Abstract�� Basing on rotation vector method, Euler angles method and finite rotations method, the coning motion and its influence were discussed. Then the expressions of equivalent gyro drift in each method and their relationship were obtained. At last compensate precision of two-intervals coning compensate algorithm was researched in each method. The results show that finite rotations method and rotation vector method are equivalent absolutely. Euler angles method and rotation vector method are equivalent only when oscillation angles are small. Coning compensate algorithms are effectual both in rotation vector method and Euler angles method, and besides, compensate precisions are equivalent when oscillation angles are small. Rotation vector method and finite rotations method can be used to design coning compensation algorithms and Euler angles method can be used to design the test of the coning motion.
Keywords�� coning motion   equivalent gyro drift   rotation vector   Euler angles   finite rotations
