| Abstract: | In this paper,we have dericed the rotation vector differential equation and the formula of the relation between the rotation vector and the angular velocity. Besides,we have also derived a recursive algorithm expression from the rotaion vector differential equation,the noncommutativity error is divided into two parts in this expression,one of them can be compensated directly and accurately,while the other can merely be estimated according to the gyro outputs,this important conclusion is the base of deriving the algorithms to restrain the noncommutativity error. |
