From Struve to Space: 11th Nordic Geodetic Commission Summer School held in Estonia 2025
The Nordic Geodetic Commission’s 11th Summer School "From Struve to Space" gathered 61 participants from 13 countries in Tartu, Estonia (Aug 25–29, 2025). Hosted for the first time on the Baltic shore, the event blended history and innovation — exploring GNSS, machine learning, and geodesy’s future. A collegial, inspiring setting connected young researchers with Struve’s scientific legacy.

IAG Honors Outstanding Contributions in Geodesy: Awardees of 2023 and 2024
The International Association of Geodesy (IAG) has honored four outstanding scientists with its Young Author’s and Best Reviewer’s Awards for 2023 and 2024. The recipients are Dr. Safoora Zaminpardaz, Dr. Justyna Śliwińska-Bronowicz, Dr. Bailing Li, and Dr. Judit Benedek. These awards recognize excellence in scientific research and dedicated service to the geodetic community worldwide.

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.

Lost Without Geodesy
What happens if geodesy disappears? Phones, planes, and warning systems would fail. Our cartoon “Lost Without Geodesy” shows how vital this invisible science is. Geodesy powers GNSS, enabling precise positioning, earthquake monitoring, sea level studies, and more. Without it, GNSS would drift and global systems would collapse.

Welcome to the New IAG Website
We are excited to announce the official launch of the new IAG website geodesy.science. This launch marks a major milestone for the IAG and reflects our ambition to make geodesy more visible, accessible, and connected — both within the scientific…
