linux下select方式接受并解析NMEA协议gps信息，解析GGA、RMC语句，可以定位经纬度、时间、日期、星数等信息。

我在项目开发过程中搜集的各种NMEA协议文档，用于开发各种与GPS相关的项目。-I am in the project development process to collect a variety of NMEA protocol document for the development of a variety of GPS-related projects.

此程序为GPS接收机的源码，包括捕获、跟踪、定位解算和算法，以及NMEA协议，其硬件基于gp2015和gp2021,操作系统为linux，处理器为arm7,对理解GPS接收机原理有很大帮助．-This procedure source for GPS receiver, including the capture, tracking, positioning solvers and algorithms, as well as the NMEA protocol, and its hardwar

nmea语句解析代码，可以在Linux，单片机等平台上使用。(NMEA statement parsing code, you can use in Linux, SCM and other platforms.)
