    • Contributions to the 3D ionospheric sounding with GPS data 

      García Fernández, Miquel (Universitat Politècnica de Catalunya, 2004-03-15)
      Doctoral thesis
      Open Access
      La tesi proposa una sèrie d'algoritmes destinats a obtenir informació del contingut d'electrons lliures presents a la ionosfera. El tipus de dades que s'utilitzaran seran bàsicament les corresponents a receptors de dades ...
    • Electron density extrapolation above F2 peak by the linear Vary-Chap model supporting new Global Navigation Satellite Systems-LEO occultation missions 

      Hernández Pajares, Manuel; García Fernández, Miquel; Rius Carrasco, Antoni; Notarpietro, Riccardo; von Engeln, Axel; Olivares Pulido, Germán; Aragón Ángel, Maria Angeles; García Rigo, Alberto (2017-08)
      Article
      Open Access
      The new radio-occultation (RO) instrument on board the future EUMETSAT Polar System-Second Generation (EPS-SG) satellites, flying at a height of 820 km, is primarily focusing on neutral atmospheric profiling. It will also ...
    • Precise ionospheric electron content monitoring from single- frequency GPS receivers 

      Hernández Pajares, Manuel; Roma Dollase, David; García Fernández, Miquel; Orús Pérez, Raul; García Rigo, Alberto (2018-10-01)
      Article
      Open Access
      The number of existing global positioning system (GPS) single-frequency receivers continues growing. More than 90% of GPS receivers are implemented as low-cost single-frequency chipsets embedded in smartphones. This provides ...
    • Study of several interpolation schemes to provide ionospheric corrections for navigation 

      Orús Pérez, Raül; García Fernández, Miquel; Prats Menéndez, Xavier; Hernández Pajares, Manuel; Juan, Miguel (2003-02)
      Conference report
      Open Access
      Since the development of space based geodesic techniques, the increasing of the positioning accuracy has been a major goal. In this context, the effect of the ionosphere has been a key issue to be taken into account to ...
