摘要
姿态敏感和姿态稳定是卫星的重要技术之一，星体敏感器是目前最高精度的姿态测量技术。对于这种技术，很多文献都进行了讨论，并涌现了许多关于星图匹配行之有效的算法。从这些算法中，提取了几种较好的星体识别算法，又分别比较了它们的优缺点，并在这些算法的基础上，重新提出了另一种新型星图匹配算法（三角形匹配算法），以便提供更可靠、更实时、更独立的星体识别。
Attitude sensitivity and stability are the important technical features of satellite.Measuring satellite attitude with star sensor is a present measuring technique with highest accuracy.Based on this technique the star identification is discussed in many literatures and a lot of effective algorithms for star map matching emerged.Several better star identification algorithms are selected from these algorithms.In order to provide a more reliable,rapid and autonomous star identification for adapting a wide variety of space missions and applications,a novel star map matching algorithm—triangular matching algorithm,was proposed on the basis of these algorithms.
