    • AATR an ionospheric activity indicator specifically based on GNSS measurements 

      Juan Zornoza, José Miguel; Sanz Subirana, Jaume; Rovira Garcia, Adrià; González Casado, Guillermo; Ibáñez Segura, Deimos; Orús Pérez, Raul (2018-03-01)
      Article
      Open Access
      This work reviews an ionospheric activity indicator useful for identifying disturbed periods affecting the performance of Global Navigation Satellite System (GNSS). This index is based in the Along Arc TEC Rate (AATR) and ...
    • Accuracy of ionospheric models used in GNSS and SBAS: methodology and analysis 

      Rovira Garcia, Adrià; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo; Ibáñez Segura, Deimos (2016-03-01)

      Restricted access - confidentiality agreement
      © 2015, Springer-Verlag Berlin Heidelberg. The characterization of the accuracy of ionospheric models currently used in global navigation satellite systems (GNSSs) is a long-standing issue. The characterization remains a ...
    • Assessing the quality of ionospheric models through GNSS positioning error: methodology and results 

      Rovira Garcia, Adrià; Ibáñez Segura, Deimos; Orús Pérez, Raul; Juan Zornoza, José Miguel; Sanz Subirana, Jaume; González Casado, Guillermo (2020-01-01)
      Article
      Open Access
      Single-frequency users of the global navigation satellite system (GNSS) must correct for the ionospheric delay. These corrections are available from global ionospheric models (GIMs). Therefore, the accuracy of the GIM is ...

      Ibáñez Segura, Deimos; Rovira Garcia, Adrià; Alonso Alonso, María Teresa; Sanz Subirana, Jaume; Juan Zornoza, José Miguel; González Casado, Guillermo; López Martínez, Manuel (Multidisciplinary Digital Publishing Institute (MDPI), 2020-01-01)
      Article
      Open Access
      The present contribution evaluates how the European Geostationary Navigation Overlay System (EGNOS) meets the International Maritime Organization (IMO) requirements established in its Resolution A.1046 for navigation in ...
    • Experiments on the Ionospheric Models in GNSS 

      Vinh, La The; Quang, Phuong Xuan; García Rigo, Alberto; Rovira Garcia, Adrià; Ibáñez Segura, Deimos (2013)
      Conference report
      Open Access
      In GNSS, one of the main error sources of the Standard Positioning Service (SPS) is introduced by the ionosphere. Although this error can be cancelled by combining two signals at different frequencies, most of the ...
