针对GPS发射信号的捕获程序，采用差分相干捕获方法-Fired for GPS signal acquisition procedure, differential coherent acquisition method

利用实测的卫星星历数据、观测数据实现GPS单点定位，有差分参考数据，非常适合学习伪距单点定位(Using the measured data of satellite ephemeris and observation data, GPS single point positioning is realized, and there are differential reference data, which is very suitable for learning pseudo range

用于读取星历YUMA和生成天顶视图，其中main主文件，希望对GPS差分定位初学者有帮助。(It is used to read ephemeris YUMA and generate zenith view, and main master file, which is helpful for beginners of GPS differential positioning.)
