The International Reference Ionosphere (IRI), a joint project of URSI and COSPAR, is the de facto international standard for the climatological specification of ionospheric parameters …
NeQuick is a three-dimensional and time dependent ionospheric electron density model developed at the Aeronomy and Radiopropagation Laboratory of the Abdus Salam …
We introduce a novel empirical model to forecast, 24 h in advance, the Total Electron Content (TEC) at global scale. The technique leverages on the Global Ionospheric Map …
Abstract Space-based navigation and radar systems operating at single frequencies of< 10 GHz require ionospheric corrections of the signal delay or range error. Because this …

In Global Navigation Satellite Systems (GNSS) using L band frequencies, the ionosphere causes signal delays that correspond to link-related range errors of up to 100 m. Whereas …
The topside ionosphere modeling suffers from the relative scarcity of experimental electron density data. Different modeling approaches have been applied in empirical models, like IRI …
