Abstract
The general processing procedure and models for CORS stations’ spatial deformation characteristic analysis are presented in this paper. The soft threshold filtering formula is deduced, which is for the Daubechies wavelet denoising, by utilizing the variance–covariance of Tianjin CORS baselines solution. The methods and models are adopted for Tianjin CORS datasets processing and the numerical results are calculated: the maximum annual deformation rate in U direction is up to 40 mm/yr, the accumulated deformation in plane and height direction are up to 84 and 400 mm separately. Based on the analysis, the suggestive updating frequency for Tianjin Geoinformation Reference Frame which sustained by Tianjin CORS should be 3–4 years in plane and 1 year in height. The experience and models can also be referenced by any other city CORS.
