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 plat-form 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 con-nection relationship to facilitate parallel test of multiple satellite channels and dual redundancy of ground test equip-ment. 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 al-ready been used in ground tests of a satellite with satisfactory results.
