GPSR 6.0

在测绘领域根据需要需要进行多种坐标系之间转换，常用的坐标系包括BJ54，西安80，WGS84.CGCS2000，七参数转换，本程序实现了北京54到当地坐标系，西安80到当地坐标系，以及当地坐标系到北京54与西安80之间的相互转换等

GPS信号捕获程序,采用串行搜索算法,并自带三段中频采样的数据.-GPS signal acquisition procedures, using serial search algorithm, and bring their own copies of the three IF sampling data.

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
