摘要
Abstract
In determining the attitudes of spacecraft, the filter diverges due to model error. According to the method of covariance matching, an adaptive attitude determination algorithm based on A-matrix residual is proposed. It is the best online attitude quaternion least-square fitting recursive algorithm by adjusting the covariance of the noise. By studying ^-matrix and the statistical properties of the structure, adaptive residual and standard are designed to solve the disadvantage of traditional residual definition. Due to the high-valued residual made by measure noise or courage noise or both, the adaptive filtering to measure noise and courage noise are studied respectively. The simulation shows that this algorithm can compensate measurement noise deviation.关键词
