Matlab codefor 软件定义 GPS 和伽利略接收器

本程序采用C++联合OPENGL编程实现了对太空中高速运行GPS卫星的星座进行显示，可以看到天空中24颗卫星的实际运行三维图

这个是程序用到的四颗可见星的所用的所有信息。其中给出7个可见星的信息，选则其中最好的四颗。请把信息内容复制到.txt中。-This is the program used four visible stars all of the information used. Which are given seven visible stars of information, the election is the best of four. Please copy the information content. Txt in.

从RINEX格式的GPS观测文件（即O文件）中分割提取想要的某段观测数据的C++程序-GPS observations from the RINEX format files (ie O file) to extract the desired data in a certain period of observation C++ program

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.

SIM868+STM32的定位代码,GPS,GPRS,并实现定位数据上传到OneNet平台，实现轨迹回放功能。

这个程序是用来构造的分形树的。其中的参数可以自由甚至。-This procedure is used to construct the fractal tree. The parameters can even free.

This document provides a good knowledge on how GPS receivers work

这是本人初次上载程序，请大家多多支持-谢谢 -GPS measurement data processing source, this is my first upload process, please everyone can support
