摘　　要：与近地轨道交会对接相比,无人月球轨道交会对接由于其月球空间环境和测控资源的限制,对系统的自主性、快速性和鲁棒性都有较高要求。文章从信息流设计角度出发,提出了一种以空空通信链路为基础,构建地面站、目标航天器、追踪航天器的双目标中继通信链路平台,设计了一种支持上下行通路双向自由传输的空空通信方案,通过目标航天器、追踪航天器中的任一航天器,均能实现两航天器上下行数据的自由传输,以提高月球轨道交会对接期间航天器与地面站上下行测控链路的灵活性和鲁棒性。Compared with low earth orbital rendezvous and docking(R&D), unmanned lunar orbital R&D system has higher requirements for autonomous control, quick response and robustness, due to the deep space environment and link resource constraints. Based on the space to space communication links a bi-objective relay communication platform with information flow design is proposed for the signal transmission among the ground station, target spacecraft and chasing spacecraft. A space to space communication system is designed to support uplink and downlink free transmissions. In this system, any target spacecraft or chasing spacecraft can ground station and another spacecraft to support with uplink and downlink data transmission, improving the flexibility and robustness of telemetry and telecommand links communication in R&D.
