New IAG Publications | Geodesist’s Handbook 2024 & IAG Travaux 2023–2025
Com1, Com2, Com3, Com4, ECS, GGOS, IAG, ICCC, ICCM, ICCT, Project QuGe, Services, 🏛️ Organisation NewsThe IAG has released two flagship open-access references: the Geodesist’s Handbook 2024 and the IAG Travaux Report 2023–2025. The Handbook presents IAG statutes, structure, officers, and planned scientific activities, while the Travaux documents scientific and organizational progress across all IAG components. Both volumes provide DOIs for the full work and for each chapter, supporting precise citation and strengthening the international visibility of IAG activities.

From Struve to Space: 11th Nordic Geodetic Commission Summer School held in Estonia 2025
Com4, ECS, IAG, 📅 Event UpdateThe 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.

Satellite Laser Ranging – How SLR Powers Geodesy
Com1, Com4, ECS, GGOS, IAG, ILRS, 🌍 Geodesy NewsDiscover 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.

Geodesy Virtual School 2025 – Summary
Com1, Com2, ECS, GGOS, Other, 📅 Event UpdateThe 2025 Geodesy Virtual School focused on reference frames and Earth system monitoring, held in five free online sessions coordinated from Argentina with support from SIRGAS, IAG, IUGG, and others. It featured 37 instructors and global participation, especially from the Americas. All lectures, in English or Spanish with subtitles, are available online, promoting inclusive, high-quality geodetic training worldwide.

Lost Without Geodesy
Com4, ECS, GGOS, IAG, IGS, 🌍 Geodesy NewsWhat 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.

IAG Scientific Assembly 2025 – Third Circular
ECS, IAG, 📅 Event UpdateThe IAG Scientific Assembly will take place in Rimini, Italy, on September 1–5, 2025. Abstract selection is complete, with 300 oral and 388 poster presentations scheduled. Early Career Scientists are encouraged to apply for IAG Travel Grants by July 31. Social events include an ECS Dinner and a Women in Geodesy Breakfast.
