Abstract: The design method of the satellite vacuum thermal test database is discussed in this paper. The vacuum thermal test database is an essential subsystem of the satellite environment engineering database system, and the implementation of the online data format transformation, the batch input and the real time response are presented. The requirement analysis, the overall architecture and various functionality modules, and comprehensive analysis are given. The satellite vacuum thermal test database has been used in the management of thermal test data, with the remote online data access and a fundamental data platform is provided for the satellite virtual test research.
