摘要: 基于双轴伺服的天文姿态测量设备一般采用双参考矢量法进行测姿,更新率高,简单可靠,但由于受大气扰动和蒙气差等因素影响,测姿精度不高。根据动态条件下的舰船姿态测量需求,提出了一种主动寻星式的天文姿态测量方法,重点分析了寻星策略生成,简要介绍了巡天观测和姿态解算过程,并对该方法实际应用效果进行了试验验证,为研制新型舰船天文姿态测量系统提供了重要参考。

Abstract: The attitude measurement equipment based on biaxial servo usually adopts the double reference vector method to measure the attitude, which has high updating rate, simple and reliable. However, the accuracy of attitude measurement is not high due to the influence of atmospheric disturbance and air cover difference. An active star search method for astronomical attitude measurement is proposed, the generation of star search strategy is analyzed, the survey observation and attitude calculation process are briefly introduced, and the practical application effect of this method is verified by experiments, which provides an important reference for the development of a new type of astronomical attitude measurement system for ships.
