control low-Earth orbit (LEO) satellites. The ground control center is responsible for receiving and processing data from LEO satellites, such as remote sensing data and communication data, and generating control commands. Each management node is responsible for sending control commands to LEO satellites and collecting satellite information from LEO satellites, and then sending this information to the ground control center. To improve the real-time performance and reliability of the management nodes, multiplexing and multiple access technologies, such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), and Code Division Multiple Access (CDMA), can be used to achieve efficient communication with LEO satellites.

[0062] Based on the above, the following details how a ground control center manages low-orbit satellites through at least one control node.

[0063] In the embodiments of this application, the ground control center manages low-Earth orbit satellites through at least one control node, which may include: collecting satellite information of low-Earth orbit satellites within different coverage areas through different control nodes of at least one control node.

[0064] It should be noted that, in the embodiments of this application, the low-Earth orbit (LEO) satellites are deployed in low Earth orbit and are responsible for specific communication, navigation, remote sensing, and other tasks, and are controlled by the control nodes. The ground control center, as a backup and auxiliary control center, is responsible for the overall planning and scheduling of the system, including itself, the control nodes, and the LEO satellites, as well as communication with the control nodes. The ground control center collects satellite information from the LEO satellites through at least one control node. That is, each control node collects satellite information from LEO satellites within its coverage area, such as operational data (remote sensing data), communication data, and status information. The status information includes, but is not limited to, position, velocity, attitude, and energy status. The ground control center receives the satellite information collected by each control node.

[0065] In embodiments of this application, the ground control center manages low-Earth orbit satellites through at least one control node, and may further include: sending control commands to a first low-Earth orbit satellite through a first control node among the at least one control node; wherein the first low-Earth orbit satellite is located within the coverage area of ​​the first control node, and the control commands are used to control the first low-Earth orbit satellite.

[0066] It should be noted that, in the embodiments of this application, the ground control center can generate control commands for a specific low-orbit satellite, such as the first low-orbit satellite. The control commands can be based on satellite information, mission requirements, or other constraints, such as a certain low-orbit satellite needing to perform a certain task at a certain time. The specific method of generating control commands is not limited in the embodiments of this application.

[0067] It should be noted that, in the embodiments of this application, the first low-orbit satellite is located within the coverage area of ​​the first control node. Based on this, the ground control center can send control commands to the first control node to control the first low-orbit satellite, and the first control node will then send the control commands to the first low-orbit satellite.

[0068] In the embodiments of this application, referring to the above description, the ground control center manages low-Earth orbit (LEO) satellites through at least one management node. This involves communication between the ground control center and each management node, as well as communication between each management node and the LEO satellites within its coverage area. Therefore, relevant links need to be established to support communication. Specifically, inter-satellite links are used for communication between each management node and the LEO satellites within its coverage area. Laser communication or microwave communication technologies can be used to improve data transmission rate and bandwidth. Simultaneously, to improve the reliability of inter-satellite links, multipath transmission and self-healing network technologies can be employed, such as multi-hop routing, network coding, and self-organizing networks. Satellite-to-ground links are used for communication between each management node and the ground control center. Laser communication or microwave communication technologies can be used to improve the stability and security of data transmission. Simultaneously, to improve the efficiency of satellite-to-ground links, data compression and data fusion technologies can be employed, such as image compression, video compression, and data fusion, to reduce data transmission bandwidth and time.

[0069] It should be noted that, in the embodiments of this application, the transmission of control commands differs from ordinary service data transmission. For a control node, after establishing a link with the low-Earth orbit satellites within its coverage area, the majority of transmissions are control commands, with service data transmitted only when necessary. This link can be established as needed by the ground control center. Furthermore, to ensure high-priority transmission of control commands, redundant backup paths or channels can be set up for them. For example, a dual-link connection method with satellite optical communication as the primary and microwave communication as the backup can be used to ensure that control commands can quickly switch to the backup path or channel for transmission when the primary path or channel fails. When control commands and service data are transmitted on the same link and inter-satellite link congestion occurs, a congestion management algorithm is used to prioritize the transmission of control commands. For example, a priority-based discarding strategy can be used to discard low-priority service data when necessary to ensure the smooth transmission of control commands.

[0070] In the embodiments of this application, considering the dynamic nature of satellite networks, the ground control center may also perform the following steps: adjusting the communication strategy of at least one control node based on mission requirements and / or satellite information of low-Earth orbit satellites collected through at least one control node.

[0071] It should be noted that, in the embodiments of this application, the ground control center can determine the operational status and ephemeris of the low-Earth orbit satellites based on the collected satellite information, and can predict their availability and duration. In addition, if the deployed control nodes are in a mobile state, their operational status can be monitored. Then, based on the operational status of the control nodes, the low-Earth orbit satellites, and the prediction results, the communication strategies of each control node, such as communication frequency, bandwidth allocation, and data transmission path, can be adjusted to ensure the availability, reliability, and security of data transmission between each control node and the low-Earth orbit satellites.

[0072] It should be noted that, in the embodiments of this application, the ground control center can use the collected satellite information, including parameters such as orbital inclination, right ascension of the ascending node, perigee angular distance, and average motion speed, to analyze the operating status of high-orbit and low-orbit satellites, such as their position, speed, attitude, and energy status, and predict their future trajectory and position.

[0073] It should be noted that, in the embodiments of this application, the ground control center adjusts the communication strategy of at least one control node, including but not limited to adjusting the communication strategy of all control nodes and adjusting the communication strategy of some control nodes. The adjustment methods include but are not limited to optimizing communication frequency, bandwidth allocation, data transmission path, and optimizing the use of inter-satellite links and satellite-to-ground links to reduce propagation delay and improve communication efficiency.

[0074] In the satellite management and control method provided in this application, the ground control center can generate control commands for any low-Earth orbit (LEO) satellite and distribute them to the LEO satellite through the management and control node to which the LEO satellite belongs; each LEO satellite can receive and execute the control commands and simultaneously report its own satellite information to its respective management and control node; each management and control node monitors the satellite information of LEO satellites within its coverage area in real time and performs resource scheduling and fault handling as needed; the ground control center performs overall analysis and optimization adjustments based on the satellite information collected through each management and control node.

[0075] The satellite management and control method provided in this application enables refined management and control of low-Earth orbit (LEO) satellite constellations, improving the overall performance and reliability of the satellite network. Furthermore, it considers the dynamic nature of the satellite network, adapting to changes in network topology and fluctuations in mission requirements. Specifically, through the wide coverage and strong communication capabilities of the management and control nodes, efficient management and control of LEO satellite constellations is achieved, reducing the burden on ground control centers and improving management and control efficiency. The low communication latency between the management and control nodes and LEO satellites enables real-time monitoring and rapid response, enhancing real-time performance. High-precision orbit determination and prediction technologies improve the orbit determination accuracy and orbit prediction accuracy of LEO satellites, providing a reliable basis for management and control and improving precision. A multi-layered security protection system is established to ensure the security and stability of the management and control system, enhancing security.
