摘　　要：一般地面测试平台无法同时支持卫星对地测控测试和中继测控测试,需要开发多通道地面测试平台满足卫星测试需求。基于此,对卫星测控系统多通道地面测试平台设计进行讨论,采用彼此相对独立的2套地面测试设备,通过特定连接关系同时接入卫星对地测控链路和中继测控链路中,实现卫星多通道测控并行测试和地面测试设备的双机备份,在无须更改外部连接关系的基础上,通过模式选择、参数配置,可适用于不同模式下卫星测控通道地面测试需求。经过分析,该平台具有功能完善、适用性广、稳定性好等优点,已应用于某卫星的地面测试。测试结果表明,平台运行稳定,具有良好的使用效果。As ordinary ground test platforms do not support satellite-to-ground and relay testing at the same time,a multichannel ground test platform was developed for satellite testing.In design of the multichannel ground test platform for satellite TT＆C（Tracking,Telemetry and Command）systems,two sets of relatively independent ground test equipment were used and they were connected to the TT＆C link and relay TT＆C link through a particular connection relationship to facilitate parallel test of multiple satellite channels and dual redundancy of ground test equipment.The platform can adapt to various demands of different modes of satellite TT＆C channel ground tests through mode selection and parameter configuration without changing the external connection relationship.The platform was demonstrated to have features of wide functionality,excellent adaptability and high stability.It has already been used in ground tests of a satellite with satisfactory results.
