The Additional Guide Star (with star flag 5) is come into use for improving the accuracy and speed of star identification. After the cases analysis of unsuccessful star identification, giving the guide star which always cause false star identification a given star flag(such as 6), which denote that the star is a Redundant Guide Star and can't take part in the star identification processing. Through the introduction of Redundant Guide Star, the accuracy of star identification is improving. The distribution of Additional Guide Stars spread all over the whole sky, even the star sparse area.
在选取导航星的过程中，位置精度阈值的引入，使得高精度的恒星作为导航星，为高精度的卫星姿态反演奠定了基础；辅助导航星的引入，与单一使用Tycho-2星表相比引入了大量的亮星(189颗辅助导航星遍及全天球，其中亮于3等星的恒星占34.4%)，且弥补了部分天区恒星稀疏无法满足星图识别条件的不足，这将十分有利于提高星图识别速度和识别率；冗余导航星的剔除，为进一步提高星图识别率提供了可能。

Plates of globular cluster M3, taken with the 40cm refractor at Sheshan station of Shanghai Astronomical Observatory, are used by this work. The difference of epoch of these plates is up to 81years. The positions and absolute proper motions of 24 stars in ACT catalogue, which links with the Hipparcos Catalogue based on the International Celestial Reference System, are used as the reference frame. Using the central overlapping principle, the absolute proper motions of 534 stars in the region of about 100'×100' around the cluster are determined. After the membership determination of the stars which based on the data of proper motions, average absolute proper motion components for the cluster of -0.3±0.3 mas/yr in R.A.

astrometry：天文测量学
什么是天体测量 天体测量学或天文测量学(Astrometry)是天文学中最古老也是最基础的一个分支,主要以测量恒星的位置和其他会运动天体的距离和动态. 他是传统科学中的一个子科目,后来发展出以定性研究为主体的位置天文学. 天体测量学的历史,

Betelgeuse：参宿四
说明: 参宿四(Betelgeuse)确实是个巨大恒星,如果把它放在太阳的位置上,那个它的云气结构会延伸到木星轨道. 除了太阳以外的恒星,像是参宿四都距离的太遥远而使他们看起来只有一个星点,即使是透过非常大的望远镜来观察也是. 然而,

Tycho Brahe：第谷.布拉赫
当时天文学家第谷-布拉赫(Tycho Brahe)发现这颗超新星距离地球很远. 这项研究颠覆了2000多年以前古希腊科学家亚里士多德的理论,亚里士多德认为地球位于同心球体中心,该球体中的恒星位置都是固定不变的.
-
hour angle：时角
当天文学家要寻找一颗位置已知的星的时候,他只要先望一望恒星时钟,从恒星时中减去该星的赤经,便得到它的当时的"时角"(hour angle),或者说在子午圈偏东或偏西的距离.

proper motion：自行
事实上,恒星在正常情况下,它们的颜色与亮度在很长的时间尺度内不会有变化(只有变星以及新星和超新星爆发时才例外);恒星在天空中的相对位置,虽然存在着规律性的缓慢移动--即恒星的"自行"(proper motion)但古代中国人并未发现这一移动;

Telescopium：望远镜座
现代通用的星座有 88 个,其中有些是近代才加添的 (例如望远镜座 (Telescopium)). 同一星座内的恒星通常没有实际的连系,恒星之间的距离可以非常遥远. 对地面观测者来说,当天球自转时,星座也随之起落. 地面观测者所处之位置限制了他可以看见的星座.
