Although main INS with high accuracy, its' error affects transfer alignment precision of slave INS.

虽然主惯导的精度相对较高，但其误差仍对传递对准精度产生影响。

The above three attitude matching algorithms are derived on the condition that the mount angles of the slave INS are small.

基于此，对“量测失准角匹配法”进行了完善，推导出了一种可在多挂点下使用的现代姿态匹配算法——最优姿态匹配法。
