航天器高精度姿态敏感器冗余测量信息智能融合技术

Intelligent Fusion of Redundant Measurements of High Accuracy Attitude Sensors on Spacecraft

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.
