摘　　要：在利用全球导航卫星系统GNSS进行精密定位和导航时,电离层延迟误差是影响其精度和准确度的主要误差源之一,故对电离层模型研究至关重要。本文将电离层模型分成了经典电离层模型和现代电离层模型,并对经典电离层模型进行了比较,重点介绍了目前全世界电离层模型的研究热点、存在问题及研究方向。Ionospheric error is one of the main errors impacting precision of Global Navigation Satellite System （GNSS） when it is used in precision navigaton and orientation. So it is very important for us to study ionospheric models. In this paper, ionospheric models are divided into classic model and modernistic models. At the same time, classic models are compared by each other. In addition, hot topics, existing problems and development direction about current ionospherec models is introduced especially.
