摘　　要：针对亚轨道飞行器再入飞行段的环境特性,设计了由INS、GPS、CNS组成的容错型组合导航系统,该系统能根据不同飞行阶段选择相应的传感器组合方案,将处于运行状态且无故障的子系统信息自动地实现最优融合。仿真结果表明,所设计系统具有良好的容错性,并达到了较高的导航精度。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.
