Physical Layer Definition for a Long-Haul HF Antarctica to Spain Radio Link
(MDPI, 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 ...
Vertical and oblique ionospheric soundings performance comparison over the 12,760 km transequatorial HF link between Antarctica and Spain
(Wiley, 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 ...
Narrowband and Wideband Channel Sounding of an Antarctica to Spain Ionospheric Radio Link
(MDPI, 2015-09)
La Salle and Ebro Observatory have been involved in remote sensing projects in Antarctica for the last 11 years (approximately one solar cycle). The Ebro Observatory has been monitoring and analyzing ...
Remote Geophysical Observatory in Antarctica with HF data transmission: a Review
(MDPI, 2014-07)
The geophysical observatory in the Antarctic Spanish Station Juan Carlos I (ASJI) in Livingston Island has been monitoring the magnetic field in the Antarctic region for more than fifteen years. In 2004, ...
Vertical and Oblique ionospheric soundings over the long haul HF link between Antarctica and Spain
(Wiley, 2015-09)
This paper presents a comparative study between the oblique sounding results, theInternational Telecommunication Union Rec533 HF prediction model, and the vertical sounding results of atransequatorial ...
Variation of Ionospheric Narrowband and Wideband Performance for a 12,760 km Transequatorial Link and Its Dependence on Solar and Ionospheric Activity
(MDPI, 2020-08)
The ionosphere provides a channel that is able to propagate electromagnetic waves for long-haul communications, allowing Non-Line-Of-Sight (NLOS) radio communications in the high-frequency band (HF). ...
Polarization diversity in a long-haul transequatorial HF link from Antarctica to Spain
(Wiley, 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 ...
Ionospheric Narrowband and Wideband HF Soundings for Communications Purposes: A Review
(MDPI, 2020-04)
High Frequency (HF) communications through ionospheric reflection is a widely usedtechnique specifically for maritime, aeronautical, and emergency services communication withremote areas due ...
Design and Validation of Probes and Sensors for the Characterization of Magneto-Ionic Radio Wave Propagation on Near Vertical Incidence Skywave Paths
(MDPI, 2019-06)
This article describes the design and validation of deployable low-power probes and sensors to investigate the influence of the ionosphere and the Earth’s magnetic field on radio wave propagation below ...
Radio communication via Near Vertical Incidence Skywave propagation: an overview
(Springer, 2017-02)
Near Vertical Incidence Skywave (NVIS) propagation can be used for radio communication in a large area (200 km radius) without any intermediate man-made infrastructure. It is therefore especially suited ...
