kalman滤波用于GPS数据处理,本人已用过，非常好的源码-calman filter for GPS data processing，I have used, very good source

VB自己编写的卡尔曼滤波程序源代码，每次变化数据源触发该子函数，初始定义完后得出滤波数值，然后自动计算出K+1时刻最优偏差，然后赋值给text1 也就是最优偏差，一直变化，而这个迭代由数据源的变化而触发驱动。(The source code of the Kalman filter program written by VB. Every time the data source changes, the sub-function is triggered. After the initial
