Attitude calculation is the core part of inertial navigation. When the output of the inertial group is the angular rate, this paper refers to the idea of the monadic attitude algorithm. In the angular velocity polynomial fitting process, the angular velocity polynomial information of the previous period is used to integrate the angular velocity polynomials in multiple different fitting intervals. The angle increment information corresponding to the sampling period is extracted, and then the angle rate information and the angle increment information after multiple corrections are used to construct a cone error compensation structure. The simulation results show that the new algorithm can not only increase the attitude update frequency of the traditional angular rate attitude algorithm, but within a certain cone frequency range, the calculation accuracy of the traditional algorithm is improved by 2 to 3 orders of magnitude.
