    • 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)
      Article
      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 ...

    • Breve introducción al sistema de posicionamiento europeo por satélite Galileo 

      Chillaron Farré, Enric (Escola Tècnica Superior d'Enginyers de Telecomunicació de Barcelona, 2002)
      Article
      Open Access

    • Design of a dual-band circularly polarized antenna for a Galileo Demonstrator 

      Nova Lavado, Enrique (Universitat Politècnica de Catalunya, 2009-02)
      Master thesis (pre-Bologna period)
      Open Access
      This Master Thesis presents the design of a novel antenna geometry for Galileo satellite navigation systems. This radiator is intended to improve the performance of an already designed antenna for the GALANT DLR’s internal ...

    • Fast LAMBDA-based ambiguity resolution combined with WARTK technique for Galileo data simulated using ESA's Galileo Signal Validation Facility 

      Odijk, Dennis; De Bakker, Peter; Verhagen, Sandra; Teunissen, Peter J. G.; Hernández Pajares, Manuel; Samson, Jaron (2009-12)
      Conference report
      Restricted access - publisher's policy
      This contribution addresses the effect of having a triple frequency Global Navigation Satellite System (GNSS) on ambiguity resolution of long baselines, i.e. baselines for which the differential ionospheric delays cannot ...

    • Galileo ionospheric correction algorithm: an optimization study of NeQuick-G 

      Aragón Ángel, Maria Angeles; Zürn, M.; Rovira Garcia, Adrià (2019-11-24)
      Article
      Open Access
      At present most low-cost GNSS receivers operate one frequency in the L band. For themone of the largest error contributions is the delay of radio signals in the Ionosphere. NeQuick-Gisthe official ionospheric correction ...

    • Galileo Signal Generation. Simulation Analysis 

      Canalda Pedrós, Roger (Universitat Politècnica de Catalunya, 2009-04)
      Master thesis (pre-Bologna period)
      Open Access
      This work presents the navigation signals and their allocation in the radio frequency band used in the new European Global Navigation Satellite System (GNSS): Galileo. All signals are described mathematically and then ...

    • Sistema Galileo : El concepto europeo de navegación por satélite 

      Martínez Tébar, Juan Antonio (Universitat Politècnica de Catalunya, 2013-07)
      Master thesis (pre-Bologna period)
      Open Access

    • Survey of Positioning Techniques for improved Accuracy
