S频段微波统一测控系统双点频跟踪链路的设计

Design of Downlink Converters in a Microwave Unified S-Band TT&C System to Implement Dual-frequency Tracking

月球探测卫星的飞行姿态和轨道特点决定了卫星天线有交替覆盖测控站的现象。为了保证下行遥测信号的连续接收,本文提出了S频段微波统一测控系统(简称USB)双TT&C点频跟踪链路设计的若干方案并进行了分析比较。

Because of the moon - surveying satellite＇s attitude and orbit, its two antennas, with different frequencies, will cover the ground station alternately. To ensure continuous receiving of telemetry signal, this paper presents several schemes of configuring downlink converters in the microwave Unified S - Band （USB） TT＆C ground station, then makes a comparison between these schemes.
