基于GPS技术测量误差的研究

Research on measuring error based on GPS technology

结合多年在输变电工程测量中GPS技术应用的实践,对多路径误差来源进行了定量分析,并对实测结果进行了比较,得出了多路径误差是影响GPS短基线测量精度的主要因素的结论。

Combining with many years application practical of GPS technology in power transmission project measurement,this paper made quantification analysis on multi-path errors sources,and compared the measured results,gained the multi-path errors were the main factor affected GPS short baseline measurement accuracy.
