In this paper,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.
