Safety Relevant Positioning Applications in Rail Traffic using the European Satellite System "Galileo" [PDF]

, 2006
Die Ortung im Eisenbahnverkehr hat eine hohe sicherheitstechnische Relevanz. Eine falsch detektierte Position eines Fahrzeugs kann zu einer erheblichen Gefährdung führen, da die ermittelte Ortsinformation für die Freigabe und das Wiederbesetzen von ...

Law and Infrastructure: Reliability, Automation Transition, and Irregularities of “U‐Space”

Regulation &Governance, EarlyView.
ABSTRACT The European Union (EU) is making regulatory efforts to allow for the safe integration of drones into civilian airspace through automated means. Commission Implementing Regulation (EU) 2021/664 concerning unmanned traffic management (a system referred to as “U‐Space”) furthers that commitment. Accordingly, drone operators must avail themselves

Glacier‐Atmosphere Interactions and Feedbacks in High‐Mountain Regions ‐ A Review

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Mountain glaciers are among the natural systems most vulnerable to climate change. However, their interactions with the atmosphere are complex and not fully understood. These interactions can trigger rapid adjustments and climate feedbacks that either amplify or attenuate atmospheric signals, influencing both glacier response and large‐scale ...

An enhanced pricing model for truck transportation: a case study in Swedish forestry

International Transactions in Operational Research, Volume 33, Issue 2, Page 775-797, March 2026.
Abstract Determining freight rates for heavy trucks involves a detailed analysis of multiple cost factors, including time, distance, fuel, and other operational costs, which collectively contribute to the overall compensation for transportation services. However, actual remuneration is based on more simplified agreements.

Polygonal tepee structures of Arabia

The Depositional Record, Volume 12, Issue 1, February 2026.
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

Contribution of SLR observations to precise orbit determination and geocenter motion estimation using Galileo and Sentinel-6A satellites as space ties

Geo-spatial Information Science
The GNSS and SLR observation capabilities of both the Galileo and Sentinel-6A satellites provide potential space ties, improving the accuracy of orbit and geocenter motion measurements. This study seeks to evaluate the influence of SLR data on the orbits

Applying Hpo Indices to Empirical Thermospheric Density Models During Geomagnetic Storms

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract Accurate atmospheric drag modeling is essential for precise orbit determination and prediction of Low Earth Orbit satellites. A key component is the thermospheric density, typically estimated using empirical models driven by geomagnetic activity indices such as the 3‐hr Kp or ap.

A novel mode of INS-aided BDS real-time high-rate and precise kinematic relative positioning between two moving platforms

Geo-spatial Information Science
For kinematic relative positioning users between two moving platforms, limited communication bandwidth and computation ability usually cannot support real-time transmission of high-rate (≥10 Hz) BeiDou Navigation Satellite System (BDS) data.
