Abstract: This paper firstly summarizes and analyzes the developing status and requirement of spacecraft flight control simulation and parallel systems. In view of the current generalization and standardization of China’s spacecraft flight control simulation and parallel systems, an assemblable definition and system architecture of spacecraft flight control simulation and parallel systems is proposed. Then it elaborates on the design of two component simulation and verification, decision and support. The validity of the system is verified by the flight control of Chang’e 5. The paper finally gives a prospect of the future direction of spacecraft flight control simulation and parallel systems development.

Key words: Chang ’e 5 probe, Spacecraft flight control, Ground simulation, Parallel systems, Decision and support
