Abstract: In view of the development needs of standardization and generalization of satellite simulation technology, a tool architecture is constructed that can support satellite digital simulation based on FMI (functional mock-up interface) and model reuse technology. On this basis, the satellite digital simulation platform is designed based on the idea of modularization, and the FMI standard wrapping method of Simulink and C/C++ model is given. Using the satellite digital simulation platform, the multi satellite operation simulation scene is built. Through the remote process call technology, the simulation process data is pushed to the visualization platform to complete the visual display of the satellite operation scene. The simulation case shows that the satellite simulation platform can monitor the operation state and change the trend of the model. At the same time, the scene visualization platform can dynamically display the operation orbit, attitude and other data of the satellite in real time.

Key words: FMI, modularization, satellite digital simulation platform, scene visualization
