摘　　要：基于小波分析理论,以RINEX级GPS数据预处理为视角,以提高单测站定位精度及基线解算质量为目的,采用VC++和MATLAB为开发平台,运用面向对象的编程方法,及动态连接库技术,实现了RINEX级GPS数据预处理软件GPSPPS.该软件实现了基于原始观测值信号、基于组合观测值信号和基于残差信号3种预处理模式.因软件采用了双层次的分解合成手段,从而可以独立于后处理软件.此软件已用于"中国大陆构造环境监测网络"基准站勘选中GPS数据的质量检查,取得了较好的效果.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 inde- pendent 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.
