Description: 国外开发的GPS实用工具，值得借鉴！
这是一套三的程序，可以读取GPS NMEA位置数据，以及做各种各样的事情，如下：
-将作为一个GPS接收器simulate.exe位置并输出数据到串行端口。你可以选择一个位置/速度/方向或者你可以重放记录的位置数据。我用这个广泛的其他程序来读取GPS位置数据在发展。你可以使用两个物理串行端口和一个零调制解调器电缆，或虚拟串口与零调制解调器的配置。

capture.exe NMEA数据记录-将在稍后的时间分析或处理一个文件。也可以去一些指定的时间长度，或登录不断。
- process.exe会读NMEA日志文件和计算的统计数据。这是主要用于静态精度检验，但可用于快速在一些操作看卫星可见性。由此产生的数据保存为图像，并有一个htm文件来显示它们。-This is a suite of three programs that are designed to do various things with GPS NMEA position data.
- Simulate.exe will act as a GPS receiver and output position data to a serial port. You can a location/speed/direction or you can have it replay some recorded position data. I use this extensively during the development of other programs that are designed to read GPS position data. You can use two physical serial ports and a null modem cable, or virtual serial ports with a null modem configuration.

- Capture.exe will record NMEA data to a file for analysis or processing at a later time. It can go for some specified length of time, or log continually.
- Process.exe will read a NMEA log file and calculate statistical data on it. This is used primarily for static accuracy testing, but could be used to quickly see satellite visibility during some operation. The resulting data is saved as images, and there is a .htm file to display
