摘　　要：针对地球同步轨道(GEO)航天器的在轨服务航天器自主绕飞问题,为了实现对目标的有效观测,本文研究提出了一种考虑光照约束的轨道机动策略。首先,在HILL坐标系中建立了服务航天器与目标航天器之间的相对运动模型,定义了光照方位角来描述太阳光照对目标航天器观测效果。然后,结合航天器相对运动特性,分析了自主绕飞的形成过程,设计了一种考虑光照约束的服务航天器实现自主绕飞的双脉冲轨道机动策略。最后通过数值仿真实验验证了算法的有效性。In order to realize the effective observation of the target spacecraft in the geosynchronous orbit(GEO),this paper proposes an orbit maneuver strategy with the light constraints taken into account.Firstly,the relative motion model between the service spacecraft and the target spacecraft is established in the HILL coordinate system,and the illumination azimuth is defined to describe the observation effect of sunlight on the target spacecraft.Then,combined with the relative motion characteristics of the spacecraft,the formation process of autonomous orbit is analyzed,and a dual pulse orbit maneuver strategy is designed to realize autonomous orbit of the service spacecraft considering the light constraints.Finally,the effectiveness of the algorithm is verified by numerical simulation experiments.
