[0016] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] The technical solution provided by the embodiments of the present invention is described in detail below with reference to the accompanying drawings.

[0018] As attached Figure 1 As shown, an embodiment of the present invention provides a three-dimensional simulation system for satellite motion state, the system comprising a control module 1 and a satellite motion simulation device 2, wherein: The control module 1 is used to receive the motion data of the satellite, and parse and convert the received satellite operation data into simulated flight parameters and flight instructions that can be recognized by the satellite motion simulation device 2. At the same time, the control module 1 digitally maps the satellite motion simulation device 2 to the actual satellite and the earth respectively, and constructs a virtual satellite and a satellite operation scene based on the digitally mapped satellite and the earth, and visualizes the three-dimensional motion state of the satellite simulated by the satellite motion simulation device 2; the satellite motion simulation device 2 is used to simulate the three-dimensional motion state of the satellite according to the flight parameters and flight instructions parsed and converted in the control module 1.

[0019] Specifically, in the satellite motion state three-dimensional simulation system of the present invention, the satellite motion simulation device 2 includes a drone 201, an earth model 202 and a support 203, wherein: The UAV 201 is used to receive the flight parameters and flight instructions of the control module 1 and simulate the operating status of the satellite; the earth model 202 is a scaled model of the real earth and is used to provide the UAV 201 with an environment for simulating the three-dimensional motion state of the satellite; the support 203 is used to fix the earth model 202.

[0020] With such arrangement, the operation of the UAV 201 is controlled by flight parameters and flight instructions converted based on the motion data of the satellite to realize the simulation of the satellite operation status. Moreover, since the earth model 202 is a real scaled model of the earth, when the UAV 201 moves around the earth model 202 under the flight parameters and flight instructions, it can truly and accurately reflect the operation status of the satellite, and there is no obstruction during the operation, and the three-dimensional motion process of multiple satellites in the whole orbital period can be visualized. At the same time, the space occupied by the equipment in the satellite simulation process is reduced as much as possible, which can greatly reduce the problem of blind spots in the movement of the satellite.

[0021] It should be noted that since the number of satellites in different usage scenarios and different usage states is different, when simulating the satellite motion state, one or more corresponding numbers of drones 201 are set according to the actual number of satellites, and the scaling ratio and size of the earth model 202 are determined according to the number of drones 201 and the actual application situation.

[0022] In order to make the UAV 201 easy to operate and to reduce the use cost, maintenance cost and the overall cost of the satellite motion state three-dimensional simulation system of the UAV 201, it is preferred to set the UAV 201 as a multi-rotor UAV.

[0023] In some optional implementations of the present embodiment, the support member 203 is a rod or frame with a certain hardness, which is non-deformable and non-retractable, such as a support rod, a bracket or a base. When simulating the three-dimensional motion state of the satellite, it can be fixed at the bottom, top or around the earth model 202 by contact or detachable connection. However, it should be noted that since the drone 201 needs to rotate around the earth model 202 after it is fixed, the selected support member 203, in addition to having a certain strength, also needs to occupy as little space as possible to prevent the arranged support member 203 from interfering with the flight of the drone 201.

[0024] In another optional implementation of this embodiment, the support member 203 is a rope, and the earth model 202 is fixed by hanging.

[0025] Specifically, in the satellite motion state three-dimensional simulation system of the present invention, the control module 1 includes a modeling module 101, an analysis module 102, a scene design module 103, a drone control module 104, a communication module 105 and a main control module 106, wherein: The modeling module 101 is wirelessly connected to the drone 201, and is used to receive the operating status data of the drone 201 in real time, and digitally map the drone 201 and the earth model 202 to the actual satellite and the earth respectively; the parsing module 102 is used to receive the motion data of the satellite, parse the operating status information of the satellite, and convert the satellite operating status into the flight parameters of the drone 201 in combination with the operating status data of the drone 201 received in real time by the modeling module 101; the drone control module 104 is connected to the parsing module 102, and is used to receive the satellite operating status information parsed by the parsing module 102 and convert it into instructions that the drone 201 can recognize, control the flight of the drone 201, simulate the three-dimensional motion state of the satellite, and feed back the flight status information of the drone 201 and the three-dimensional motion state information of the simulated satellite to the parsing module 102 and the scene design module 103; the scene design module 103 is connected to the modeling module 101 and the drone control module 104. The control module 104 is connected to the drone control module 104, which is used to build a virtual satellite and a satellite operation scene according to the satellite and the earth digitally mapped by the modeling module 101, and the three-dimensional motion state of the simulated satellite controlled by the drone control module 104 to fly the drone 201 is visualized in the scene design module 103. At the same time, the scene design module 103 converts the designed satellite motion into instructions recognizable by the drone 201 under the action of the parsing module 102 and the main control module 106, and transmits the converted instructions to the drone control module 104 to control the flight of the drone 201; the main control module 106 is respectively connected to the parsing module 102, the scene design module 103, the drone control module 104 and the modeling module 101, for integrated processing of the received information; the communication module 105 is connected to the drone control module 104, so that the drone control module 104 can perform two-way data transmission with the drone 201 through the communication module 105.

[0026] It should also be noted that in order to make the simulated three-dimensional motion state of the satellite more realistic and accurate, the acquired satellite motion data includes the actual operating state data of the satellite in orbit.

[0027] Specifically, the principle of the satellite motion state three-dimensional simulation system of the present invention is: By analyzing the actual motion data of the real satellite, the analyzed motion data is converted into flight parameters and flight instructions that the drone 201 can recognize and simulate, and the drone 201 is controlled to fly, so as to simulate the actual motion state of the satellite. At the same time, the flight state information of the drone 201 is fed back to the analysis module 102 and the scene design module 103, and the modeling module 101 is wirelessly connected to the drone 201 to receive the operation state data of the drone 201 in real time, and the drone 201 and the earth model 202 are digitally mapped to the actual satellite and the earth respectively, and a virtual satellite and a satellite operation scene are constructed according to the satellite and the earth digitally mapped by the modeling module 101, and the drone control module 104 controls the drone 201 to simulate the flight of the satellite. The three-dimensional motion state is visualized in the scene design module 103. At the same time, the scene design module 103 converts the designed satellite motion into instructions recognizable by the UAV 201 under the action of the analysis module 102 and the main control module 106, and transmits the converted instructions to the UAV control module 104 to control the flight of the UAV 201. When the UAV 201 moves around the earth model 202 under the flight parameters and flight instructions, it can truly and accurately reflect the operating state of the satellite, and there is no obstruction during the operation. The three-dimensional motion process of multiple satellites in the full orbital period can be visualized. At the same time, the space occupied by the equipment in the satellite simulation process is reduced as much as possible, which can greatly reduce the problem of blind spots in the movement of the satellite.

[0028] Second, as Figure 2 As shown, the present invention also provides a three-dimensional simulation method of satellite motion state using the above-mentioned three-dimensional simulation system of satellite motion state, comprising: Acquire the motion data of the satellite, and parse and convert the acquired motion data into simulated flight parameters and flight instructions that can be recognized by the satellite motion simulation device 2; use the satellite motion simulation device 2 to simulate the three-dimensional motion state of the satellite according to the flight parameters and flight instructions; receive the operating state data of the satellite simulated by the satellite motion simulation device 2 in real time, digitally map the satellite motion simulation device 2 to the actual satellite and the earth respectively, and construct a virtual satellite and satellite operating scene; according to the constructed virtual satellite and satellite operating scene, use a variety of different simulation modes to simulate the three-dimensional motion state of the satellite, and display it visually.

[0029] Specifically, in the above-mentioned three-dimensional simulation method of satellite motion state, the multiple different simulation modes include at least a simulation mode and a physical simulation mode. The simulation mode includes setting the satellite and the satellite motion state by simulation, and visualizing the satellite motion process. The physical simulation mode includes using the on-orbit satellite and satellite motion data to visualize the satellite motion process.

[0032] In combination with the above-mentioned satellite motion state three-dimensional simulation system, the three-dimensional motion state of the satellite is simulated by using the simulation mode, including the following steps: S01: Entering a simulation mode in the main control module 106; S02: Setting the satellite, satellite motion orbit, and satellite motion attitude information in the scene design module 103; S03: Using the scene design module 103 to read the digital mapping information of the satellite motion simulation part in the modeling module 101, converting the information set in step S02 into the number of drones 201 and flight trajectory information, and sending the converted information to the drone control module 104; S04: using the drone control module 104 to send the received information to the drone 201 through the communication module 105 to control the flight of the drone 201; S05: During the flight of the drone 201, the flight status information of the drone 201 is transmitted back to the main control module 106 step by step through the communication module 105 and the drone control module 104.

[0034] In combination with the above-mentioned satellite motion state three-dimensional simulation system, the three-dimensional motion state of the satellite is simulated by using the physical simulation mode, including the following steps: S11: Entering physical simulation mode in the main control module 106; S12: receiving and analyzing the motion state data of the on-orbit satellite in the analysis module 102; S13: Using the analysis module 102 to read the digital mapping information of the satellite motion simulation device 2 in the modeling module 101, Convert the information obtained by parsing in step S12 into the number and flight trajectory information of the drones 201, and send the converted information to the drone control module 104; S14: using the drone control module 104 to send the received information to the drone 201 via the communication module 105 to control the flight of the drone 201; S15: During the flight of the drone 201, the flight status information of the drone 201 is transmitted back to the main control module 106 step by step through the communication module 105 and the drone control module 104.

At the same time, the three-dimensional simulation method of satellite motion state of the present invention can also support multiple different simulation modes to simulate the three-dimensional motion state of the satellite and perform visual display.
