Ionospheric TEC modelling for earthquakes precursors from GNSS data
Quaternary International, 2017Abstract In present study, we measured the Total Electron Content (TEC) variation in the ionosphere from Global Navigation Satellite System (GNSS) data which might have been induced by earthquakes in the Himalayan region. The results were analysed with other inducing factors (geomagnetic storm and solar flare) affecting TEC in order to constraint the

Correlation between Ionospheric TEC and the DCB Stability of GNSS Receivers from 2014 to 2016
Remote Sensing, 2019 The Global Navigation Satellite System (GNSS) differential code biases (DCBs) are a major obstacle in estimating the ionospheric total electron content (TEC).

The TEC-GNSS analysis of the paroxysmal eruptive activity of Mt.Etna
2023The ionosphere is a region of the upper atmosphere (50-1000 km a.s.l.) characterized by free electrons and ions produced mainly by solar radiations (UV, X) and subordinately by cosmic radiations (RAVANELLI, 2021). It’s a very sensitive plasma to energy variations, mostly the F2 layer (240-400 km a.s.l.) that is a region of maximum ionization ...

A Transformer Model for Ionospheric TEC Prediction Using GNSS Observations
2023Precise modeling of the ionospheric Total Electron Content (TEC) is critical for reliable and accurate GNSS applications. TEC is the integral of the location-dependent electron density along the signal path and is a crucial parameter that is often used to describe ionospheric variability, as it is strongly affected by solar activity.

GNSS derived TEC data ingestion into IRI 2012
Advances in Space Research, 2015Abstract Experimental vertical total electron content (VTEC) data given by Global Ionospheric Maps (GIM) has been ingested into the IRI version 2012, aiming to obtain grids of effective input parameter values that allow to minimize the difference between the experimental and modeled vertical TEC.

Periodicities in Global Mean TEC from GNSS Observations
Earth, Moon, and Planets, 2008As an important measurement parameter, global total electron content (TEC) is appropriate for the study of the Sun–Earth connection. In this paper, the wavelet technique is employed to investigate the periodicities in global mean TEC during 1995–2008.

The Effect of GNSS Sites Distribution on TEC Derivation
2016With worldwide increased Global Navigation Satellite System (GNSS) receivers, it is possible to obtain the ionospheric total electron content (TEC) and hence monitor the ionosphere with GNSS. Using a thin layer assumption of the ionosphere and dual-frequency Global Positioning System (GPS) observations from 16 geomagnetically quiet days in four seasons
