| 摘 要： | 利用Matlab二次开发编制teqcplot程序模块,实现质量检查结果的图形显示和可视化查询,将GPS观测数据中存在的电离层延迟和多路径效应的影响定量地表示出来,提高了数据处理的工作效率。并用实测数据进行验算,根据检查结果对GPS观测数据进行相应的处理,通过对比分析结果表明,经TEQC预处理后的观测数据,有效地提高了GPS基线解算的质量。

| Abstract: | TEQC is a powerful GPS/GLONASS data pre-processing software,but it is not ideal to make quality checking of GPS observation data visible.This paper establishes the teqcplot program module using matlab secondary development,realizing the quality checking result graphical display and visualization inquiries,coming out the quantitative of ionospheric delay and multipath effects in GPS data.And checking calculation with measured data,the data is edited according to the checking result,by contrasting,the result showed that GPS resolution quality was improved. |
