Abstract
The method of rotating the IMU to improve the performance of system accuracy and design the SINS/GPS integrated systems are presented. The error of the rotation unit and the time asynchronous for the sake of GPS measure delay are analyzed. A H∞ filter approach based on the minimax criterion is proposed to deal with the alignment of SINS on moving base. Comparing the performance of Kalman filter and H∞ filter through digital simulation, this method shows that is makes initial alignment more quickly and prssesses such characters as high accurate and robustness.
