| Abstract: | This paper presents a new Kalman filter algorithm based on MIMU/GPS integrated navigation system. The system adopts MEMS IMU as the core of sensor. The position difference and the velocity difference between INS and GNS is as measurements, and the parameters is estimated using the measurement noise automatic weight Kalman filter. The results of simulation under MATLAB show that the algorithm is adaptive to the error of model and measurement noise covariance with high effectiveness and accuracy. |
