| 摘 要： | 作为"嫦娥4号"任务的重要组成部分,中继星将为着陆器和巡视器提供中继通信支持。不同于其它月球探测器,中继星首次选择了绕地月L2平动点运行的晕(Halo)轨道以保证对月球背面的着陆器和巡视器提供连续的中继通信服务,面临诸多技术挑战。在对中继星任务特点进行分析的基础上,梳理了研制中的技术难题,包括使命轨道的选择、使命轨道的到达和长期维持、中继通信体制选择等,并提出了解决方案。中继星的总体设计方案概述也在文中给出。

| Abstract: | The relay communication satellite is an important part of Chinese Chang''e-4(CE-4)Lunar farside exploration mission. The relay communication satellite will provide relay communication support for the lander and the rover on the lunar farside. Different from other spacecraft for lunar mission,a Halo orbit around the Earth-Moon L2 liberation point is used to provide continuous communication links to the lander and the rover on the farside of the Moon. A series of challenges have to be faced. Based on the analysis of the mission characteristics and mission requirements,the technical difficulties are identified and solutions for these problems are given,including selection of mission orbit,arriving and maintenance of the mission orbit,the relay communication design trade-off,etc. The system design overview of the CE-4 relay communication satellite is also given in this paper. |
