| 摘 要： | 电离层作为近地空间环境的重要组成部分，对电波通信、卫星导航定位等都有重要影响。监测电离层形态结构有助于对电离层时空演化特征的理解及其建模和预测。随着全球导航卫星系统(global navigation satellite system，GNSS)的快速发展，GNSS电离层监测已成为重要的研究和应用方向。系统介绍了GNSS多维电离层监测及其应用的研究现状和进展，主要包括空基/地基GNSS联合反演电离层特征参数、层析技术反演电离层三维结构、电离层延迟建模、电离层异常扰动监测及机理认知等内容。

| Abstract: | Ionosphere is an important part of the near-earth space environment, and it has an important impact on radio communication, satellite navigation and positioning. Therefore, monitoring the ionospheric morphology is helpful to understand the spatiotemporal changes of the ionosphere and predict the ionospheric morphological characteristics. With the development of global navigation satellite system(GNSS), ionospheric monitoring has become an important research and application direction. This paper systematically introduces the research progress of multidimensional GNSS ionospheric monitoring and its application in related aspects. It mainly includes space-based/ground-based GNSS joint inversion of ionospheric characteristic parameters, tomography inversion of ionospheric three-dimensional structure, ionospheric delay modeling, ionospheric abnormal disturbance monitoring and mechanism cognition. |
