Application of Kalman Filter Method to the Date Processing of GPS Deformation Monitoring

As a dynamic data processing method, Kalman filter is widely applied in deformation monitoring data processing. Kalman filter can effectively remove the noise to extract the real deformation information. It's a process of anticipation and amendment constantly. In the solution, a new state of the system can be got by the use of new observation values, and it is convenient to the real-time processing of observations. In this paper, GPS deformation monitoring data is processed by recursive Kalman filter. The method works well in eliminating the noise with evident effect, which has certainly profits to processes the monitor data of distortion by GPS .
