      Article
      Accés obert
      Global navigation satellite system (GNSS) satellites are equipped with very stable atomic clocks that can be used for assess-ing the models and strategies involved in the estimation processes, where the clock estimates ...

    • Revisit the calibration errors on experimental slant total electron content (TEC) determined with GPS 

      Nie, Wenfeng; Xu, Tianhe; Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo; Chen, Wu; Xu, Guochang (2018-06-26)
      Article
      Accés obert
      The calibration errors on experimental slant total electron content (TEC) determined with global positioning system (GPS) observations is revisited. Instead of the analysis of the calibration errors on the carrier phase ...

    • The 2021 la Palma volcanic eruption and its impact on ionospheric scintillation as measured from GNSS reference stations, GNSS-R and GNSS-RO 

      Molina Ordóñez, Carlos; Boudriki Semlali, Badr Eddine; González Casado, Guillermo; Hyuk, Park; Camps Carmona, Adriano José (European Geosciences Union (EGU), 2023-11-29)
      Article
      Accés obert
      Ionospheric disturbances induced by seismic activity have been studied in recent years by many authors, showing an impact both before and after the occurrence of earthquakes. In this study, the ionospheric scintillation ...

    • The Geodetic Detrending technique: enabling high-accuracy navigation under scintillation 

      Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Scintillation is a particular type of space weather perturbation occurred when the signals from the Global Navigation Satellite System (GNSS) traverse irregularities in the ionosphere; the upper layer of the Earth atmosphere. ...
