摘　　要：介绍了一种基于ARM的卫星定位接收机的实现;北斗二代卫星定位接收机作为一种高实时性嵌入式系统应用,在操作系统使用上,利用RTAI(Real Time ApplicationInterface)对嵌入式Linux内核进行实时性扩展,组成双内核系统,再整合实时任务的应用模块一起实施于基于ARM9处理器的接收机硬件平台;通过实验验证,其满足了新一代卫星定位接收机的实时性要求。An implementation of ARM-based COMPASS receiver is introduced. As an application of high performance Embedded System, the second generation COMPASS receiver needs higher real-time requirement. RTAI （Real Time Application Interface） is used here as an extension of embedded Linux kernel which is refined with real- time application task module, the double kernel software mode of RTAI ＆ Linux＇s combination is implemented on an ARM9-based flexible configured and feasible multi-functional receiver hardware platform. With validation, the needs of real-time requirement on the new generation COMPASS receiver can be met on using this software mode; the receiver system achieves great promotion on most performance.
