According to a combination navigation system of optical fiber IMU and GPS,because of the expansion of the scale system,the system complexity increased,the probability of system error inevitably increased on the dynamic system fault diagnosis,including the general approach,dynamic studies including fault diagnosis system in general,then two χ 2 methods were set up.They were used to SINS/GPS system on the basis of fault simulation analysis;Finally,based on a model of missile which used the fiber optic inertial measurement system and GPS navigation system for the composition of the background,data was obtained in the environmental testing algorithm for the simulation.The method is proved the feasibility of the algorithm and the correctness,and the research results have important reference value to design of navigation system reliability.
