    • A comprehensive sounding of the ionospheric HF radio link from Antarctica to Spain 

      Ads, Ahmed Gamal; Bergadà Caramés, Pau; Vilella Parra, Carles; Regué, Joan Ramon; Pijoan Vidal, Joan Lluís; Bardají Benach, Raúl; Mauricio Ferré, Juan (Radio Science, 2013. Vol.48, 1, Gener - Febrer, 2013-01)
      Since 2003, our group has been investigating the performance of different transmission techniques for low-power low-interference High Frequency (HF) ionospheric communication systems. Specifically, we ...

    • An Antarctica‐to‐Spain HF ionospheric radio link: Sounding results 

      Vilella Parra, Carles; Miralles Esteban, David; Pijoan Vidal, Joan Lluís (Radio Science, 2008, Vol.43 ,Nº4 (Agost), 2008-08)
      Our research group in Electromagnetism and Communications is involved in a project dealing with the channel characterization of an ionospheric radio link from the Spanish Antarctic Base (62.6°S, 60.4°W) ...

    • An example of operation for a partly manned Antarctic geomagnetic observatory and the development of a radio link for data transmission 

      Torta Margalef, Joan Miquel; Marsal Vinadé, Santiago; Riddick, John C.; Vilella Parra, Carles; Altadill Felip, David; Blanch Llosa, Estefania; Cid, Oscar; Curto, Joan J.; De Santis, Angelo; Gaya-Piqué, Luis R.; Mauricio Ferré, Juan; Pijoan Vidal, Joan Lluís; Solé, Germán J.; Ugalde, Arantza (Annals of Geophysics, 2009. Vol. 52, 1 (Febrer), 2009-02)
      The experience acquired from more than ten years of operation of an Antarctic geomagnetic observatory is described along with the development of data transmission facilities. The observatory was deployed ...

    • Vertical and oblique ionospheric soundings over a very long multihop HF radio link from polar to midlatitudes: Results and relationships 

      Vilella Parra, Carles; Miralles Esteban, David; Altadill Felip, David; Acosta Pérez, Francisco; Solé, J.G.; Torta Margalef, Joan Miquel (Radio Science, 2009. Vol. 44, Rs2014, 2009-04)
      A vertical incidence sounder (VIS) was installed at the Spanish Antarctic Base (62.7°S, 299.6°E) during the Antarctic summer survey 2004–2005. In addition, an oblique sounding (OS) system for HF ...
