导航星库包括导航星表和星对信息表。
The guide star database consists of guide star catalogue and star pair information catalogue.
仪器星等对正确评估星敏感器的灵敏度、捕获概率以及建立导航星表都有重要的意义。
Stellar instrument magnitudes are important for star trackers; however, there are not simple and accurate methods to estimate stellar instrument magnitudes.
为此，设计了以导航星凸多边形和观测凸多边形之间距离最小为准则的识别算法。针对星光制导的导弹观星时间很短，提出了根据弹道生成弹上导航星表的方法，其导航星表只需存储30颗星的75 个凸多边形。
As the star sensor of ballistic missile works only for short time, the navigation stars in the missile can be reduced to 30, and the convex polygons can be reduced to 75 for different trajectories.
然后，介绍星敏感器相关的导航星星表的建立、星图识别技术。
Secondly, the establishment of the guide star catalog and its star identification technology are introduced.
按一定规则对全天星表的星信息进行了筛选并组建了导航星星库。
The guide star catalog is built with the star information selected from all-sky star catalog on some guidelines.
