摘要
对萤火一号(YH-1)火星探测器测控数传分系统的测控数传一体化设计进行了研究。介绍了分系统的作用与功能、上下行射频通道和各单机设计方案,以及性能指标。给出了甚长基线干涉(VLBI)信标测试试验、中俄测控对接试验、射频测试试验的结果。给出了分系统设计中采用的小型化集成化、高灵敏度接收及高集成度发射技术。设计的测控数传分系统可满足距离4亿千米通信的需求。
Abstract：The TT＆C and data transmission integrated design for the YH-1 Mars probe was studied in this paper. The function, the design channel and device, and performance were introduced. The results of the joint experiment between China and Russia and RF test were given out. TT＆C and data transmission subsystem of schemes of the upstream/downstream RF very long baseline interference beacon test, The technologies adopted in the subsystem design of the miniaturization and integration, high sensitive receiving and high integrated transmission were given out. The subsystem designed could meet the requirement for the communication with the distance 4×10^8 km.
