Combining with engineering application, the quaternion and rotation vector attitude algorithms which are mainstream algorithms are introduced, and a new method of finding a solution to quaternion and three subsample rotation vector in typical coning movement is proposed and analyzed through the simulation. The results show that quaternion has smaller amount of computations in the mode of gyro velocity input, but its precision is not better than rotation vector attitude algorithms. Meanwhile, rotation vector attitude algorithms meet requirements of high-dynamic and high-precision, but its noise amplification is more obvious.
