摘要

An efficient method is developed for filtering the attitude data in the control of fast-maneuvering spacecraft. This paper explains a convenient attitude representation based on a detailed description of the spacecraft's small attitude variations around the free motion with zero angular acceleration. Once the altitude motion equations are linearized, the only residual nonlinearities left are those due to the gyrodynamic torques. Three quasi-linear decoupled filters can then be defined using a particular set of attitude variables to achieve the whole estimation of the spacecraft attitude motion around the three body-referenced axes. The basic mathematical formulation is first exposed. Then, having designed three similar structures to serve as dynamic attitude models, the performance of the method is illustrated in the case of high rate angular motions by comparing data generated by simulation with linear Kalman filters.
