一种集成化的卫星PCM测控与时间同步性能测试系统设计

Design of an Integrated Test System for Satellite PCM TM/TC and Time Synchronization

卫星平台电子系统中遥控、遥测与时间同步性能的优劣关系到卫星安全与实用效能。针对以往平台电子系统对接采用单机自检设备,存在设备零乱、软件系统性较弱的缺点,设计开发了一套集成化的应用于卫星系统级测试的PCM测控与时间同步性能测试系统。系统具备适应不同PCM测控码率与格式要求的能力,可无缝集成功能丰富的综合测试软件,完成测控数据处理,并基于触发时间锁存原理,实现了高精度的卫星时间同步性能测试。

Remote control telemetry and time synchronization are the basic function of satellite platform electronic system,whose performance is related to the safety and utility of satellite. In the past,the joint debugging of the platform electronic system used disordered and inconvenient single test equipments,so an integrated test system for PCM TM/TC and time synchronization performance verification is designed. The PCM test equipment can be adapted to the TM/TC requirement of different bit rate and format,and seamlessly integrate comprehensive test software of various functions to perform data processing.Based in the principle of trigger time latch,the high-precision validation method and test equipment for time synchronization are designed.
