[0002] Digital satellite technology can simulate the entire life cycle of a physical satellite. Especially after the satellite is launched into orbit, it can simulate various real actions in orbit, thus providing strong support for the development of physical satellites and on-orbit missions.

[0003] Most existing digital satellite models are centralized, with the satellite service model, standalone model, and environmental model all contained within a single program. This creates a strong coupling, making it difficult to efficiently support standalone models for semi-physical simulation of physical satellites. Distributed digital satellite models, in which the satellite service model, standalone model, and environmental model operate independently, can effectively address the shortcomings of centralized digital satellite models. However, distributed digital satellite models have a large number of components, necessitating the design of a structure or method to enable information exchange between these components.

[0037] The distributed digital satellite model's satellite service model, standalone model, and environmental model operate independently, avoiding the overly coupled nature of centralized digital satellite models.

To address this information exchange issue in the distributed digital satellite model, the present invention provides a satellite interface platform that enables information exchange between the standalone model, satellite service model, and environmental model. Furthermore, in one embodiment of the present invention, the satellite service model is incorporated into the satellite interface platform as an interface, further simplifying the overall architecture of the distributed digital satellite model.

[0038] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings of the embodiments.

[0039] Figure 1 FIG. 1 is a schematic diagram showing the structure of a satellite interface platform for a digital satellite model according to an embodiment of the present invention. Figure 1 As shown, a satellite interface platform for a digital satellite model includes a satellite service interface 101, a measurement and control, ground measurement and response module 102, and a stand-alone interface module 103. The measurement and control, ground measurement and response module 102 and the stand-alone interface module 103 are communicatively connected to the satellite service interface 101, thereby enabling information exchange between the satellite service model and the stand-alone model, and connecting the stand-alone model and the satellite service model during the entire operation of the digital satellite model.

[0040] As previously mentioned, in one embodiment of the present invention, the satellite service model is included in the satellite interface platform in the form of an interface, namely, the satellite service interface 101. Specifically, the satellite service interface 101 also includes a satellite service processing component, which is used to simulate satellite service functions. For example, it can process remote control commands and telemetry data to generate telemetry and remote control information such as telemetry, ground measurement, telemetry requests, and stand-alone commands. In one embodiment of the present invention, the satellite service interface 101 is used to receive ground remote control commands and stand-alone telemetry data. The satellite service processing component, namely, the satellite service software, then performs computational processing on these data, outputting the telemetry and ground measurement data to the measurement and control / ground measurement response module 102, and outputting stand-alone commands and telemetry requests to the stand-alone interface module 103.

[0041] The TT&C / Ground Measurement Response Module 102 is communicatively connected to the ground test system 001 and the satellite service interface 101, and is used for information exchange between the ground test system 001 and the satellite service interface 101. The ground test system 001 receives and processes telemetry and ground measurement data, and sends instructions to the TT&C / Ground Measurement Response Module 102. Figure 2 FIG1 shows a schematic diagram of the structure of the measurement and control and ground measurement response module according to an embodiment of the present invention. Figure 2 As shown, in one embodiment of the present invention, the measurement and control, ground measurement response module 102 includes a command processing submodule 121 and a telemetry processing submodule 122. The command processing submodule 121 is configured to receive commands sent from the ground test system 001 to the digital satellite model, process them, and then transmit them as parameters to the satellite service interface 101. The telemetry processing submodule 122 is configured to receive telemetry and ground measurement signals output by the satellite service interface 101, process them, and then transmit them to the ground test system 001 for processing and display, thereby enabling information exchange between the ground test system 001 and the satellite service interface 101.

[0042] The stand-alone interface module 103 is communicatively connected to the stand-alone model 002 and the satellite service interface 101, and is used for information exchange between the stand-alone model 002 and the satellite service interface 101. The stand-alone interface module 103 is responsible for outputting initialization, triggering, telemetry requests, stand-alone instructions, and other information to the stand-alone model 002, receiving the return results after the stand-alone model 002 processes the telemetry requests, and then processing and organizing them into stand-alone telemetry for the satellite service interface 101 and sending them to the satellite service interface 101. Figure 3 FIG. 1 is a schematic diagram showing the structure of a stand-alone interface module according to an embodiment of the present invention. Figure 3 As shown, in one embodiment of the present invention, the stand-alone interface module 103 includes a configuration loading submodule 131, a telemetry request processing submodule 132, a trigger processing submodule 133, and an instruction processing submodule 134. When the stand-alone interface module 103 is started, the configuration loading submodule 131 loads the stand-alone model configuration and sends initialization information to the stand-alone model 002. The telemetry request processing submodule 132 is configured to receive the stand-alone telemetry request for the current time sequence output by the satellite service interface 101, obtain the stand-alone telemetry of the corresponding stand-alone model, and use it as the stand-alone telemetry input of the satellite service interface 101 at the next time sequence. The trigger processing submodule 133 triggers the stand-alone model 002 once at the current time sequence. The instruction processing submodule 134 is configured to receive the stand-alone instruction output by the satellite service interface 101 and transmit the stand-alone instruction to the corresponding stand-alone model for response. The response result is generally reflected in the stand-alone telemetry transmitted by the stand-alone model 002 to the stand-alone interface module 103.

[0043] Based on the satellite interface platform as described above, Figure 4 A flow chart showing an information interaction method for a digital satellite model according to an embodiment of the present invention is shown as follows: Figure 4 As shown, a method for information interaction of a digital satellite model includes:

[0044] First, in step 401, the platform is started. The satellite interface platform is started, and after the satellite interface platform is running, the measurement and control, ground measurement response module 102, and the stand-alone interface module 103 are started in sequence. Subsequently, the platform enters an infinite loop and sequentially executes the following steps:

[0045] In step 402, stand-alone telemetry is received. The stand-alone interface module 103 receives the return result of the telemetry request processed by the stand-alone model 002, and processes and organizes the result into stand-alone telemetry for the satellite service interface 101.

[0046] In step 403, the command is received. The command registered on the ground test system 001 is obtained through the measurement and control and ground measurement response module 102;

[0047] In step 404, the satellite service interface 101 is called. The satellite service interface 101 is called, and the single-machine telemetry and instructions are input into the satellite service interface 101 as parameters for processing. After the satellite service interface 101 is called, the telemetry, ground measurement, instructions, and telemetry requests to be processed are transmitted.

[0048] In step 405, the telemetry and ground measurement are processed. The measurement and control, ground measurement response module processes the telemetry and ground measurement data after receiving them, and transmits the processed data to the ground test platform 001; and

[0049] In step 406, the telemetry request and instruction are sent. The stand-alone interface module 103 transmits the trigger information, telemetry request, and instruction to the corresponding stand-alone model 002, and returns to step 402 to receive the return result of the telemetry request processed by the stand-alone model 002, and processes and organizes it into stand-alone telemetry for the satellite service interface 101.
