Observations of GPS ionospheric scintillations over Wuhan during geomagnetic storms [PDF]
Annales Geophysicae, 2006 During the two geomagnetic storms which occurred on 1 October 2002 and 22 January 2004, the strong ionospheric scintillations of the GPS L1 band were observed at Wuhan station (30.6° N, 114.4° E, 45.8° Dip), which is ...

Climatology and modeling of ionospheric scintillations and irregularity zonal drifts at the equatorial anomaly crest region [PDF]
Annales Geophysicae, 2017 In this study the climatology of ionospheric scintillations and the zonal drift velocities of scintillation-producing irregularities are depicted for a station located under the southern crest of the equatorial ionization anomaly.

High latitude ionospheric scintillations
Canadian Journal of Physics, 1984 The statistical characteristics of ionospheric irregularities are often described by specifying one or two of the statistical parameters of the scintillations that the irregularities produce in satellite radio signals. The most commonly used parameter for this purpose is the spectral index (slope of the power spectral density function on a log–log ...

RADIO STAR SCINTILLATIONS AND THE IONOSPHERE
Canadian Journal of Physics, 1955 The observed intensity at the surface of the earth of radiation at a frequency of 50 Mc./s. from a radio star has been studied. A relationship is shown to exist between the fluctuations, or scintillations, in this observed radiation intensity and the angle of its incidence on the 400 km. level of the earth's ionosphere.

Modeling of ionospheric scintillation [PDF]
Journal of Space Weather and Space Climate, 2022 A signal, such as from a GNSS satellite or microwave sounding system, propagating in the randomly inhomogeneous ionosphere, experiences chaotic modulations of its amplitude and phase. This effect is known as scintillation. This article reviews basic theoretical concepts and simulation strategies for modeling the scintillation phenomenon. We focused our

Ionospheric scintillations studies using Spire and COSMIC-2 radio occultation and GOLD satellite data [PDF]
, 2023 Low-earth orbits (LEO) satellites have been harnessing the concept of GNSS radio occultation (RO) for several atmospheric applications. With the advent of CubeSat technology, many space companies are now extending the GNSS-RO for ionospheric and space ...

Geodesy and Geodynamics, 2019 The amplitude and phase of L-band satellite signals are fluctuated randomly due to small scale electron density irregularity structures in the ionosphere which result in fleeting variations, known as ‘ionospheric scintillations’.

A different approach to the analysis of GPS scintillation data
Annals of Geophysics, 2002 Amplitude scintillation data from GPS were analyzed. The objective is to estimate the impact of ionospheric scintillations at Satellite Based Augmentation Systems Ranging and Integrity Monitoring Station (SBAS RIMS) level and at GPS user level.

Broadband meter‐wavelength observations of ionospheric scintillation [PDF]
Journal of Geophysical Research: Space Physics, 2014 Abstract Intensity scintillations of cosmic radio sources are used to study astrophysical plasmas like the ionosphere, the solar wind, and the interstellar medium. Normally, these observations are relatively narrow band.
