    • 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 ...

    • Low Rate High Frequency Data Transmission from Very Remote Sensors 

      Bergadà Caramés, Pau; Alsina Pagès, Rosa Maria; Vilella Parra, Carles; Regué, Joan Ramon (Remote Sensing - Advanced Techniques and Platforms, 2012-06)
      This chapter deals with the difficulties of transmitting data gathered from sensors placedin very remote areas where energy supplies are scarce. The data link is established bymeans of the ionosphere, ...

    • 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 ...
