Abstract
To improve the anti-interference ability of initial alignment, mean algorithm and Kalman filter algorithm for initial alignment are compared, and a data-reuse method for combining these two algorithms is proposed. One group of sampling data is reused for coarse and fine alignment, prolonging the coarse alignment time and making off-line algorithms aviable for fine alignment. The method was applied in a strapdown system, and experimental results show that the method can effectively restain the passanger disturbance.
