Application of tomographic ionospheric corrections in WADGPS networks for real-time estimation of integrated water vapour Hernández Pajares, Manuel; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; Colombo, Oscar L.; Van der Marel, Hans (Instituto de Navegacion de España, 2021)
Open AccessIn recent years several authors have developed strategies that estimate the Integrated Water Vapor (IWV), proportional to the Zenith Tropospheric Delay (ZTD), in near real time --i.e. with a delay of one hour or more--. ...

Ionospheric corrections for precise positioning with single-frequency GNSS receivers, a long distance away from the nearest network receiver Colombo, Oscar L.; Hernández Pajares, Manuel; Janssen, Volker (2015)
Restricted access - publisher's policyWe intend to present results of a study where precise ionospheric corrections have been generated and then used to assist Global Navigation Satellite System (GNSS) positioning with data from high-end single-frequency ...
Long-baseline (> 400Km) on the fly ambiguity resolution using ionospheric corrections with high geomagnetic activity Colombo, Oscar L.; Hernández Pajares, Manuel; Juan Zornoza, José Miguel; Sanz Subirana, Jaume (2001)
Open AccessA procedure for resolving carrier phase ambiguities, even under unfavorable geomagnetic conditions, has been tested. Precise ionospheric corrections have been made using dual-frequency data from control stations. Successful ...
Systematic detection of anomalous ionospheric perturbations above LEOs from GNSS POD Data including possible tsunami signatures Yang, Heng; Hernández Pajares, Manuel; Jarmolowski, Wojciech; Wielgosz, Pawel; Vadas, Sharon L.; Colombo, Oscar L.; Monte Moreno, Enrique; García Rigo, Alberto; Graffigna, Victoria; Krypiak-Gregorczyk, Anna; Milanowska, Beata; Bofill Soliguer, Pablo; Olivares Pulido, Germán; Liu, Qi; Haagmans, Roger (Institute of Electrical and Electronics Engineers (IEEE), 2022-06-13)
Open AccessIn this article, we show the capability of a global navigation satellite system (GNSS) precise orbit determination (POD) low Earth orbit (LEO) data to detect anomalous ionospheric disturbances in the spectral range of the ...
