摘　　要：研究通过近圆太阳同步轨道卫星倾角修正控制使卫星降交点地方时反向漂移的方法,给出了控制动力学方程,分析了倾角控制的电源、轨控推力器和地面测控系统等约束条件并提出了轨道控制方案。介绍了我国首次太阳同步轨道卫星大倾角修正控制的在轨实践,对轨道倾角控制精度进行了分析和评估。修正过程中利用陀螺常值漂移对姿态机动的影响,使倾角控制对半长轴产生有利的耦合作用,减少了推进剂消耗。在轨实测结果验证了该法对降交点地方时漂移控制的有效性。The active control method of local time of descending node drift toward opposite direction of a SSO remote satellite was studied in this paper.The dynamics formula was given out.The constraint of power,thruster and ground test system in inclination control was analyzed and the control scheme was put forward.The on-orbital practice of orbit inclination modify which was the first implementation in domestic was introduced.The orbit inclination control precision was evaluated.The effect of the gyro＇s systematic drift on the attitude was used to cause the couple,which would reduce the consumed fuel.The measurement of orbit elements proved that the method proposed was in effect to drift control for local time of descending node.
