In view of the poor fault tolerance of the SINS/GPS/DVS fullsource integrated navigation system under nonideal conditions, and the inability to optimize the multisource integrated navigation system, a Kalman filterbased local filter for the navigation subsystem and a federation are established. The global filter of the allsource navigation system of the filter has designed an allsource faulttolerant integrated navigation system. The simulation verification shows that the allsource navigation system can achieve highprecision navigation in the case of subsystem failures, and meet the requirements of critical space aircraft for the accuracy and reliability of the navigation system.
