An Antarctica‐to‐Spain HF ionospheric radio link: Sounding results
(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) ... -
Analysis of the Ordinary and Extraordinary Ionospheric Modes for NVIS Digital Communications Channels
(Sensors, 2021, 21 (6), 2021-03)Sensor networks have become more popular in recent years, now featuring plenty of optionsand capabilities. Notwithstanding this, remote locations present many difficulties for their studyand monitoring. ... -
Interannual Variation of a 12,760 km Transequatorial Ionospheric Channel Availability and Its Dependence on Ionization
(1st International Electronic Conference on Atmospheric Sciences, 2016-07-15)The ionosphere provides a channel able for long-haul and Non-Line-Of-Sight (NLOS) communications. Nonetheless, the amount of ionization depends on the Sun activity, whose diurnal and seasonal cycles ... -
Physical Layer Definition for a Long-Haul HF Antarctica to Spain Radio Link
(Remote Sensing. 2016. Vol.8 No.5 (Maig), 2016-05)La Salle and the Observatori de l’Ebre (OE) have been involved in a remote sensing project in Antarctica for the last 11 years. The OE has been monitoring the geomagnetic activity for more than twenty ... -
Polarization diversity in a long-haul transequatorial HF link from Antarctica to Spain
(Radio Science. 2017. Vol.52 Nº.1 (Gener), 2017-01)This paper describes a set of experiments which examine the feasibility of applying polarization diversity to a 12,760 km ionospheric link from Livingston Island (62.6°S, 60.4°W), South Shetlands, to ... -
Vertical and oblique ionospheric soundings over a very long multihop HF radio link from polar to midlatitudes: Results and relationships
(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 ... -
Vertical and oblique ionospheric soundings performance comparison over the 12,760 km transequatorial HF link between Antarctica and Spain
(Radio Science. 2017. Vol.52, No.4 (Abril), 2017-03)This paper presents the second part of the study of the oblique sounding of a 12,760 km transequatorial ionospheric link between Livingston Island (Antarctica) and Cambrils in Spain. The study consists ...
