The Direct Quaternion Method in Initial Alignment of SINS

Shi-Jiao AN, Chun-Xi ZHANG

Abstract


In this paper, the initial quasi-quaternion method of strapdown inertial navigation system (SINS) is proposed, in order to solve the singularity problem of the initial alignment algorithm. And mathematical simulations is conducted and analysed Simulation results show that the method is feasible.
