摘　　要：基于深空测控通信特点及其技术难点,对萤火一号(YH-1)火星探测器测控通信分系统设计进行了研究。给出了测控通信方案和分系统构成,介绍了火星-地球超远距离通信,小型化测控通信系统,高灵敏度接收机,高集成度发射机,小型化高稳定频率信标,集成化、小型化遥控指令译码器等关键技术设计及主要技术指标。YH-1火星探测器的测控和数传分系统采用一体化设计方案,在质量10kg约束条件下,实现了上行遥控通道及下行遥测通道,具备科学数据传输通道及测定轨信号发送的功能,且每个通道均有冗余备份设备。Based on the characteristic of the deep space TT＆C, the design of the TT＆C subsystem for YH 1 Mars probe was studied in this paper. The TT＆C technology scheme and the composition of the subsystem were given out. The key technology of ultra long distance communication between Mars and the earth, miniaturization TT＆C system, high sensibility receiver, high integrated transmitter, miniaturization high stable frequency beacon, integrated miniaturization telecommand decoder and their major performance were presented. The integrated design was adopted in the TT^-C and data transmission subsystem for YH-1 Mars probe. The up-link channel and down- link channel were realized under the constrained condition with mass 10 kg, which had the science data transmission channel and the function of the data transmission of the orbit measurement and determination. Each channel had its redundancy device.
