| Abstract: | Attitude matrix is represented by quaternion and rotation vector in strapdown inertial navigation system.The quaternion algorithm and the improved rotation vector algorithm are discussed under the condition of conical motion.Simulation results show that when the sample frequency is higher,the accuracy of the rotation vector algorithm is better than that of quaternion algorithm. |
