摘要：

A new initial of alignment of Strapdown inertial navigation system (SINS) based on the fuzzy Kalman filter is proposed. Fuzzy logic has been incorporated to tune the system error covariance of the filter in the initial alignment process. The simulation results have shown that the using of fuzzy Kalman filter for initial alignment can improve the consistency of the filter and the estimation accuracy. In the meantime the alignment time is reduced considerably.
