Analysis of Ionospheric Scintillation Characteristics in Sub-Antarctica Region with GNSS Data at Macquarie Island [PDF]

Sensors, 2017
Ionospheric scintillation has a great impact on radio propagation and electronic system performance, thus is extensively studied currently. The influence of scintillation on Global Navigation Satellite System (GNSS) is particularly evident, making GNSS ...

Prediction of Ionospheric Scintillation with ConvGRU Networks Using GNSS Ground-Based Data across South America [PDF]

Remote Sensing
This study investigates the relationship between geomagnetic activities and ionospheric scintillations, focusing on how solar and geomagnetic parameters influence ionospheric disturbances across varying time frames and latitudes.

Towards the possibility to combine LOFAR and GNSS measurements to sense ionospheric irregularities

Journal of Space Weather and Space Climate, 2023
Inhomogeneities within the ionospheric plasma density affect trans-ionospheric radio signals, causing radio wave scintillation in the amplitude and phase of the signals.

Climatology of GPS phase scintillation and HF radar backscatter for the high-latitude ionosphere under solar minimum conditions [PDF]

Annales Geophysicae, 2011
Maps of GPS phase scintillation at high latitudes have been constructed after the first two years of operation of the Canadian High Arctic Ionospheric Network (CHAIN) during the 2008–2009 solar minimum.

Climatology of GPS ionospheric scintillations over high and mid-latitude European regions [PDF]

Annales Geophysicae, 2009
We analyze data of ionospheric scintillation in the geographic latitudinal range 44°–88° N during the period of October, November and December 2003 as a first step to develop a "scintillation climatology" over Northern Europe.
