摘　　要：鹊桥二号作为地月通信中继卫星,其意义在于能够在地球和月球之间建立稳定的信息交换通路,使得月球背面探测器与地面站之间能够进行信息交换,获取珍贵的探测数据和样本.提出了鹊桥二号星务分系统多路径信息处理技术,设计了高速遥控通道与低速遥控通道信息流传输方案,高速遥控通道支持大规模软件上注更新,也可作为低速遥控通道的备份,实现了遥控多路径.此外,提出了一般遥测、详细遥测及应急遥测等遥测多路径和多模式设计,增强了卫星的可靠性、灵活性和适应性.该技术实现了对嫦娥六号月背采样返回任务及嫦娥四号中继通信的支持,在为期一个多月的嫦娥六号任务中,执行并转发了超过2000条指令,有效保障了任务顺利完成,并具备对未来嫦娥七号和嫦娥八号任务提供通信保障的能力.As an Earth-Moon communication relay satellite,Queqiao-2 Satellite is designed to establish a stable information exchange path between Earth and Moon,enabling the connection between the lunar exploration spacecraft on the far side of the Moon and the Earth′s ground station,as well as the acquisition of valuable detection data and samples.The multi-path information processing technology for the housekeeping subsystem of Queqiao-2 Satellite was proposed,and an information transmission plan was designed in terms of high-rate and low-rate telecontrol paths.The high-rate telecontrol path could support large-scale software upload and update,as well as work as a backup for the low-rate telecontrol path,thus achieving the multi-path design of telecontrol.Furthermore,the multi-path and multi-mode design of telemetry was described in detail,including normal telemetry,detail telemetry and emergency telemetry,which could effectively enhance the reliability,flexibility and adaptability of the satellite.The current technology had already realized the support for the sample return from the far side of the Moon of Chang′e-6 mission and the communication services of Chang′e-4 mission.During the one-month mission of Chang′e-6,the satellite carries out and transmits more than 2000 instructions,effectively supporting for the mission objective.The system is also capable to support Chang′e-7 and Chang′e-8 missions and provide relay communication services in the future.
