摘要
Abstract
Linear error model of SINS can't work under large heading error, but a coarse alignment decreasing the heading error to a small angle will make the alignment time-consuming.To avoid the problem, a multiple SINS algorithms based alignment method is studied.Azimuth angle is parted to satisfy the small angle error assumption.A strapdown inertial navigation algorithm and an associated Kalman filtering algorithm is operated over each angle part.The initial azimuth value of SINS algorithm is set with the middle value of the part.The final optimal navigation solution selection methods in given under two conditions: forward filter correct and feedback filer correct.The alignment algorithm is validated by the simulation and turntable test.关键词
