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 ...

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 ...

Ionospheric scintillations associated with equatorial plasma bubbles in Southeast Asia during the ascending and maximum phases of Solar Cycle 25

Earth, Planets and Space
This paper presents ionospheric scintillation observations in Southeast Asia during the ascending and maximum phases of Solar Cycle 25 (2020–2025). Ionospheric scintillation has been widely used to investigate equatorial plasma bubbles (EPBs) for several

Interferometric observation of Cygnus-А discrete radiosource scintillations at Irkutsk Incoherent Scatter radar

Solar-Terrestrial Physics, 2016
We propose a new method for analyzing data from the Irkutsk Incoherent Scatter Radar. The method allows us to accomplish interferometric observation of discrete cosmic radio source characteristics.

Characteristics of VHF scintillations in the equatorial anomaly crest region in India [PDF]

Annales Geophysicae, 1995
The characteristics of ionospheric scintillations at Rajkot in the equatorial anomaly crest region in India are described for the years 1987–1991 by monitoring the 244-MHz transmission from the satellite FLEETSAT.

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.

The ionospheric scintillation phenomenon

, 2022
The SAGAIE network was deployed in West-Africa in 2013 to assess the feasibility of an equatorial for ASECNA SBAS by studying ionospheric scintillation. This study of the network’s measurements, taken between 2013 and 2016, analyzes the characteristics of the scintillation recorded by five receivers that cover Sub-Saharan West-Africa.

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.
