Variations in Satellite Charge Drag Coefficient With Solar Cycle

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Ionospheric plasma interaction with charged satellite surfaces can lead to a substantial increase in orbital drag. In this context, natural events related to solar activity can have a detrimental effect on a satellite's lifespan and introduce uncertainty in orbital trajectory predictions.

Regional Medium‐Scale Traveling Ionospheric Disturbance Propagation Model Based on BDS GEO Satellites

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Accurate modeling of traveling ionospheric disturbances (TIDs) is essential for characterizing their spatiotemporal variations and mitigating their effects on Global Navigation Satellite System (GNSS) precise positioning. This study develops a regional medium‐scale TID (MSTID) propagation model using BeiDou geostationary orbit (GEO) total ...

Temporal variations of geoid heights over Kazakhstan from GRACE–FO data and their relation with hydrological changes in the Caspian Sea and seismic activity

open access: yesFrontiers in Earth Science
IntroductionWe quantify temporal variations of geoid heights (ΔN) across Kazakhstan during 2019–2024 using satellite gravimetry, and relate these changes to recent extreme hydrological and seismic events.MethodsMonthly ΔN fields were derived from GRACE ...

Global Ionospheric Slab Thickness Prediction Model Using XGBoost and Ensemble Learning

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract The ionospheric equivalent slab thickness is a key parameter for understanding the plasma distribution in the ionosphere, with direct relevance to satellite navigation, communication, and skywave over‐the‐horizon radar. However, traditional prediction methods often suffer from regional biases, limiting their global applicability.

Freshly Generated Super Sunrise Plasma Bubbles During the Geomagnetic Storm on November 5–6, 2023

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract During the geomagnetic storm on November 5–6, 2023, freshly generated super sunrise equatorial plasma bubbles (EPBs) and associated irregularities over the 80°–140°E sector were observed combining ground‐based and space observations from GNSS, ionosondes, HF Doppler records, and several satellite missions (COSMIC2, Swarm, and DMSP).

Evidence and Causes of an Unusual Super Plasma Bubble Occurrence During Weak Geomagnetic Conditions Over Europe

open access: yesSpace Weather, Volume 24, Issue 1, January 2026.
Abstract Using data from a cluster of ground‐based global navigation satellite system, we observed spatially extended enhanced ROTI over the European longitudes during a weak geomagnetic storm (Dst ≈ ${\approx} $ −50 nT) on 4 November 2023. The enhanced ROTI is extended over an extensive geographical latitudinal range of 46°N.
