Abstract: Inter-satellite data transmission system requires space-borne equipment with real-time data transmission, high accuracy, and the data transfer process must remain beat sync.Space-borne equipment related must conduct rigorous pre-launch data stream tests to ensure meet the requirements, so building data stream test system on the ground has great significance.This paper makes the secondary development based on 1553B bus simulation card and completes the design of ground testing system. The test results for related space-borne equipment show that this system has realized several kinds of transmission mode with 1553B bus, such as BC-RT (Bus Controller-Remote Terminal), RT-BC (Remote Terminal-Bus Controller), RT-RT, MT (Monitoring Terminal), and completed the transmitting procedure with given amount of data during the limited period. In a word, the system designed in this paper satisfies the tempo synchronous for data transmission and completes the data stream testing for the relevant space-borne equipment. The system can not only meet the test requirements for related space-borne equipments, but also can be regard as a general platform for the data stream testing and thus provides data level test method with 1553B bus.
