The fault tolerant GNC system architecture for space station spacecrafts

Abstract

In this paper a fault tolerant GNC system architecture is studied. It presents a new architecture to meet the requirements of CHINA Space Station of two faults tolerant and long life. This robust GNC architecture with broadcast communications, wraparound technology and fault handle strategy greatly reduces the effects and occurrence of Byzantine disagreement. The simulation results of rendezvous and docking process indicate the validity of the fault tolerant system.
