摘　　要：航天器在某些姿态敏感器故障的情况下 ,经多种组合进行自主故障判断、故障定位及重组后融合定姿 ,仍能保证姿测精度 ,或者在稍降低定姿精度的情况下 ,使航天器降级工作 。In this paper, a information fusion concept using redundant measurements obtained by high accuracy attitude sensors on spaceraft is presented, ensuring attitude determination accuracy for spacecraft by means of informant fusion of redundant measurements obtained by different attitude sensors after autonomous failure diagnosis, location and reconfiguration in failures of some attitude sensors, or fail-operation for spacecraft in graceful degradation.

关 键 词：自主故障判断 信息融合 航天器 姿态敏感器 冗余测量
