Xinlong Wang, Gongxun Shen

Open publisher page 0 citations

Abstract

In this paper, a strapdown inertial navigation system (SINS) error model is introduced, and the observability of the SINS error model is analyzed. Then, on the basis of this SINS error model and the analysis of computer simulation results, a fast and precision initial alignment method of the multiposition is proposed for SINS on stationary base. Consequently, the time of initial alignment is reduced, and the precision of the initial alignment is improved greatly. The computer simulation results illustrate the efficiently.
