Wavelet analysis was used as a tool to improve GPS data quality of single station on RINEX level.Preprocessing software GPSPPS was programmed by using object oriented method,dynamitic link library technology in VC++ and MATLAB.The software realized three preprocessing models presented.They are respectively based on raw observations,linear combination observations and observation residuals of point positioning.The software adopted double layer-decomposition and composition methods,which made it independent of post software.The software has been used in the quality inspection of GPS data in the base-station selected by the project continental-tectonic environmental monitoring system in China,and achieved good results.
