Abstract

Complex interference of angular swaying and linear motion can depress the alignment performance of the rotary strapdown inertial navigation system（ SINS）. In order to solve the problems

a rapid alignment algorithm for rotary SINS in inertial frame is presented. Based on error characteristics of rotary SINS

design a coarse alignment method in inertial frame. And an improved rotary SINS gyrocompass alignment algorithm is proposed to speed up the alignment and increase precision. Simulation results show that the proposed algorithm can accomplish Rotatry SINS alignment quickly

and make azimuth accuracy confine to 1. 35 minute of arc in 7 min.
