Investigation on the Impact of Tropospheric Delay on GPS Height Variation near the Equator
, 2009 One of the major problems currently facing satellite-based positioning is the atmospheric refraction of the GPS signal caused by the troposphere. The tropospheric effect is much more pronounced at the equatorial region due to its hot and wet conditions ...

The Impact of the 2024 Mother's Day Storm on Aircraft Surveillance Across Europe
Space Weather, Volume 23, Issue 12, December 2025.Abstract The Mother's day storm from 10–13 May 2024 is one of the most extreme space weather events recorded in recent decades and triggered a strong ionospheric response with various impacts on communication and navigation systems. In this study the impact on the aviation sector, and more specifically air traffic management, is investigated with ...
