Abstract: Multitask processing is a crucial aspect in the design of Beidou navigation receiver. This paper interprets the means of embedded real-time operating system μC/OS-Ⅱ,completes multitask processing and communicating between tasks, resolves the problem of real-time performance and stability. Study、multitask compartmentalizing and communicating between tasks using message queue. The experimental results shows uc/os II can meet the need of system.
