摘　　要：对萤火一号(YH-1)火星探测器测控数传分系统中的高稳定频率源设计进行了研究。给出了频率源的晶振选取,以及主要电路与可靠性安全性设计。对研制的频率源的稳定度、相位噪声、老化率等常规测试,模拟环境中单机及整器的高低温、力学、热真空等环境试验,以及星地对接试验的结果证明:高稳定频率源满足星地通信及甚长基线干涉(VLBI)测轨的需要。The design of the high stability crystal source in TT~＇.C and data transmit subsystem of YH-1 Mars probe was studied in this paper. The crystal choosing and design of the main circuit and reliability and security were given out. The experiment results of the normal test such as stability, phase noise and aging rate, environment test such as high-low-temperature, mechanics and thermo vacuum of the unit and whole probe, and linking test of the probe and the earth showed that the high stability frequency source designed would meet the requirement of the TM~.TC compatible test and very long baseline interference orbit determination.
