摘　　要：随着科技的不断进步,全球卫星定位导航系统(GNSS)也在逐渐完善,为研究电离层工作提供了更好的平台。在GNSS观测中,电离层误差是影响观测结果的主要因素之一。因此,为了能够更好地掌握电离层的活动特性,根据相应原理,采用合理的方法进行电离层建模,从而提高观测的精度。本研究将结合电离层的相关结构和相关特性来对电离层建模的相关原理和方法进行分析,并介绍一些常用的电离层建模投影函数。Along with the advance of science and technology,the global satellite positioning and navigation System(GNSS) is gradually improved,providing a better platform for us to study the ionosphere activities.In GNSS observations and observation result of the ionosphere error is a major mistake. Therefore,the study and effective grasp of the activity characteristics of the ionosphere,and according to the corresponding principles to use reasonable methods for ionospheric modeling to improve the observation accuracy.This article will combine the related structure and characteristics of the ionosphere to related principle and method of the ionosphere modeling is summarized in this paper,and introduces some commonly used the ionosphere modeling projection function.
