According to circumstance of sub-orbital vehicle re-entry flight segment, this paper designed a fault tolerant integrated navigation system consisted of INS/GPS/CNS. This system can determine different sensors combination scheme according to flight phases of sub-orbital vehicle, and realize information fusion of different sensors which are running without fault. The results of simulation show that designed navigation system has a favorable fault-tolerance feature and greatly improves the precision of navigation for sub-orbital vehicle in re-entry flight segment.
