Abstract: processor is used in a satellite ground detection equipment to simulate the bus controller in the satellite in order to detect the remote terminal, and a satellite data simulation platform with stronger realtime performance than the traditional Windows+1553B_PCI board solution is constructed. The realtime operating system μC/OSII is transplanted to BM3803, and the boardlevel support package for BM3803 is designed to ensure the onorbit software update and the task realtime. The software structure with high separation of user tasks and hardware is determined. When designing the user tasks of μC/OSII, the verification functions of BM3803 and B61580 are fully utilized to improve the software reliability. Finally, the same user task is completed with this design and the Windows+1553B_PCI board solution respectively, and the design has better realtime performance, which can meet the realtime requirements of the highlevel satellite communication protocol.
Key words: BM3803, RTOS, reliability, realtime, 1553B, communication software, satellite ground detection platform
