摘要
针对SINS/GPS/DVS全源组合导航系统在非理想状态下的容错性差,无法实现多源组合导航系统最优化的问题,建立基于卡尔曼滤波器的导航子系统局部滤波器和基于联邦滤波器的全源导航系统全局滤波器,设计了一种全源容错组合导航系统。通过仿真验证,该全源导航系统能够在子系统出现故障的情况下实现高精度导航,满足临界空间飞行器对导航系统精度和可靠性的要求。
In view of the poor fault tolerance of the SINS/GPS/DVS full-source integrated navigation system under non-ideal conditions,and the inability to optimize the multi-source integrated navigation system,a Kalman filter-based local filter for the navigation subsystem and a federation are established.The global filter of the all-source navigation system of the filter has designed an all-source fault-tolerant integrated navigation system.The simulation verification shows that the all-source navigation system can achieve high-precision navigation in the case of subsystem failures,and meet the requirements of critical space aircraft for the accuracy and reliability of the navigation system.
