The widely used GNSS correction services for high precision positioning take advantage of
accurate real-time TEC forecasting based on vertical total electron content (VTEC) maps …

Ionospheric models are applied for computing the Total Electron Content (TEC) in
ionosphere to reduce its effects on the Global Navigation Satellite System (GNSS)-based …

Vertical total electron content (VTEC) has great importance in describing the ionosphere.
VTEC values are commonly distributed in regular grids by means of so‐called global …

The ionospheric information retrieved from the Doppler Orbitography and Radiopositioning
Integrated by Satellite (DORIS) system provides valuable and external data sources to …

This work presents a new method for assessing global ionospheric maps (GIM) using
ionosonde data. The method is based on the critical frequency at the F2 layer directly …

The ionosphere is one of the main error sources in positioning and navigation; thus,
information about the ionosphere is mandatory for precise modern Global Navigation …

The ionosphere is one of the largest error sources in GNSS (Global Navigation Satellite
Systems) applications and can cause up to several meters of error in positioning. Especially …

The ionospheric mapping function (MF) is used to achieve mutual conversion between the
vertical total electron content (VTEC) and the slant total electron content (STEC) and is vital …

The vertical total electron content (VTEC) is one of the key quantities to describe variations
of the ionosphere and can be provided to users to correct the ionospheric disturbances for …

The ionospheric variabilities are influenced by various drivers, and quantifying their relative
contributions is beneficial to ionospheric modeling and ionospheric forecasting, but this is …
