An Antarctica‐to‐Spain HF ionospheric radio link: Sounding results
(Wiley, 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
(INGV, Istituto Nazionale di Geofisica e Vulcanologia, 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 ...
