| Abstract: | In order to research the quality of GPS/INS integrated navigation system,this paper studied the simulation by using the real time experiment data of inertial navigation system and GPS. The integrated GPS/INS position, velocity, pesudorange and pesudorange rate have been simulated respectively. U D discompose algorithm is used to Kalman filter. In the end , the paper presents the position and the velocity curves of the inertial navigation system and the integrated navigation system .Simulation results and relative conclusion are provided. |
