论文摘要
本文强调了纳维奇在印度次大陆地区的电离层研究中的表现。该研究是使用IIT Indore的一年（2017-18）的数据进行的，IIT Indore是赤道电离异常（EIA）附近的位置。人们已经观察到，即使没有单个错误校正，结果也位于1 \ ensureMath {^{\ circ}} x 1 \ ensureMath {^{^{^{^{^{^{^{^{\ circ}}网格中，围绕GPS VTEC估计的iPP估计的1 \ ensuremath {^{\ circ}} x 1 \ ensuremath {^{\ circ}} x 1 \ ensuremath {^{\ circ}} x 1 \ pm20 \％$的结果。此外，还提出了在同一地点的两次不同的地磁风暴（2017年9月8日和28日）中的电离层响应，并还提出了其他使用GPS和NAVIC覆盖印度次大陆的IGS站。该分析表明，在2017年9月的地磁风暴期间，TEC发生了类似的变化，表明Navic对研究太空天气事件的适用性以及印度次大陆的电离层研究。
This paper emphasizes on NavIC's performance in ionospheric studies over the Indian subcontinent region. The study is performed using data of one year (2017-18) at IIT Indore, a location near the northern crest of Equatorial Ionization Anomaly (EIA). It has been observed that even without the individual error corrections, the results are within $\pm20\%$ of NavIC VTEC estimates observed over the 1\ensuremath{^{\circ}} x 1\ensuremath{^{\circ}} grid of IPP surrounding the GPS VTEC estimates for most of the time. Additionally, ionospheric response during two distinct geomagnetic storms (September 08 and 28, 2017) at the same location and other IGS stations covering the Indian subcontinent using both GPS and NavIC has also been presented. This analysis revealed similar variations in TEC during the geomagnetic storms of September 2017, indicating the suitability of NavIC to study space weather events along with the ionospheric studies over the Indian subcontinent.
