    • A secure broadcast service for LDACS with an application to secure GBAS 

      Maurer, Nils; Caamaño Albuerne, María; Gerbeth, Daniel; Graupl, Thomas; Schmitt, Corinna (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Text en actes de congrés
      Accés obert
      The VHF Data Broadcast (VDB) data link is responsible for transmitting Ground Based Augmentation System (GBAS) corrections from the GBAS ground station to the aircraft. Thus, it is a major bottleneck for the evolution and ...

    • Airborne ionospheric gradient monitoring for dual-frequency GBAS 

      Gerbeth, Daniel; Caamaño Albuerne, María; Circiu, Mihaela-Simona; Felux, Michael (Curran Associates, Inc., 2022)
      Text en actes de congrés
      Accés obert
      Certified Ground Based Augmentation Systems (GBAS) as of today operate using only GPS signals in the L1 frequency band to enable precision approach guidance for landing aircraft. Ionospheric activity (i.e., scintillations ...

    • Detection of GNSS multipath with time-differenced code-minus-carrier for land-based applications 

      Caamaño Albuerne, María; Garcia Crespillo, Omar; Gerbeth, Daniel; Grosch, Anja (IEEE Press ; Wiley, 2020)
      Text en actes de congrés
      Accés obert
      Ground transportation systems demand accurate and robust localizationfunctions. Satellite navigation is considered a key element in those systems, but its position determination can be highly corrupted in urban environments ...

    • Improved ionospheric monitoring for future dual-frequency GBAS 

      Felux, Michael; Caamaño Albuerne, María; Circiu, Mihaela-Simona; Gerbeth, Daniel (2019)
      Text en actes de congrés
      Accés obert
      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; Juan Zornoza, José Miguel; Felux, Michael; Gerbeth, Daniel; González Casado, Guillermo; Sanz Subirana, Jaume (2021-02-11)
      Article
      Accés obert
      Large ionospheric gradients acting between a Ground Based Augmentation System (GBAS) reference station and an aircraft on approach could lead to hazardous position errors if undetected. Current GBAS stations provide solutions ...

    • 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)
      Text en actes de congrés
      Accés obert
      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. ...

    • Network-based ionospheric gradient monitoring to support ground based augmentation systems 

      Caamaño Albuerne, María (Universitat Politècnica de Catalunya, 2022-07-12)
      Tesi
      Accés obert
      The Ground Based Augmentation System (GBAS) is a local-area, airport-based augmentation of Global Navigation Satellite Systems (GNSSs) that provides precision approach guidance for aircraft. It enhances GNSS performance ...

    • Satellite selection in the context of an operational GBAS 

      Gerbeth, Daniel; Caamaño Albuerne, María; Circiu, Mihaela-Simona; Felux, Michael (2019-02-27)
      Article
      Accés obert
      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 ...
