Scintillation modeling

, 2020
In this chapter, some scintillation models are described, taking into account of the dynamical nature of the Earth's ionosphere and its “complexity.” After a short description of the problem, a detailed explanation is provided about the propagation model

Phase gradient screen approach in modeling of ionospheric scintillation [PDF]

, 2023
Multiple studies of scintillation events have shown that in certain situations the intense phase fluctuations of trans-ionospheric radio signals are associated with the scattering on strong electron density gradients. However, a theoretical understanding

AI-Driven Modeling of the S4 Index for UHF Satellite Communication

IEEE Access
Ionospheric scintillation significantly affects satellite communication links, particularly in low-latitude regions such as Brazil. However, the lack of observational S4 data in the UHF band, mainly available from Global Navigation Satellite System (GNSS)

GNSS station characterisation for ionospheric scintillation applications

, 2013
Ionospheric scintillations are fluctuations in the phase and amplitude of the signals from GNSS (Global Navigation Satellite Systems) occurring when they cross regions of electron density irregularities in the ionosphere.

An Alternative Approach for Pseudorange Variance Estimation Under Scintillation Environments Using Markov‐Rao‐Blackwellized Particle Filtering

IET Radar, Sonar & Navigation
Ionospheric scintillations, arising from variations in phase/amplitude of radio signals traversing the ionosphere, pose significant challenges to Global Navigation Satellite System (GNSS) positioning, particularly in low‐latitude regions.
