摘　　要：针对天文/惯性组合导航中对星敏感器快速姿态测量的要求,提出了一种基于星体跟踪的星图识别算法应用于星敏感器姿态测量。建立了基于星区的导航星库便于快速搜索导航星。实验结果表明,该算法比传统星图识别算法有着明显的优点,识别速度快,识别成功率高。To satisfy high speed attitude measurement specifications of star sensor in CNS/INS integration navigation, a new algorithm of star recognition based on stars tracking is presented used in star sensor attitude determination. The guide star catalog based on star zone is built for quickly searching guide stars. The experiment results show that the proposed method has an obvious advantage compared with the traditional star recognition algorithm, such as higher speed of recognition, high er recognition success rate.
