TEC 浓度误差变化分析

摘要

电离层是大气层中的重要组成部分，但也是GPS测量误差中重要的影响因素，本文通过对电离层浓度分布研究，分析得出电离层的季节变化和在不同区域的变化趋势。%The ionosphere is an important part of atmospheric layer , but also is the important influencing factors in GPS measurement error, this article through to the ionosphere , the concentration distribution in the analysis of seasonal change of the ionosphere and the change trend in different areas .
