Abstract: Based on the developmem of thermal test software at home and abmad, mis paper presents an integrated software platfom of spacecrar vacuum themal envimnment adaptability test, analysis and evaluation, with its basic composition and the functions of each module. This software platform is based on existing domestic thermal measurement and control software and includes the necessary functional modules, integrating the latest research achievements on the themal test deViation, the vacuum themal enVimnmental effects, the test pollution effects and so on, and can realize the integrated platfbm deVelopment of spacecraft vacuum thermal environmental analysis, design, implementation and evaluation.
