根据GPS卫星的广播星历，计算卫星的位置

解析GPS 串口的NMEA报文的类。有GGA,GSA,GSV,RMC,RMB等报文的解析-GPS NMEA CLASS

gps的开发程序，出自吉大的高手，gis开发是目前非常有前途的一个方向。-the development process, from the Kyrgyzstan big players and gis development is a very promising direction.

用Matlab仿真turbocode的算法，即编码结构-using Matlab turbocode algorithm, namely coding structure

用matlab实现的超宽带物理层的仿真 。-Using matlab to achieve the ultra-wideband physical layer simulation.

实现网络GPS定位车辆的位置-Let you kown how to get your position in gps network

精密星历是按照15min的间隔给出卫星位置，要想获取任意时刻卫星的位置，必须对精密星历进行内插，本程序实现了通过读取SP3文件，对卫星的星历进行内插计算。

基于部标808协议的GPS平台压力测试工具，通常用于平台压测用，检测GPS服务器解析平台测试压力的工具

The idea behind differential GPS is to remove as much errors as possible from the range measurements by establishing these errors at a reference site. In its most simple setup, a GPS receiver is located at a well surveyed position and its (pseudo) range measurements are compared with the actual calculated range from this receiver to the SV s. The differences between measured ranges and calculated ranges at the reference receiver are applied as corrections to the ranges measured by other receiver(s) close by.

该程序是同步中的相位估计方法，该方法可以估计不同参数下的相位大小。-synchronization is the process of phase estimation method, which can be estimated under different parameters of phase size.
