X. 收藏  |  浏览/下载：26/0  |  提交时间：2013/03/25 In order to improve the initial alignment accuracy and convergence rate of the SINS system  proposed the improved UKF algorithm (AUKF) based on the Unscented Kalman Filter (UKF). Noise statistical characteristics are mostly unknown in real systems  when it was effected by the initial value errors and dynamic model errors  AUKF algorithm can real-time adjust the covariance of the state vector and observation vector  and balance the right ratio of the state information and observation information in the filter results  thereby improving the system performance. The experimental results show: The Improved UKF Algorithm enhances the convergence speed and alignment accuracy effectively. 2011 IEEE.
