Modeling the GNSS Rural Radio Channel: Wave Propagation Effects caused by Trees and Alleys [PDF]
, 2009 Among the various physical influencing factors with the potential to degrade the overall performance of a global navigation satellite system (GNSS), the behavior of the radio wave propagation channel occupies doubtlessly a central role.

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The Mw 7.7 Myanmar earthquake on 28 March 2025 ruptured ∼480 km of the Sagaing Fault. Its fault slip distribution remains poorly constrained by three‐dimensional surface displacement data due to sparse GNSS‐coverage near the fault. Satellite‐based synthetic aperture radars capture meters of right‐lateral displacements but isolating vertical ...

Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.

Ecology and Evolution, Volume 16, Issue 10, October 2026.Drone‐based measurements of free‐ranging aquatic wildlife are inevitably affected by posture variations, yet this issue has remained largely unaddressed. We developed a drone‐based method of estimating body measurements of dugongs using dual drones (positioned vertically and obliquely relative to the animal) whilst considering body posture.

Multi‐source DOA estimation based on multi‐UAV collaboration in complex GNSS spoofing environments
IET Radar, Sonar & NavigationUnmanned Aerial Vehicles (UAVs) are widely used in both military and civilian sectors due to their maneuverability and versatility. However, UAVs rely on the Global Navigation Satellite System (GNSS) for real‐time accurate navigation and are therefore ...

A Data‐Driven Review of Geoscience Research Evolution Using SciBERT‐Based Topic and Network Analysis
Geoscience Data Journal, Volume 13, Issue 4, October 2026.This review synthesises the evolution of global geoscience research from 2004 to 2023 using large‐scale bibliometric evidence. By combining keyword co‐occurrence network analysis with SciBERT‐based topic modelling, it identifies major paradigm transitions from geology‐centred research to climate‐focused studies and recent data‐ and AI‐driven ...

Dataset of Coastline Positions for Sandy Beaches of England and Wales Derived Using Remote Sensing
Geoscience Data Journal, Volume 13, Issue 4, October 2026.Two decades (1999–2020) of annual coastline position dataset were generated using COASTSAT toolkit for sandy beaches of England and Wales. The dataset consists of annual coastline position coordinates in the format of GeoJSON and Tabular files. ABSTRACT This article presents a dataset of coastline positions, comprising annual sandy coastline detections
