Abstract: The realization of data bus interface of satellite load plays a vital role in the load flow of information transmission system, designing a reasonable data flow management scheme is vital for the normal communication between the satellite loads. MIL-STD-1553B bus has higher data transfer rate, real-time character, reasonable error control measures and special mode command, which is appropriate to the requirements of satellite because of its special environment and large amount of data transmission tasks. This paper configures the 1553B bus mode of satellite load through dragon chip and designs the data stream transmission form to realize the data bus interface of 1553B bus data flow.Test results show that, data interface has high reliability and effective practical application which meets the design requirements for satellite communication.

Key words: Satellite load, +1553B bus, +Data flow
