| 摘 要： | 导航星表是星敏感器系统用来实现恒星星图识别和姿态确定的唯一依据，它的容量、内容、存储读取方式对于完成星敏感器功能和性能指标都极为重要．通过分析恒星在视场中的分布规律，建立起星表的完备性和冗余性与星敏感器视场内导航星的数量之间的关系，确定了导航星数量，提出了筛选导航星的原则和方法，为了实现星表的快速搜索，对导航星表的组织形式进行了详细讨论．构造一个由2510颗0～6等导航星组成的导航星表，满足了星敏感器星图识别和姿态确定的需求．

| Abstract: | A navigation star catalog is used to identify stars and determine satellite altitudes and the capacity, content, storage mode of the navigation star catalog are vital to the function and performance of a star tracker. Through analyzing distribution of stars on the celestial sphere, the relationship between the completeness and redundancy and the number of stars appearing in the field of view of the star sensor is established. The number of navigation stars is determined, and then principles and methods choosing navigation stars from a set of candidates are given. The storage mode of navigation stars is discussed to realize quick search. Based on 2510 navigation stars with 0 -6 magnitude, a navigation star catalog satisfying requirements of the star pattern recognition and attitude determination is constructed. |
