Application of Adaptive Filtering Algorithm to Initial Alignment of Single-axis Laser Inertial Navigation System under Moving Base
Abstract：When the noise and noise measurement matrix are unknown in the initial alignment of single-axis laser inertial navigation system,it can decrease the filtering accuracy,or even make the filtering divergent.Considering above reasons,a simplified Sage-Husa adaptive filtering algorithm is proposed.Establish the error model of single-axis laser inertial navigation system under moving.We use the proposed algorithm to simulate.The simulation results show that the adaptive filtering algorithm can improve the accuracy and stability.
Keywords：single-axis laser inertial navigation systemadaptive filtering algorithm initial alignment
