Abstract
In view of the fact that the payload ground test system is too difficult to support the test of the rapid mode-switch payload,this paper proposes a method of time synchronization between satellite and ground for the payload ground test system.This method synchronizes the time between the ground test system and the satellite with the frequency of the telemetry which is broadcasted in the test local area network,and makes the state of the ground test system match precisely with the payload work-mode according to the telecommand.The synchronization provides the state records of the ground test system with the time labels,and the records are the input conditions for the check of the payload data.The method can be realized easily and applied widely,which provides reference for the design of the ground test system which demands the synchronization between satellite and ground test system.关键词
