    • Improved ionospheric monitoring for future dual-frequency GBAS 

      Felux, Michael; Caamaño Albuerne, María; Circiu, Mihaela-Simona; Gerbeth, Daniel (2019)
      Conference report
      Open Access
      As of today, all Ground Based Augmentation Systems operate using only the navigation signals from GPS (and Glonass for a number of stations in Russia) in the L1 band. Ionospheric activity, especially in equatorial and polar ...
    • Network-based ionospheric gradient monitoring to support GBAS 

      Caamaño Albuerne, María; Felux, Michael; Gerbeth, Daniel; Juan Zornoza, José Miguel; González Casado, Guillermo; Sanz Subirana, Jaume (ION Publications (The Institute of navigation), 2019)
      Conference report
      Open Access
      Ionospheric anomalies, like large ionospheric gradients, might produce a difference between the ionospheric error experienced bythe Ground Based Augmentation System (GBAS) reference station and the aircraft on approach. ...
    • Satellite selection in the context of an operational GBAS 

      Gerbeth, Daniel; Caamaño Albuerne, María; Circiu, Mihaela-Simona; Felux, Michael (2019-02-27)
      Article
      Open Access
      When incorporating multiple constellations into future ground based augmentation systems (GBAS), a problem with limited VDB (VHF data broadcast) capacity might arise. Furthermore, the number of airborne receiver tracking ...
