Design and Simulation of an Improved Five Redundancy GNC System Architecture

Article Preview

Abstract:

Aerospace plane, the next generation manned spacecraft has the characteristics of high reliability and high security. Therefore, a five modular redundancy byzantine fault tolerant architecture is propose for the guidance, navigation and control (GNC) system. This architecture can give the system characteristic of double fault resilience, and is also suitable for solving Byzantine general problem. A semi-physical simulation is done, which is based on 1553B data bus and VxWorks operating system. The simulation result has verified the fault tolerant architecture and feasibility of the system implementation.
