整体式GNSS接收机多路径效应分析

Analysis of Multi-Path Effect on Integrated GNSS Receiver

探讨了GNSS接收机天线多路径效应的计算和分析方法,分别运用由多路径计算原理编制的数据分析软件和TEQC软件处理整体式GNSS接收机获取的数据,并进行对比分析,其结果说明多路径效应的大小与高度角存在线性关系。在实际数据预处理中,可通过分析软件代替TEQC,简单方便地获得站点的多路径信息,对站点的数据评定提供有效的质量信息。

This paper explored the calculation and analysis methods of the GNSS Receiver antenna multi-path effect,and used data analysis software which was developed by multi-path calculation principle and TEQC software to process the data obtained by the overall GNSS receiver.The analytical results show that the size of the multi-path effects and elevation angle there is a linear relationship.In the actual data preprocessing,the data analysis software instead of TEQC,can simply and conveniently obtain multiple path information sites,and provide effective quality information to site data evaluation.
