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。
