一个很不错的GPS接收机源程序，各项功能齐全

--收集的-----vc++mapx资料------ 给大家--- collected----------- vc MapX information for everyone to s

gps接收端源码以及1个test列子，提供简单的经纬度，速度，时间等GPS数据信息-gps receiver as well as a test source Liezi, providing a simple latitude and longitude, speed, time GPS data

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卫星定位源码 用VB做的，可以研究一下！-GPS satellite positioning with VB source code to do, you can look!

GPS应用程序设计，内含GPS卫星原理、方法及详细源代码-GPS application design, including GPS satellite theory, method and detailed source code

关于GPRS的通讯程序,对GPRS协议及软件实现的功能得到了很大的加强.要好好研究啊.-on GPRS communication procedures, GPRS agreement and the right software to function much strengthened. We should carefully study ah.

the example file that can decode the NMEA protocol

MO中利用图片生成点符号专题　 deskfee 发表于 2005-3-15 14:34:24 用truetype字体可以比较方便的实现点符号，但用图片可以实现更加漂亮的点符号（如果你认为你做的图标足够漂亮的话，^_^），只是实现起来麻烦一点。 文件是txt,下载完后请先更改-MO use photographs to generate symbols deskfee topic published in 2005-3-15 14:34:24 truetype fonts can be used to facilitate the realization of more symbolic point, but pictures can be used to achieve a more beautiful symbol of the point (if you think you have done enough beautiful icon, ^ _ ^), but is only one point up trouble.

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
