摘　　要：针对载人航天任务中面临的与空间站保持长期共轨飞行的轨道问题,分析了航天器在地球扁率J_2项摄动以及大气阻力摄动作用下,长期共轨飞行航天器半长轴、相位和升交点赤经的变化特性,并设计了仅通过面内调整同时实现面内和面外调整的共轨维持的控制策略。通过仿真算例验证了控制策略的有效性,轨道维持的燃料消耗合理。可为我国载人航天器与空间站共轨方案设计提供参考。Aiming at the orbital maintenance problem of keeping company with space station orbit for a long duration, the characteristics of semi-axis, phase and ascending node right ascension under the influence of J 2 perturbation and atmospheric drag are analyzed,and an orbital maintenance strategy of through plane maneuvering to realize plane and out-of-plane maintenance are proposed and simulated. Simulation results show that the orbital maintenance strategy and fuel consumption is reasonable. This paper can provide a reference for co-orbital manned-spacecraft and space station.
