| Abstract: | To meet the high reliability requirement of GNC system for aerospace vehicle (ASV),developing the GNC system architecture research based on the Byzantine failure mode.This architecture is based on four computer processing modules and three MIL-1553B data buses,The comparison of the IO data through the system bus based on multi-computers redundancy.Byzantine fault is avoided,and the system reliability is improved.The GNC system has the function of fault detection ,fault location ,fault isolation and fault self-healing.The architecture solves the high dynamic and strong interference environment problems of the poor autonomy system.In addition,the system architechture can meet On-orbit and Reentry requirements. |
