Abstract The advantages, disadvantages and applications scopes of denoising methods are compared using wavelet filter, median filter and mean filter in the cases of different single noise pollution and mixing noise pollution using the GPS deformation monitoring data. Combining with the advantages of three filtering methods, an improved composite filtering method is proposed, which the wavelet filter is used firstly, and then the median filter and mean filter methods are applied. Theoretical analysis and practical applications verify that denoising effect of the improved method is better than tranditional methods.
