摘　　要：本文综述了星敏感器技术的研究现状和未来发展趋势。首先,总结了国内外星载星敏感器的发展历程。接着,根据星敏感器工作原理,分析讨论了星点质心定位算法、星图识别算法和姿态解算算法等星敏感器关键技术的发展现状。通过讨论星点质心定位精度对星敏感器测量精度影响,分析了星点质心定位算法以及对应误差补偿的研究现状;基于星座特征、字符模式和智能行为,介绍了星图识别算法并进行了对比分析;根据确定姿态解算算法和动态姿态解算算法分析了姿态解算算法的研究现状。最后,对星敏感器的未来发展进行了展望,讨论了航空机载星敏感器、微小型星敏感器和甚高精度星敏感器的发展趋势以及未来重点研究内容。In this paper, the research status and development tendency of star tracker technique are reviewed. Firstly, the development process of star tracker at home and abroad is summarized. Then, key techniques such as star centroid algorithm, star recognition algorithm and attitude determination algorithm are summarized re- spectively based on the working principle of star tracker. Based on the influence of star eentroid localization precision on measurement precision of star tracker, the research status of star centroid localization algorithm and the corresponding error compensation are discussed. According to the constellation characteristics, charac- ter models and intelligent behavior, the star map recognition algorithm is introduced and the comparative anal- ysis is developed. According to the determined attitude determination algorithm and dynamic attitude determi- nation algorithm, the research status of attitude determination algorithm is discussed. Finally, the tuture devel-opment of star traeker is prospected, and the dewvelopment trend and key research contents in the future of air- borne star tracker, micro star traeker and super high precision star tracker are discussed.
