The invention provides an attitude trajectory planning method for satellite non-trace curve imaging, and relates to the technical field of satellite attitudes. The attitude trajectory planning method for satellite non-trace curve imaging comprises the following steps: S1, according to the position of a ground imaging point curve A and the orbit of satellite operation, respectively determining the imaging moment T of a satellite to a ground imaging point, and recording a sub-satellite point position K of the satellite at the imaging moment. According to the attitude trajectory planning method for satellite non-trace curve imaging, by determining the imaging moment T of the satellite to the ground imaging point according to the position of the ground imaging point curve and the orbit of the satellite operation, the ground imaging point can be conveniently selected, and the coverage area and the tracking quality of the curve trajectory are improved. According to the attitude trajectory planning method for satellite non-along-track curve imaging, the high-precision attitude angle and the angular velocity of the attitude angle can be effectively obtained by constraining the curve attitude orientation of the imaging point, so that the effect of improving the attitude trajectory precision of non-trace curve imaging is achieved.

    本发明提供一种卫星非沿迹曲线成像的姿态轨迹规划方法,涉及卫星姿态技术领域。一种卫星非沿迹曲线成像的姿态轨迹规划方法,该方法由以下步骤组成:S1、根据地面成像点曲线A的位置以及卫星运行的轨道,分别确定卫星对地面成像点的成像时刻T,同时记录成像时刻卫星的星下点位置K。该卫星非沿迹曲线成像的姿态轨迹规划方法,通过地面成像点曲线的位置以及卫星运行的轨道和确定卫星对地面成像点的成像时,能够方便的选取地面成像点,提高曲线轨迹的覆盖面积和跟踪质量。该卫星非沿迹曲线成像的姿态轨迹规划方法,通过对成像点曲线姿态指向的约束,可以有效的得到高精度的姿态角及其角速度,从而实现了提高非沿迹曲线成像姿态轨迹精度的效果。
