摘要
介绍了星敏感器的基本工作原理,分析了恒星能量在星图的分布特点,结合星图的特点提出了星敏感器导航星点识别定位方法,按照处理顺序,介绍了导航星阈值确定,连通性分析和内插细分等其中各步骤算法,并用星敏感器通过导航星角距标定新方法对该方法进行了定位精度检测,取得了较为满意的结果。
The basic principle of star sensor is introduced.The characteristic of the star image is analyzed.The methods of the guide star identification for the star sensor are researched with the characteristic of star image.The method of threshold,connectivity analysis and centroid for the star locating is analyzed on the ways of theory and practice.The precision of the algorithm is detected by the guide star＇s principal distance.The experiment proves that the star sensor would get more preci-sion through the new method of calibration.
