利用卡尔曼滤波实现的GPS动态定位的程序，可以获得速度和位置-Using the GPS Kalman filter is the dynamic positioning of the program, get the speed and position

基于车载导航gps的4维（北东方向的位置及速度）模型。搭建精确地kalman滤波模型！-Based on four-dimensional (position and velocity to the North East) model of car navigation gps. Kalman filter model to build accurate!
