On the basis of wavelet threshold noise reduction model, we researched and analyzed three kinds of noise reduction methods, they were the hard threshold and soft threshold and improved threshold. We based on the features of GPS dynamic deformation monitoring data sequence, combined with the measured data and respectively used three kinds of noise reduction threshold model to do experiments and analyzed the effect of different threshold selection to the noise reduction. Experimental results showed that the improved model of the noise reduction threshold value was better than the other two methods and can effectively identify the trends.
