  • 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
