The task volume of TT&C equipment executing satellite management tasks is increasing day by day. The daily shutdown maintenance, performance index testing and increasing workload of equipment have become contradictory. Equipment maintenance and performance index testing demand efficient automated testing methods. This article researches the integrated operation management system based on lightweight cloud, analyzes the software and hardware composition of the automated testing system, deploys automated testing software on the integrated operation management system, and improves the reliability of software operation. It has also proposed an automated testing strategy for high-density task states, optimized the automated testing process, and implemented the function of rapid and automated testing of TT&C performance indices. By testing the effective isotropic radiated power—EIRP value of the system, and applying the automated testing system in practice, the testing efficiency has been significantly improved.
