Abstract The effects of physical events on the ionosphere structure is an important field study, especially for navigation and radio communication. paper presents spatio-temporal ionospheric TEC response to recent annular solar eclipse June 21, 2020, which spans across two continents, Africa Asia, 14 countries. This took place same day as Solstice. Global Navigation Satellite System (GNSS) base...

In relation to satellite applications like global navigation satellite systems (GNSS) and remote sensing, the electron density distribution of the ionosphere has significant influence on trans-ionospheric radio signal propagation. In this paper, we develop a novel ionospheric tomography approach providing the estimation of the electron density’s spatial covariance and based on a best linear unb...
