  • Abstract
    In this paper, a new approach based on the q-method for coarse alignment is presented. Compared with the standard approach which is based on determining DCM (direct cosine matrix), the new method can avoid solving the DCM and get the initial quaternion directly that we used for the navigation calculation.
