Mitigation of receiver biases in ionospheric observables from PPP with ambiguity resolution
(2020-04-15)
PPP (Precise Point Positioning) is a GNSS (Global Navigation Satellite Systems) positioning method that requires SSR (State Space Representation) corrections in order to provide solutions with an accuracy of centimetric ...
Towards forecasting and mitigating ionospheric scintillation effects on GNSS
(Ieee, 2007-01-01)
The effect of the ionosphere on the signals of Global Navigation Satellite Systems (GNSS), such as the Global Positionig System (GPS) and the proposed European Galileo, is dependent on the ionospheric electron density, ...
Seasonal analysis of Klobuchar and NeQuick G single-frequency ionospheric models performance in 2018
(2020-01-01)
For single frequency positioning, the ionospheric effects can be minimized by using an ionospheric model, e.g., the Klobuchar or the NeQuick G. These models, respectively associated with the Global Positioning System (GPS) ...

Assessment of a TEC calibration procedure by single-frequency PPP
(2018-04-01)
Global navigation satellite system (GNSS) measurements have become an outstanding data source for ionospheric studies using total electron content (TEC) estimation procedures. Many methods for TEC estimation had been ...
A real‐time forecast service for the ionospheric equatorial zonal electric field
(American Geophysical Union, 2012-09-18)
The zonal electric field is the primary driver of two important features of the equatorial ionosphere: (1)The Equatorial Ionization Anomaly (EIA), and (2) plasma density irregularities, also known as spread‐F. During ...
Ionospheric TEC Weather Map Over South America
(Amer Geophysical Union, 2016-11-01)
Ionospheric weather maps using the total electron content (TEC) monitored by ground-based Global Navigation Satellite Systems (GNSS) receivers over South American continent, TECMAP, have been operationally produced by ...
