An Ambient Adaptive Global Navigation Satellite System Total Electron Content Predictive Model for Short-Term Rapid Geomagnetic Storm Events

Remote Sensing
Satellite navigation is an essential component of the national infrastructure. Space weather and ionospheric conditions are the prime sources of GNSS (global navigation satellite system) positioning, navigation, and timing (PNT) service disruptions and ...

Quantifying Changes in Water Loading in the U.S. Southwest via Comparison of GNSS, GRACE, and SWE Data Sets

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract We use geodetic data to show that hydrologically distinct sub‐regions in the Southwest United States act independently of one another. The limited number of Global Navigation Satellite System (GNSS) stations and resolution of Gravity Recovery and Climate Experiment (GRACE) make hydrological partitioning difficult to unravel, especially in the ...

Sediment addition at the saltmarsh–mangrove ecotone shifts species dominance with implications for restoration

Journal of Applied Ecology, Volume 63, Issue 2, February 2026.
Our results reveal that emerging ecological communities may tolerate and benefit from restoration similar to better studied temperate systems. However, we show that community composition in these habitats may shift and develop along different trajectories in response to restoration interventions, with implications for managers targeting specific post ...

Mind‐Muscle‐Environment Interactions: Psychophysiological Determinants of Optimal Pacing in Olympic Winter Endurance Sports

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT Pacing is a critical determinant of performance in Olympic endurance winter sports such as cross‐country skiing, biathlon, and speed skating. Although the physiological (“engine”) and psychological (“operator”) determinants of pacing have frequently been examined in isolation, growing evidence highlights the need for an integrated ...

Technology on Snow and Ice: Innovation, Monitoring, and Performance for the Olympic Winter Games Milano Cortina 2026

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 2, February 2026.
ABSTRACT Elite performance in Olympic winter sports depends on the interplay among the athlete, equipment, and the snow or ice. This naturally evolves with temperature, humidity, wind, preparation, and contact between the equipment and its surface. Together, these factors continuously rebalance the forces of gravity, aerodynamic drag, and friction ...

CELESTIAL NAVIGATION AS THE EMERGENCY GNSS BACKUP: ENHANCING NAVIGATIONAL RELIABILITY

Scientific Journal of Gdynia Maritime University
The development of Global Navigational Satellite Systems (GNSS) has revolutionised navigation on ships. GNSS, together with electronic chart display information system (ECDIS), has made navigation more accurate, efficient, and safer for sailors. However

A Multi‐Scale Approach to Assessing Positioning Accuracy in High‐Density Urban Environments of Hong Kong

Transactions in GIS, Volume 30, Issue 1, February 2026.
ABSTRACT This study examined GPS positioning accuracy in high‐density urban environments using Hong Kong as a representative case study. Through field measurements along 32 testing routes using three GPS devices, we evaluated GPS performance across diverse urban morphologies to assess associations between complex urban characteristics and positioning ...

Origin of Intense Plasma Depletions After Midnight Over the Korean Peninsula During the Geomagnetic Storm on 11 May 2024

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract A band of total electron content (TEC) depletions of about 5–15 TEC unit passed over the Korean Peninsula after midnight during the geomagnetic storm on 11 May 2024. This magnitude of TEC depletions has not been previously reported in the region.

Global Navigation Satellite Systems (GNSS) i fältförsök

, 2010
Huvudmålet med projektet var att finna metoder som effektiviserar fältförsöksutförandet. Projektdel 1 syftade till att undersöka om GNSS-baserad navigation kunde användas vid gränsning av försök, för att ersätta manuell gränsning. Målet var att få till stånd två i praktiken användbara system för GNSS-gränsning, samt att studera teknikens möjligheter ...
