Application of Adaptive Kalman Filter Technique in Initial Alignment of Single-axial Rotation Strap-down Inertial Navigation System

摘要：

　　In order to improve the accuracy of initial alignment which determines the accuracy of navigation,a Sage-Husa adaptive kalman filter algorithm is applied to SINS initial alignment of single-axis rotation system.The simulation result further shows that in the case of inaccurate statistical property of noise,the estimation accuracy of Sage-Husa adaptive kalman filter is better than the conventional kalman filter.
