Description

Technical Field

[0001] The invention relates to a remote sensing satellite multi-satellite coordinated task automation test system and method, belonging to the technical field of remote sensing satellite autonomous task testing. Background Art

[0002] The intersatellite link subsystem can effectively reduce the limitation of the ground station's visible window on task execution, integrate and schedule the resources of multiple remote sensing satellites in the system, and realize the multi-satellite collaborative task of remote sensing satellites. The gradual enhancement of the intersatellite collaborative capability of remote sensing satellites has also put forward higher requirements for ground testing. On the one hand, due to the complexity of intersatellite collaborative scenarios and the need for certain conditions to carry out collaborative tasks, it is usually necessary to artificially simulate the orbital data of multiple satellites in advance and calculate the orbital visibility during ground testing, which leads to the limitations of ground test scenarios. Usually, several specific scenarios are used for multi-satellite collaborative task testing. Fixed test scenarios reduce the fault tolerance of each link in the test process. If any link in the test process fails to meet the requirements of the scenario design time, it needs to be restarted, which greatly reduces the test efficiency and brings many inconveniences to the comprehensive test of remote sensing satellites. On the other hand, intersatellite collaborative tasks involve multi-type and multi-channel interactive information. There are great difficulties in identifying the working status of each satellite in the scene and encoding, decoding and interpretation of the data transmission content of intersatellite interaction.

[0114] Example

[0115] like Figure 1 As shown, the present invention provides a remote sensing satellite multi-satellite collaborative task automation test system and method, the system consists of a process control system and a data satellite, and includes the following steps:

[0116] This invention is based on the simulation and deduction of digital satellites, and uses digital satellites to calculate the visibility and visible arc segments of the satellite and other satellites in the inter-satellite collaborative mission test scenario in near real time.

[0117] The rapid deduction results of the digital satellite provide input for the process control system in the present invention. The process control system classifies the multi-satellite collaborative tasks according to the feedback results of the digital satellite; for different types of intersatellite collaborative tasks, the collaborative task process is automatically executed according to the design arrangement logic, so as to send task-related remote control instructions to the satellite under test and set the task status for the ground simulator of other satellites.

[0118] 1. Design of multi-satellite collaborative test scenarios based on digital satellites

[0119] The multi-satellite collaborative mission is a collaborative effort between multiple high-orbit and low-orbit satellites, with inter-satellite links as information exchange channels to achieve mission guidance between high-orbit and low-orbit satellites. In order to verify the correctness of the on-board orbit visibility algorithm and the execution process of the multi-satellite collaborative mission, the multi-satellite collaborative mission conditions are designed based on the near-real-time simulation results of digital satellites before the collaborative mission test, and the simulated orbit visibility is compared with the orbit visibility calculated by the on-board software.

[0120] In order to quickly generate collaborative mission scenarios, the process control system establishes a connection with the digital satellite through a data interface. 10 minutes before executing the collaborative test mission, the local satellite time, six orbital numbers and target imaging area are sent to the digital satellite. The digital satellite uses the current satellite time, orbit and target area to simulate and deduce the visibility of the local satellite and other satellites to the target area in the future, determine the satellite selection rules, and return the satellite selection results to the process control system. The process control system selects the mission scenario as the local satellite guiding the low-orbit satellite collaborative mission or the low-orbit guiding the local satellite collaborative mission based on the visible arc of the local satellite and other satellites, and generates the mission configuration parameters. The specific test mission scenario design process is shown in the attached figure. Figure 2 shown.

[0121] 2. Automatic test method for the satellite-guided low-orbit satellite collaborative mission

[0122] For the collaborative mission of guiding low-orbit satellites from the local satellite, the process control system designs remote control ground inspection equipment according to the test scenario to simulate the operating status of the selected low-orbit satellite;

[0123] The selected low-orbit satellite orbit is added to the satellite under test, the link establishment status between local satellites is checked and the visible arc is calculated through telemetry, and the comparison result is obtained by comparing it with the feedback result of the digital satellite;

[0124] Determine whether the visual result is within the calculation error range; if so, the process control system will register the inter-satellite collaborative task on the local satellite remote control channel before the start of the visual arc according to the test scenario design parameters;

[0125] After the mission is launched, the process control system completes the working status setting of other cooperating subsystems of the satellite during the mission execution according to the editable execution logic;

[0126] After the visible arc begins, the information exchange packets between the subsystems on the satellite are detected, and after judging that the inter-satellite interaction conditions are met, the guidance information of the satellite is sent to the low-orbit satellite;

[0127] Confirm that the low-orbit satellite receives the guidance information correctly, and the satellite guides the low-orbit satellite collaborative mission. The automatic test process of the satellite guiding the low-orbit satellite collaborative mission is as follows Figure 3 shown.

[0128] 3. Automatic test method for low-orbit satellite-guided collaborative mission

[0129] For the low-orbit satellite guiding the satellite's collaborative mission, the process control system designs the remote control ground inspection equipment according to the test scenario to simulate the operating status of the selected low-orbit satellite, and registers the selected low-orbit satellite's orbit to the satellite;

[0130] Check the inter-satellite link status and calculate the visible arc through telemetry, and compare it with the feedback results from digital satellites;

[0131] After confirming that the visual results are within the calculated error, the process control system remotely controls the ground inspection equipment after the visual arc begins according to the test scenario design parameters;

[0132] Simulate low-orbit satellites to send mission guidance information to this satellite;

[0133] After the coordinated mission is launched through telemetry monitoring, the mission execution process is similar to the coordinated mission of guiding low-orbit satellites by the local satellite;

[0134] The process control system monitors the execution status of the satellite mission in real time until the satellite sends the guidance information to another low-orbit satellite, completing the automatic test of the low-orbit satellite guiding the satellite's collaborative mission. The specific process is as follows. Figure 4 shown.

[0135] 4. Process control system composition and operation process

[0136] The process control system consists of a data interface module, an information encapsulation module, a logic editing module, and an automatic test module. The data interface module is mainly used to establish data interaction with digital satellites and inter-satellite ground inspection equipment. Before carrying out multi-satellite collaborative tasks, the satellite time and orbit information is sent to the digital satellite through the data interface module. After the test scenario is determined, the ground inspection equipment is remotely controlled through the data interface module to cooperate with the satellite to complete the automatic test of multi-satellite collaborative tasks; the information encapsulation module is mainly used to combine and encapsulate various types of information interacting with the satellite and other satellites. Before use, various types of information formats need to be input as structured files. After reading, the information encapsulation module can automatically encapsulate related interactive data for use by other modules; the logic editing module is mainly used to edit the ground operation logic during the execution of collaborative tasks, and store the ground operation logic in a structured form; the automatic test module comprehensively schedules each module according to the design logic, obtains the test scenario through the data interface before testing, and during the test, sets the ground and on-board subsystems according to the test logic, and sends the interactive information to the inter-satellite ground inspection equipment according to the logic until the test logic is executed, completing the automatic test of the collaborative task.
