IERS | Relaunch of the Website www.iers.org

We are pleased to announce that, as of November 10, the IERS website has been relaunched and is now available in its updated form at www.iers.org. The main focus of this update was the modernization of the layout. The structure and the overall navigation have not changed significantly, ensuring that information may still be accessed in the familiar manner. In the course of the relaunch, we also took the opportunity to review and, where appropriate, update the content. We invite you to explore the new website and welcome any feedback or suggestions you may have.

Call for Abstracts – EGU26 Session G2.2 “New Technologies for GGOS”

The Global Geodetic Observing System (GGOS) invites contributions to Session G2.2 “New Technologies for the Global Geodetic Observing System (GGOS)” at the EGU General Assembly 2026 in Vienna. This session will highlight innovations and advances in geodetic observing systems for monitoring Earth’s geometry, gravity, and rotation. Topics include emerging technologies such as relativistic geodesy, quantum sensors, next-generation laser systems, LEO-based positioning, navigation and timing (PNT), and other forward-looking geodetic techniques. The session also welcomes contributions on general GGOS developments, new observatory concepts, and strategies to enhance the global geodetic infrastructure. Join us in shaping the future of geodesy and exploring how cutting-edge technology can strengthen GGOS’s role in observing and understanding our dynamic planet. Abstract Deadline: 15 January 2026, 13:00 CET
