说明：  北斗GPS双模定位模块，串口解析协议后直接输出(Beidou GPS Dual-mode Positioning Module, Direct Output after Serial Port Resolution Protocol)

该程序基于MATLAB平台编写，实现了GPS/INS基于位置松组合的卡拉曼滤波算法，分为两部分，GPS_INS.m为组合算法主文件，输入捷联惯导平台实测数据，设置各量测噪声参数，在调用卡尔曼滤波函数进行数据融合校正，最后实现绘图功能；kalman_GPS_INS.m 为卡拉曼滤波程序，输入量测误差以及各噪声参数可得位置和速度估计值。(The program is based on MATLAB platform, and realizes the Kalman filtering algorithm of GPS/INS based on position loosening combination. It is divided into two parts. GPS_INS.m is the main file of the combined algorithm, inputs the measured data of the strapdown inertial navigation platform, sets the measurement noise parameters, and carries out data fusion correction by calling the Kalman filter function, and finally realizes the drawing. Function; kalman_GPS_INS.m is Kalman filter program, input measurement error and noise parameters can be estimated position and velocity.)

说明：  本程序适用于Gps坐标系和北京54或西安坐标系的转换，也可以应用与Gps坐标系和Cgs2000坐标系的坐标转换。(the procedures applicable to the PON coordinates and Beijing or Xi'an 54 coordinate system conversion, and the application can also coordinates and PON Cgs2000 coordinates the coordinate transformation.)

生成北斗B1I路信号扩频码，完成北斗B1I路扩频信号仿真及接受仿真(Generate Beidou B1I signal spread spectrum code, and complete the Beidou B1I road spread spectrum signal simulation)

How to convert GPS readings in Degree, Minutes Seconds to Decimals

GPS串口采集程序，基于VC++ MFC，非常不错的资源，采用多线程实现。(GPS serial acquisition program, based VC++ MFC, very good resources, using multithreading.)

说明：  这是一个用c#实现的GPS定位系统软件，你只需输入所要查询的城市名就会连接到地图，你可以对其执行放大，缩小，左移，右移，上移，下移等操作，非常实用，绝对值得，希望对您有帮助 (A software about the GPS positioning system.You can search for a city which is linked to the map,just by inputting the name,and also you could make it bigger,smaller,move left,right,up and down.You won t miss it.)
