Global morphology of ionospheric scintillations

Proceedings of the IEEE, 1982
Starting with post World War II studies of fading of radio star sources and continuing with fading of satellite signals of Sputnik, vast quantities of data have built up on the effect of ionospheric irregularities on signals from beyond the F layer. The review attempts to organize the available amplitude and phase scintillation data into equatorial ...

Dynamic Evolution of a Storm‐Time “Super‐EPB” Event Over China on the Magnetically Disturbed Night of 01 December 2023

Space Weather, Volume 24, Issue 10, October 2026.
Abstract This paper investigates the dynamic evolution of a storm‐time “Super‐EPB” event over China on 1 December 2023 (Kp ≤ 7, SYM/H ≥ −130 nT) using multi‐instrument observations. Occurring near sunset as the IMF‐Bz abruptly turned southward, with auroral extension to midlatitudes, the “Super‐EPB” extended to 40°N with an apex height of ∼2,460 km ...

Coupled Thermosphere–Ionosphere Dynamics During the 17 January 2013 Storm: GITM–TIDAS Comparison With Millstone Hill ISR Measurements

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This article analyzes a weak geomagnetic storm on January 17–18, 2013, using a first‐principles model (Global Ionosphere Thermosphere Model (GITM) with an empirical assimilative ionospheric model (TIDAS), evaluated against observations in the form of Millstone Hill (MH) incoherent scatter radar (ISR) altitude profiles and global navigation ...

Ionospheric F‐Layer Scintillation Variabilities Over the American Sector During Sudden Stratospheric Warming Events

Space Weather, 2021
The present study investigates the ionospheric F‐layer scintillation responses in the American sector (90°W–0°, ±50° dip latitude) during the Northern Hemisphere winter sudden stratospheric warming events of 2007–2008, 2008–2009, 2009–2010, and 2012–2013.

On the Mitigation of Ionospheric Scintillation in Advanced GNSS Receivers [PDF]

IEEE Transactions on Aerospace and Electronic Systems, 2018
Ionospheric scintillation is one of the major threats and most challenging propagation scenarios affecting Global Navigation Satellite Systems (GNSS) and related applications. The fact that this phenomenon causes severe degradations only in equatorial and high latitude regions has led to very few contributions dealing with the fundamental scintillation

Characterization of High‐Frequency GNSS Total Electron Content Variations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Global Navigation Satellite System (GNSS)–derived Total Electron Content (TEC) is widely used to investigate ionospheric variability, but has primarily been applied to low‐frequency fluctuations. Here we present a long‐term statistical characterization of high‐frequency (30–500 mHz) TEC variations using multi‐constellation GNSS data from 11 ...

Development of an Automatic Detection System for Satellite Surface Charging Using DMSP Observation Data and Investigation of the Surrounding Plasma Environment

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Electrostatic discharge and potential differences from surface charging during satellite operations can cause serious damage and control malfunctions. Detecting and preventing such charging events is therefore critical for safe and reliable spacecraft servicing.

Variation of Global Ionospheric Scintillation and Its Effect on GPS Kinematic PPP‐AR Performance During Geomagnetic Storms in Solar Cycle 25: A Statistical Analysis

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Enhanced small‐scale ionospheric irregularities during geomagnetic storms can disturb Global Navigation Satellite System (GNSS) carrier‐phase tracking and are associated with reduced stability of ambiguity‐fixed precise point positioning (PPP‐AR), but their impact on kinematic positioning remains insufficiently quantified.
