GNSS差分定位中的误差源分析
|
摘要
在卫星导航差分定位中,有多种误差因素影响定位精度。本文在介绍不同差分定位技术的基础上,分析了位置差分、伪距差分、载波相位差分三种差分方式的误差来源以及影响,并阐述了从单站差分拓展到网络差分,在扩大差分服务区、提高精度和完好性方面的优势,以及需要研究的问题。
In satellite navigation differential positioning, there are many error factors that affect the positioning accuracy. In this paper, different differential positioning techniques are introduced, and the sources of errors and their effects are analyzed.Furthermore, the advantages of improving accuracy and integrity are explained which expansion from single station differential to network differential, and give the issues that need to be studied.
