A Review of Ionospheric Scintillation Models [PDF]

Surveys in Geophysics, 2015
This is a general review of the existing climatological models of ionospheric radio scintillation for high and equatorial latitudes. Trans-ionospheric communication of radio waves from transmitter to user is affected by the ionosphere which is highly variable and dynamic in both time and space. Scintillation is the term given to irregular amplitude and

Role of the magnetospheric and ionospheric currents in the generation of the equatorial scintillations during geomagnetic storms [PDF]

Annales Geophysicae, 2004
The equatorial ionosphere parameters, Kp, Dst, AU and AL indices characterized contribution of different magnetospheric and ionospheric currents to the H-component of geomagnetic field are examined to test the geomagnetic activity effect on the ...

Ionospheric Scintillation Prediction on S4 and ROTI Parameters Using Artificial Neural Network and Genetic Algorithm

Remote Sensing, 2021
Irregularities in electron density usually correlate with ionospheric plasma perturbations. These variations causing radio signal fluctuations, in response, generate ionospheric scintillations that frequently occur in low-latitude regions.

Machine learning approach for prediction of total electron content and classification of ionospheric scintillations over Visakhapatnam region

AIP Advances, 2023
Ionospheric scintillations, which are due to ionospheric plasma density anomalies, negatively impact trans-ionospheric signals and the positioning accuracy of the global navigation satellite system (GNSS).

Influence of geomagnetic disturbances on scintillations of GLONASS and GPS signals as observed on the Kola Peninsula

Solar-Terrestrial Physics, 2023
We have compared effects of geomagnetic disturbances during magnetic storms of various types (CME and CIR) and during an isolated substorm on scintillations of GLONASS and GPS signals, using a Septentrio PolaRx5 receiver installed in Apatity (Murmansk ...

Ionospheric irregularities and scintillations: a direct comparison of in situ density observations with ground-based L-band receivers

Earth, Planets and Space, 2020
Ionospheric irregularities can affect satellite communication and navigation by causing scintillations of radio signals. The scintillations are routinely measured using ground-based networks of receivers.
