摘　　要：为了将航天器上广泛采用的星敏感器技术实际应用于舰船,对传统星敏感器面向舰船使用的制约因素进行了细致的研究实验。在此基础上,针对传统星敏感器视场小、信息获取量少、偏航角误差大等缺陷,在星敏感器的整体设计上,提出了成固定夹角的双通道观测方案,通过像空间坐标系转换的方法,实现了星敏感器视场的拼接。在保证星敏感器小视场观测精度的基础上,获得更多的星体信息,达到了造价昂贵的大视场星敏感器的观测效果,有效提高了星敏感器的三轴姿态测量精度。The constraints of the traditional star sensor which has been used widely in spacecrafts applications are studied in detail. With the aim of solving the problem of traditional star sensors, such as small field of view, limited information output, course error, a fixed-angle dual-channel observation scheme is put forward. Through space coordinate system conversion, the view fields of two star sensors are integrated. The design of dual-channel star sensor observation acquires stars in a wide range while retaining the precision of the star sensor with narrow field of view.
