The 2021 la Palma volcanic eruption and its impact on ionospheric scintillation as measured from GNSS reference stations, GNSS-R and GNSS-RO
(European Geosciences Union (EGU), 2023-11-29)
Article
Accés obertIonospheric 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 ... -

(2016-11-16)
Report de recerca
Accés obertDuring the Beacon Satellite Symposium, held in Trieste, Italy, between June 26 and July 1 2016, the JRC chaired the session 5B: Radio Occultation Techniques and Measurements. The corresponding abstract of the session is ... -
The selection of basic functions for a time-varying model of unmodeled errors in medium and long GNSS baselines
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-10-19)
Article
Accés obertUnmodeled errors play a critical role in improving the positioning accuracy of Global Navigation Satellite Systems. Few studies have addressed unmodeled errors in medium and long baselines using their time correlation, ... -

Inter-system biases solution strategies in multi-GNSS kinematic precise point positioning
(2023-07)
Article
Accés obertEstimating inter-system biases (ISBs) is important in multi-constellation Global Navigation Satellite System (GNSS) processing. The present study aims to evaluate and screen out an optimal estimation strategy of ISB for ... -
Ionospheric scintillation models: An inter-comparison study using GNSS data
(IntechOpen, 2023-06-21)
Capítol de llibre
Accés obertExisting climatological ionosphere models, for example, GISM, SCIONAV, WBMOD, and STIPEE, have known limitations that prevent their wide use. In the framework of ESA study “Radio Climatology Models of the Ionosphere: Status ... -
Ionospheric scintillation anomalies associated with the 2021 La Palma volcanic eruption detected with Gnss-R and Gnss-Ro observations
(Institute of Electrical and Electronics Engineers (IEEE), 2022)
Text en actes de congrés
Accés restringit per política de l'editorialRecent studies have shown possible signatures or precursors of seismic activity in the ionosphere. Our group is focusing on ionospheric scintillation associated with seismic activity. By the time this study was conducted, ... -

Neural network based model for global Total Electron Content forecasting
(EDP Sciences, 2020-03)
Article
Accés obertWe introduce a novel empirical model to forecast, 24 h in advance, the Total Electron Content (TEC) at global scale. The technique leverages on the Global Ionospheric Map (GIM), provided by the International GNSS Service ... -
Comparison of GPS analysis strategies for high-accuracy vertical land motion
(2008-01)
Article
Accés obertTide gauges measure sea level changes relative to land. To separate absolute changes in sea level from vertical land movements tide gauges are often co-located with Continuous GPS (CGPS). In order to achieve an accuracy ... -
The ionosphere prediction service prototype for GNSS users
(EDP Sciences, 2019)
Article
Accés obertThe effect of the Earth’s ionosphere represents the single largest contribution to the Global Navigation Satellite System (GNSS) error budget and abnormal ionospheric conditions can impose serious degradation on GNSS system ...
