The invention provides a drift angle real-time compensation method for tracking an imaging satellite of a ground dynamic target, and the method comprises the steps: carrying out the tracking of a drift angle through the geographic position information of the ground target and the conversion relation among an inertial system, an earth-fixed system and a satellite-to-earth coordinate system; and solving a three-axis attitude calculation method for compensating the drift angle in real time when the satellite performs tracking imaging on the ground moving target. The method can improve the definition of earth observation and target tracking imaging of the satellite camera, and has practical significance for the ground dynamic target tracking imaging task of the satellite.
本发明提供一种对地面动态目标进行跟踪成像卫星的偏流角实时补偿方法,通过地面目标的地理位置信息以及惯性系、地固系和卫星对地坐标系之间的转换关系,求解出卫星在对地面动目标进行跟踪成像时实时补偿偏流角的三轴姿态计算方法。本发明能够提高卫星相机对地观测与目标跟踪成像的清晰度,对卫星的地面动态目标跟踪成像任务具有现实意义。
