The invention discloses a satellite attitude determination method and device based on multiple star sensors, aiming at satellites provided with two or more star sensors, the satellite attitude is determined by fully utilizing the measurement information of each star sensor, and meanwhile, the satellite attitude is determined by utilizing the measurement information of each star sensor. According to the method, the attitude state of the target satellite at the next moment is predicted by using the satellite attitude information determined at the previous moment, and the attitude state is used as the initial value of the attitude filtering calculation of the target satellite at the next moment, so that the attitude determination method provided by the invention is small in calculation amount and high in accuracy. And the star sensor can be fully utilized to measure information, so that the on-satellite attitude determination precision can be effectively improved, and the method is suitable for being widely applied and popularized in the field of satellite attitude determination.
本发明公开了一种基于多星敏感器的卫星姿态确定方法及装置,本发明针对安装两台及以上星敏感器的卫星,充分利用各个星敏感器的测量信息进行卫星姿态确定,同时,本发明使用前一时刻所确定出的卫星姿态信息来进行目标卫星在下一时刻姿态状态的预测,并将其作为目标卫星下一时刻姿态滤波计算的初始值,基于此,本发明所提供的姿态确定方法,不仅计算量小,而且能够充分利用星敏感器测量信息,由此,可有效提高星上姿态确定精度,从而适应于在卫星姿态确定领域的广泛应用与推广。
