Abstract: For meeting the general utility of satellite control system testing, a test framework is proposed based on ATS（automated test system） concept and ATML（automatic test markup language） standard. The universal testing platform is composed of three parts: general test station, test adapter, integration development and running environment. The test requirements and test capability are decoupled through the system description scheme using ATML standard and signaloriented method. The general utility is realized via configuring the universal testing platform according to the test capability and requirements.

Key words: satellite control system, ATML standard, universal testing platform
