摘要

This article describes the basic principles of the wavelet analysis technology for GPS deformation signal processing. According to the basic property of wavelet function, combined example of GPS deformation signal that contain a small amount of gross errors, this article studies the display law of characteristics of gross errors in different scales after wavelet transform and the problem how we determine its location. This paper analyzes the influences of regularity and the number of decomposed layers when we want to identify the gross errors in the dynamic monitoring data. This research has provided basis for selecting proper wavelet function to identify gross errors.
