| 摘 要： | 在选用高精度基本星表的基础上,分析了导航星的选取方法及其分布特征。为了利用导航星的观测位置信息,给出了从星表平位置到星心视位置的高精度转换方法。基于分区法制定了导航星库,并给出了存储及读取方法,对该星库的访问具有简单、快速、占用资源少等优点,适合星载使用。

| Abstract: | In order to meet the requirement of high precision measuring device,guide stars are selected from high precision fundamental star catalogue.The distribution of guide stars is analyzed.To use the star's position information,the method of transformation from mean position in fundamental star catalogue to sight position based upon satellite is given.The guide star catalogue is established according to sphere zoning method.And the approach to save and read stars in guide star catalogue is discussed.Accessing to the guide star catalogue is easy,fast and efficient.It is suitable for satellite,spacecraft,missile and so on. |
