Design and Application of Simulation System Based on Digital Satellite
Aiming at the shortage of insufficient speedup ratio and universality of satellite digital simula-tion,a low coupling and high compatibility design method based on digital satellite simulation system is proposed in this paper.Under the overall structure of the simulation system,the function of the internal and external interfaces,virtual bus module,on-board stand-alone simulation strategy and the orbit simu-lation module,channel simulation module,and target simulation module in digital scene subsystem are analyzed and designed.The test and verification of the digital satellite simulation system developed under the method shows that the system has the capability to accelerate simulation at a speed with no less than 30 times and supports multiple satellites collaborative simulation,which can provide a reference for the design of subsequent satellite digital simulation systems.
