The Visibility Challenge of Geodesy

Geodesy quietly underpins our modern world - from GNSS navigation to climate monitoring and digital twins. The new article “The Visibility Challenge of Geodesy” in the GIM International Magazine (Issue 4 2025) explores the global infrastructure behind geodesy and highlights initiatives to make it more visible and accessible to surveyors, geomatics professionals, and the wider geospatial community.

Obituary of Bernard Chovitz

Bernard Chovitz († April 25, 2025) was a pioneering geodesist and NOAA official. He advanced Geodesy from 2D to modern 3D/4D models, contributing to gravity field analysis, satellite data, and reference systems. His work, alongside geodetic giants, profoundly shaped the field. The International Association of Geodesy honors his legacy.

Highlights from 1st GGOS IberAtlantic Summer School

The Yebes Observatory hosted GGOS IberAtlantic’s inaugural Summer School on space geodesy for early-career researchers from Spain and Portugal. Over five days, participants explored GNSS, VLBI, SLR, and gravimetry through theoretical and hands-on sessions, while cultural activities fostered collaboration. The event successfully strengthened geodetic skills, inspired scientific vocations, and built networks across the Ibero-Atlantic region.

Satellite Laser Ranging – How SLR Powers Geodesy

Discover Satellite Laser Ranging (SLR) – lasers from ground stations measure satellite and Moon positions with millimeter precision. SLR supports the Terrestrial Reference Frame, tracks Earth rotation, tectonic motion, improves gravity and sea level models, and tests relativity. Explore the science behind these precision measurements in our Geodesy Cartoon.
