With the increasing use of Micro-satellite large-scale networking applications, traditional single-satellite measurement and TT C ground test systems have been unable to satisfy the requirements for batch and concurrent testing. This paper proposes a design method for a universal measurement and TT C ground test platform that is suitable for multi-satellite concurrent testing. It also designs and presents a system solution and implementation process for three typical satellites concurrent test. The platform is designed to add configuration items of multi-satellite concurrent test to the original ground test platform. Testers only need to select the appropriate satellite for testing. The platform is more functional and more versatile. It has been successfully applied to the concurrent testing of a satellite constellation, which has greatly saved manpower and shortened the constellation satellite test time, and has received good results.
