| Abstract: | Based on the basic principles of SINS / GPS integrated navigation system pure error of inertial navigation system is analyzed and the integrated navigation system error model is established,which is designed for the high reliability and is easily to achieve a simplified Kalman filter and the corresponding data fusion algorithms. And dynamic experiments for the navigation system has been done. Experimental results showthat navigation can effectively inhibit the navigation parameter errors and improve navigation accuracy. |
