目前GPS（全球定位系统）定位应用市场日趋成熟，正在进入应用的高速发展时期。本文以一款EverMore公司的GM-X205GPS接受模块为例，介绍了其数据格式，以及应用PIC16F874单片机RS232串口进行数据接收的程序-current GPS (Global Positioning System) location-based applications market becomes more mature, Applications are entering a period of rapid development. A EverMore paper to the GM-X205GPS accept modules for example, introduced a data format, and the application of PIC16F874 RS232 serial port for data receiving program

这个应该是台湾的一个文章，GPS相关MATLAB-this should be an article in Taiwan, GPS related MATLAB
