On 15th and 16th of October 2026 the ICGEM Workshop brought together expert users and the project team to discuss the future of ICGEM.
Presentation from IAG Rimini 2025
Recent activities and its contribution to the gravity field related products.
We redesigned the website
ICGEM keeps advancing: our website is now powered by the Bootstrap framework. Stay tuned for updates and a responsive design. We welcome your feedback!
User Survey results
The Results of the ICGEM User Survey are now available. Thank you to everyone who participated and shared their valuable insights.
