本文首先讨论建立星敏感器用导航星星表的方法和过程,在此基础上统计出导航星的视场密度和导航星星图模式的唯一性并分析了它们与星图识别成功率之间的关系,由此对星敏感器的视场尺寸和灵敏度提出了要求。
In this paper, we first discuss the method and process of establishing a star catalog with satellite sensor, and then calculate the uniqueness of the navigation field density and navigation star schema and analyze the relationship between them and the success rate of star chart identification. Thus the requirements of the field of view of the star sensor size and sensitivity requirements.
