New IAG Publications | Geodesistโ€™s Handbook 2024 & IAG Travaux 2023โ€“2025

The IAG has released two flagship open-access references: the Geodesistโ€™s Handbook 2024 and the IAG Travaux Report 2023โ€“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.

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.
