[0035] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0036] The intelligent satellite hierarchical communication control system provided in the embodiment of the present application uses distributed software technology to abstract network functions, so that the network is no longer limited to the hardware architecture, and thus supports multiple software-defined intelligent satellites to efficiently orchestrate, reconstruct resources, and quickly and flexibly network according to business needs to perform customized tasks.

[0037] See also Figure 1 , showing a schematic diagram of an intelligent satellite hierarchical communication control system provided in an embodiment of the present application.

[0038] The intelligent satellite hierarchical communication control system performs dual-layer communication control on the first satellite constellation in the upper orbit and the second satellite constellation in the lower orbit. Specifically, the system includes an interaction layer, a control layer and a virtual execution layer, wherein:

[0039] The interaction layer further includes a user sensor and a communication interface (COMM.I / F) for communicating with a first communication network of a first satellite constellation and a second communication network of a second satellite constellation, acquiring satellite operation data and providing it to the virtual execution layer for processing;

[0040] The control layer further includes a flight control system and a propulsion navigation system, which are used to send control instructions to the intelligent satellite according to the processing results of the satellite operation data by the virtual execution layer, and perform flight control and propulsion navigation control on the intelligent satellite;

[0041] The virtual execution layer further includes an operating system, a storage system and a processing system, wherein the operating system includes each virtual node mapped by each intelligent satellite, and the storage system stores a first satellite constellation configuration file and a second satellite constellation configuration file; the processing system is used to parse the first satellite constellation configuration file, determine a first virtual node set corresponding to the first satellite constellation, and topological relationship information of each virtual node in the first virtual node set, and parse the second satellite constellation configuration file, determine a second virtual node set corresponding to the second satellite constellation, and topological relationship information of each virtual node in the second virtual node set, and, according to the satellite operation data, identify the constellation affiliation information of the intelligent satellite according to the topological relationship information of the virtual node, and control to allow or prohibit communication between the first satellite and the second satellite according to the task processing strategy, wherein the first satellite and the second satellite are: two satellites both from the first satellite constellation or the second satellite constellation, or two satellites from the first satellite constellation and the second satellite constellation respectively.

[0042] Among them, the constellation configuration file includes resource allocation information of each satellite in the constellation and the topological relationship between each satellite. For example, by parsing the first satellite constellation configuration file, the N intelligent satellites included in the first satellite constellation and the topological relationship between the N intelligent satellites can be determined according to the resource allocation information, such as the arrangement order and communication relationship of each intelligent satellite in the first satellite constellation.

[0043] During the task processing, it may be necessary for multiple satellites to cooperate with each other, and the multiple satellites may be from the same constellation or from different constellations. For example, assuming that for a specific task, satellite i and satellite j need to work together, at this time, the task processing strategy can be analyzed to control the communication between satellite j and satellite j, where satellite i and satellite j can be from the same constellation (for example, both from the first satellite constellation), or from different constellations (for example, satellite i is from the first satellite constellation, and satellite j is from the second satellite constellation).

[0044] See also Figure 2 , showing a schematic diagram of the intelligent satellite hierarchical communication link provided by an embodiment of the present application. In the embodiment of the present application, a satellite constellation is deployed in the upper orbit to form a first communication network; a satellite constellation is deployed in the lower orbit to form a second communication network, forming the simplest hierarchical communication mode. In this communication network, satellites in the upper and lower orbits can selectively communicate with each other through identification, deployment and allocation; and a communication network with a forward communication path and a reverse communication path can be configured to be established with the ground control system.

[0045] In the process of executing tasks, different tasks have different levels, such as grading from the perspective of difficulty, or grading from the perspective of importance, or grading from the perspective of urgency, or grading from multiple perspectives, etc. Accordingly, for tasks of different levels, it is necessary to select intelligent satellites (or intelligent satellite combinations) of corresponding levels for processing, such as selecting idle satellites for urgent tasks, or selecting satellites with higher resource allocation for difficult tasks, etc. Therefore, when selecting satellites for tasks and how to schedule satellites for multiple tasks, it is necessary to consider multiple technical aspects such as satellite role definition, quality evaluation of satellite execution tasks, resource scheduling and management, etc.

[0046] The following is a detailed description of several key technical points in the intelligent satellite hierarchical communication control system provided in the embodiment of the present application. Figure 3 , shows a schematic diagram of key technical points of an intelligent satellite hierarchical communication control system provided by an embodiment of the present application, and the three main technical points include quality evaluation technology, role definition technology, and resource allocation and management technology. The following are introduced respectively.

[0047] 1. Quality evaluation

[0048] Before executing a mission, it is necessary to identify satellites in one or more constellations that meet the conditions required to execute the mission, and to grade the quality of the satellites' mission execution. A satellite in the constellation executes a specified mission and transmits mission data to the backup satellite for verification and fault diagnosis. When the backup satellite diagnoses a fault, it terminates and replaces the mission satellite to execute that part of the mission, and at the same time calls the third satellite in the constellation as a backup satellite to verify and identify faults for that part of the mission.

[0049] It can be seen that in the quality evaluation, it is necessary to identify the satellites in one or more constellations that meet the conditions required to perform the target mission, and to grade the quality of the satellites performing the mission, and select the primary satellite and the backup satellite according to the grading results. Among them, the first primary satellite is determined to perform the specified mission, and the mission data is transmitted to the second backup satellite for verification and fault diagnosis. When the second backup satellite diagnoses a fault, the first main satellite is controlled to terminate the mission and use the second backup satellite to perform this part of the mission instead. At the same time, the third backup satellite is called to verify and identify the fault of the mission performed by the second backup satellite.

[0050] 2. Role definition and adjustment

[0051] Role definition can ensure the adjustment of tasks in orbit. The premise of satellite role adjustment is quality evaluation. On this basis, in order to manage the applications executed by each satellite, a scheduling table needs to be generated as the basis for calling each application and each application's access to user sensors. It is also the basis for realizing satellite resource integration calling. Role definition is bidirectional. The scheduling table is the basis for the satellite to call the application when the relevant mission requirements are met. At the same time, the user needs a basis for calling the satellite, so the attribute scoring metric is generated. The attribute scoring metric indicates the capability level of each satellite for at least some of the dedicated roles, which can help users select target satellite equipment. Users can be ground users or airborne users.

[0052] It can be seen that in the process of role definition and adjustment, a scheduling table needs to be generated for the virtual node corresponding to each smart satellite, which is used to record the operating status information of each smart satellite according to the satellite operating data, and determine whether the operating status information recorded in the scheduling table meets the requirements of the attribute scoring metric according to the pre-set attribute scoring metric, and set and / or update the role capability level for the smart satellite accordingly. Among them, the role capability level of the smart satellite can be displayed to the user, so that the user can select the smart satellite device corresponding to the target task according to the role capability level.

[0053] 3. Resource allocation and management

[0054] Resource allocation and management is the function of satellite allocation and management under the passive use of the inherent state of the constellation. When necessary, in order to expand the communication bandwidth and improve the mission quality, the satellite orbit is changed and the mission window is set, and the constellation satellite is adjusted to achieve pseudo-geosynchronous satellites.

[0055] It can be seen that satellite resource allocation can be carried out according to satellite operation data, driven by strategies to expand communication bandwidth or improve mission quality. Among them, the satellite orbit change operation is called to change the orbit of the target satellite, or to adjust the orbit height of the target satellite, or to adjust the distance between multiple target satellites.

[0056] In summary, the embodiments of the present application can realize communication links between satellites in the same orbit, communication links between orbital layers, and communication links between each orbital layer and the ground through the control of the intelligent satellite layered network. With the help of role allocation between constellation satellites and between constellations and constellation satellites, the functions of geosynchronous satellites can be pseudo-virtualized to solve problems such as tight geosynchronous satellite orbits, communication delays and high costs. At the same time, orbital layered communication technology enables satellites to be distinguished from traditional satellites in actual mission execution, and they have "elastic" capabilities such as dispersion, reorganization, and self-repair during mission execution.

[0057] See also Figure 4, showing a schematic diagram of an application scenario of an intelligent satellite hierarchical communication control system provided in an embodiment of the present application. Figure 4 In the scenario, a low-orbit satellite constellation is used to coordinate tasks with other higher-orbit constellations, or to serve as a relay satellite for higher-orbit constellations, or to perform part of the task to transmit data to higher-orbit constellations or ground command and control centers; low-orbit constellations receive and transmit mission information obtained by different sensors to airborne platforms such as drones, fighter jets, and airships according to mission requirements. In order to better play the role of software-defined architecture, a series of resource allocation and management evaluation indicators can be used to maximize mission requirements. Through satellite constellations equipped with software-defined architecture, pseudo-geosynchronous satellites and other functions can be realized through mission window settings, adjustment of satellite orbit height, and distance between satellites.
