摘　　要：介绍了嫦娥四号任务月球背面中继链路飞控工作模式设计方案。针对月球背面探测需要克服地面测控网与月球背面探测器之间存在地基测控盲区的需求,嫦娥四号任务在工程设计上采用在月球背面地月连线上的L2点布设中继星的方式,在世界上首次采用地月L2点中继星实现对地对月中继通信。从嫦娥四号月球背面探测任务飞控需求出发,分析将中继星引入深空探测任务天地测控大回路对飞控实施的主要影响,设计了基于月球中继星的深空探测任务飞控模式,嫦娥四号任务飞控工作取得圆满成功,验证了该模式的正确性和有效性。In this paper,we concentrate on the flight control mode design for the Chang'e-4 lunar relay communication link.Aimed at overcoming the blind zone of measurement and control between ground stations and the probe located at the far side of the moon,a lunar relay communication satellite is adopted for the first time in the world in the Chang'e-4 mission,which revolves around the Earth-Moon L2 point to realize the ground communication of the lander and rover.The flight control requirement for the lunar exploration of the far side of the moon is elaborated is this paper.The major influence of the introduction of lunar relay satellite into the loop of the measurement and control between the probe and the ground is analyzed.Moreover,the flight control mode based on the lunar relay satellite for deep space exploration mission is designed,the correctness and availability of which is validated in the flight control practice of the Chang'e-4 mission.
