Abstract

Initial alignment is one of the important factors to affect the accuracy of strapdown inertial navigation (SINS). SINS observability analysis indicates that fixed position SINS is not completely observable, and the multiple position alignment method can make SINS completely observable by changing the IMU location. In addition, the multiple position alignment method can improve the precision of initial alignment. In this chapter, the four-position alignment method was analyzed, and SINS four-position alignment system was realized based on FPGA and DSP. The experiment of a certain vehicle indicated that this proposed four-position alignment system is feasible.
