| 摘 要： | 在利用全球导航卫星系统GNSS(GPS、GLONASS、Galileo等卫星定位系统)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。本文介绍了传统电离层模型的缺点,重点阐述了不同的电离层层析方法,同时分析了现在电离层层析方法所存在的主要问题,最后介绍了目前全世界电离层层析模型的研究展望。

| Abstract: | Ionospheric error is one of the main errors impacting precision of Global Navigation Satellite System (GNSS) in the GNSS-based precise navigation and orientation. In this paper, disadvantages of current ionospheric models were introduced. Different ionospheric tomography models were expatiated in detail. At the same time, existent issues of present ionospheric tomography were analyzed. In the end, development direction about tomography models was introduced especially. |
