Abstract:  In the process of space payload development, the test equipment on-ground is indispensable because the payload must has been tested through and calibrated before its launch. To assure manipulation security of payload on-ground, this paper focuses on the security design of the test equipment on-ground to protect the payload against any damage and to keep it in good condition. We implement the test equipment access control through a kind of IC card-reader to restrict all of operators’ manipulation. Then every manipulation to the payload through equipment will be registered to be the manipulation log. The test equipment will check every manipulation validity before it is executed so that the mishandling can be shielded to avoid any damage to the payload. The security design of test onground can keep away any mishandlings which are unavoidable for operators and make the process of test under control.

Key words: Payload, Manipulation validity, Access control, Mishandling shield, Manipulation log
