摘　　要：讨论了GPS-OEM板的工作原理和通信协议,分析了NMEA-0183语句的数据格式,结合硬件特点提出了基于嵌入式系统的GPS数据采集系统的方案,给出了基于GPS-OEM板和单片机的数据采集系统的硬件设计方案和软件设计流程,实现对GPS全球定位系统的定位导航信息的接收和具体参数的提取。该系统体积小、功耗低、可运用于车辆的导航系统中,同时其设计思路对其他GPS-OEM板开发也具有很好的参考价值。The working principle and the communication protocol of GPS-OEM board are discussed and the data format of NMEA-0183 used in GPS-OEM is analyzed, According to the hardware a scheme of sampling GPS data system based on embeded system is put forward. The project of hardware design and the flow of software design of sampling GPS data system are presented, At the same time,the method of reading the navigation message is mentioned in general. The system designed by paper has the character of low power consume and volume,it can be used in the vehicle navigation and the scheme of the design is also suitable for other exploitation of GPS-OEMo
