Abstract

Based on the analysis on the characteristics of RS485 and 1553B bus, a bus system of 1553B protocol over RS485 transceivers is introduced, which can reduce the mass, size and power of spacecrafts when applied in space missions. Design of a RS485-to-1553B bus bridge is proposed here to realize the interoperation between 1553B bus and RS485 bus, which is easy to implement over FPGA and take up little hardware resources. Hardware design and logic design in FPGA of the bus bridge are described in detail, and the high reliability methods adopted are introduced also. The test results prove the validity and reliability of the bridge design. The RS485-to-1553B bus bridge can be used in the Assembly, Integration and Test processes of satellites.
