GPS 定位系统，不错的介绍。可以了解GPS的只是-GPS positioning system, a good introduction. GPS can understand only

GPS单点定位的滤波程序，可以获得速度信息和位置信息,实现卫星坐标计算，地面点坐标计算，精度指标计算和输出到Excel。

一个基本的类 用于提取GPS数据中的经纬度，速度高度信息，功能较简单。-A basic category for the extraction of GPS data in latitude and longitude, speed, height information, a simpler function.

gps matlab 仿真程序（A collection of geodetic functions that solve a variety of problems in geodesy. Supports a wide range of common and user-defined reference ellipsoids. Most functions are vectorized.）-gps matlab simulation program (A collection of geodetic functions that solve a variety of problems in geodesy.
