摘要
介绍了星敏感器的基本组成及工作过程。对恒星检测所涉及的一些问题,如视场内可探测恒星平均数、星图处理、恒星像点位置确定等问题进行了研究和实际验证。
A star sensor is an electro-optical instrument used to provide the absolute 3-axis attitude with respect to the celestial sphere of a craft utilizing star observations. Star trackers are the most accurate means of absolute attitude determination with accuracies down to arc seconds. The basic composition and operation procedure of the star sensor are introduced in this paper. Some problems in star observations by using star sensors are studied as well. They are well verified by the experiments.
