The system designed of dynamic filter to get dynamic filtering result by integrating the GPS and dynamics model of inertial navigation system using Kalman filtering principle. Then the system got the final state vector sequence by integrating dynamic filtering result and the Beidou navigation system using the sequential adjustment principle. The result about numerical simulation of integrated navigation system show that on the one hand bination can solve the poor dynamic performance and poor anti-interference ability problem of single satellite navigation system; on the other hand, solve the accumulation of inertial navigation error and large drift problem of single inertial navigation. At the same time, adding the Beidou navigation system improves the safety of navigation system.
