Ionosphere Model for European Region Based on Multi-GNSS Data and TPS Interpolation
Remote Sensing, 2017 The ionosphere is still considered one of the most significant error sources in precise Global Navigation Satellite Systems (GNSS) positioning. On the other hand, new satellite signals and data processing methods allow for a continuous increase in the ...

Monitoring the ionosphere based on the Crustal Movement Observation Network of China
Geodesy and Geodynamics, 2015 The Global Navigation Satellite System (GNSS) is becoming important for monitoring the variations in the earth's ionosphere based on the total electron content (TEC) and ionospheric electron density (IED).

Three-dimensional morphology of equatorial plasma bubbles deduced from measurements onboard CHAMP [PDF]
Annales Geophysicae, 2015 Total electron content (TEC) between Low-Earth-Orbit (LEO) satellites and the Global Navigation Satellite System (GNSS) satellites can be used to constrain the three-dimensional morphology of equatorial plasma bubbles (EPBs).

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study demonstrates the intriguing and complex interplay among auroral precipitation, enhanced TEC, density irregularities, and amplitude scintillations observed during the November 2025 superstorm. For the first time, we present observations of strong amplitude scintillation across continental United States (CONUS)—nearly from coast to ...

3D TOMOGRAPHY OF IONOSPHERIC ANOMALIES AFTER THE 2020 TURKEY EARTHQUAKE AND TSUNAMI USING GNSS-TEC [PDF]
Science of Tsunami Hazards, 2021 Global Navigation Satellite System (GNSS) satellite observations can obtain Total Electron Content (TEC) values in the ionosphere layer. The TEC value is obtained by decreasing the phase difference of the GNSS satellite’s two carrier waves (L-band).

Using GNSS TEC technique to observe compression of the plasmasphere by an interplanetary shock [PDF]
SCIENTIA SINICA Technologica, 2018 An interplanetary shock impinged on the Earth’s magnetosphere on 17 March 2015, and caused instant change of total electron content (TEC) measured by ground-based global positioning system (GPS) receivers. Hao et al. (2017) attributed the sudden TEC variation to magnetospheric compression by the shock, and in this paper we follow to examine the process
