Abstract

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 realtime performance than the traditional Windows+1553B_PCI board solution is constructed. The realtime operating system μC/OSII is transplanted to BM3803, and the boardlevel support package for BM3803 is designed to ensure the onorbit software update and the task realtime. The software structure with high separation of user tasks and hardware is determined. When designing the user tasks of μC/OSII, 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 realtime performance, which can meet the realtime requirements of the highlevel satellite communication protocol.

Key words: BM3803, RTOS, reliability, realtime, 1553B, communication software, satellite ground detection platform
