| Abstract: | A multi-sensor navigation system composed of INS , GPS and Doppler was designed in this paper. An integrated system was established utilizing pseudo range, pseudo range rate and Doppler velocity. We construct the Kalman filter equation, design the flying profile, and then simulated the integrated system when the IMU performance is low. The simulation results bring out the conclusion that the multi sensor navigation system can greatly improve the navigation performance, depress the demand of the IMU . It points out the development direction of the navigation system. |
