针对半球谐振陀螺与星敏感器松组合系统在寡星条件下无法正常工作的问题,采用新的星图识别算法和新的数据融合观测方程,使星敏感器在观测到的导航星数量为1或2颗的情况下完成星图识别,从而能够完成组合测姿。 Aiming at the problem that the combined system of the hemispherical resonator gyroscope and the star sensor loose can not work properly under the condition of oligarchs, the new star-map recognition algorithm and the new data fusion observation equation are adopted to make the star sensor observe the number of navigation stars as 1 Or two stars in the case of completion of the identification, which can complete the combined attitude measurement.
