As the most important index, the navigation accuracy and reliability is used to measure the performance of FOG vehicle integrated navigation system. In the foundation of federated filter and systematic accident diagnose algorithms, a novel integrated navigation filtering algorithm is designed based on FOG SINS(Fiber Optic Gyroscope Strapdown Inertial Navigation System)、GPS(Global Positioning System)、DR(Dead Reckoning). The simulation results show that the federated filter with failure detection can make full use of information from navigation sensor, and can isolate fault sources effectively, its accuracy and reliability are better than the generalized filters’.
