A Design Method of High-fidelity Simulation System Based on Fault Diagnosis on Small Satellite Platform

摘要

The research for enhancing the operational reliability of spacecraft has become a hot topic in spaceflight fields in recent years.In this paper,a high-fidelity simulation platform was put forward for small satellites based on an all-digital and semi-physical simulation environment.On this platform,the performances of small satellites on CAST968 and CAST2000 can be simulated,the emersion of satellite flight course can be implemented based on Remote Control Command input,the maintenance methodology and maintenance scheme can be tested about fault emulation,and the simulation results can be presented.In this paper,the design method of the hardware and software of the simulation system was provided.The algorithm of fault setting and fault retrieval was derived at last.
