Based on the stm32+mc20 gps positioning system, the 32 serial port control 20 sends the AT command and uploads it to the platform via http.

说明：  将大地经纬度坐标转换为地球地心直角坐标的函数。(Geodetic latitude and longitude coordinates will be converted to the Earth)

uniguard gps tracker protocol

车子里程记录表，用GPS经纬度计算距离，驱动LCD显示(Car mileage record sheet, calculate the distance by GPS latitude and longitude, driven LCD display)

GPS选星算法，选择几何形状最好的卫星组合(GPS satellite selection algorithm to select the best geometry of the satellite portfolio)

JT808-GPSServer (1).GPS系统可以学习下(JT808-GPSServer (1). GPS systems can learn)

用于惯导卫星导航组合松组合程序，有实际的采集数据(INS/GPS this is a program than INS/GNSS integrated)

本代码是根据GPS数据解析代码经修改适用于北斗数据的解析(This code is a modification applies to Compass data analysis based on GPS data parsing code by)

说明：  输入一天内的小时和分钟以及阶数，自动读取精密星历文件，Neville插值在所给阶数数据中间精度最高，所以会自动选择精度最高的情况插值。替换目录下sp3文件即可完成修改。(Input the hour, minute and order of a day, and automatically read the precise ephemeris file. Neville interpolation has the highest accuracy among the given order data, so it will automatically select the case with the highest accuracy. Replace the SP3 file in the directory to complete the modification.)
