Kalman Filtering Model of Dynamic Deformation Based on Wavelet Analysis

By analyzing the data obtained by GPS in dynamic deformation, wavelet analysis is used to filter GPS data of dynamic deformation, distill deformation character and separate different frequency of deformation.Then this paper puts forward the research on Kalman filtering model of dynamic deformation based on wavelet analysis, through combining wavelet analysis with Kalman filtering. The result of the united model is advantageous to enhance and improve GPS data accuracy and its effect is notable, which indicates the superiority to single deformation model.
