| Abstract: | A new disturbance resistance method for SINS initial alignment is proposed, which uses the active disturbance rejection technology. The error model of system is set up, the precision and vecolity of the aligning scheme is further researched. Both simulation and practical system test show that, compared with the Kalman filter, the proposed method is with the great capability of tracking the disturbance. It is an effective initial alignment scheme for SINS. |
