An algorithm based on optimal attitude matching for transfer alignment

According to the relationships among attitude error of mathematical platform, installation angle and measurement misalignment, the measurement misalignment matching algorithm is derived. In order to ensure the system works well on the condition that the mount angles of the slave INS are big, the optimal attitude matching algorithm is presented detailedly based on the measurement misalignment matching algorithm. Finally, the simulation results show that the proposed transfer alignment algorithms are effective and reliable enough to improve the precision of transfer alignment.
