一种多飞行器协同的GNC系统飞行模拟平台设计OA北大核心CSTPCD

A method for designing simulation platform of the spacecraft Guidance Navigation&Control(GNC)sys-tem is proposed.During the in-space assembly and long term operation of the Chinese Space Station,complex flight missions are involved,including multi-spacecraft individual on-orbit flight,space rendezvous and docking,multi-spacecraft combination fusion control,separation process control and spacecraft re-entry.The integrate and realistic flight simulation is necessary and vital.Based on time synchronization,real-time data exchange,distributed and in-tegrated simulation architecture,a universal multi-spacecraft collaborative Hardware-in-the-Loop(HIL)simulation platform of GNC system is proposed,on which integrate flight simulation with high fidelity is possible to be a-chieved.The platform consists of several universal simulators,which are highly flexible and expandable,and each can be configured as any specific spacecraft and perform the spacecraft's whole mission process flight simulation in-dependently.The platform synchronizes time via IRIG-B code and exchanges dynamics data on 1553B bus in real-time,and multi-spacecraft co-simulation can be implemented after coordination accomplished among simulators.This simulation platform has been successfully applied in a spacecraft flight control drilling program.
