摘　　要：根据嫦娥四号探测器开展月球背面探测的中继通信需求,基于地月系平动点特性,建立考虑三体引力的高精度动力学模型,给出不同飞行阶段的轨道求解方法。在动力学模型和求解方法基础上,结合嫦娥四号"鹊桥"中继卫星的轨道设计,提出了最佳轨道方案和轨道控制策略。"鹊桥"卫星的飞行实践结果表明:动力学建模及轨道设计结果正确,满足中继任务需求,相关模型和方法可为未来平动点任务提供参考。According to the relay communications requirement of Chang’e 4 for the exploration on the far side of the moon and the characteristics of earth-moon system libration point,high fidelity dynamic models considering three-body gravity and orbit solution method in different flight phase are introduced.Then,combined with the orbit design of Queqiao relay satellite of Chang’e 4,orbit design scheme and control strategies are proposed based on dynamic model and solution method.The flight results of Queqiao satellite demonstrate the correctness of dynamic modeling and orbit design which fulfill the relay mission requirement.The model and method proposed can provide references for the future libration point missions.
