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…

A new atomic clock in space could help us measure elevations on Earth
What if we could measure height differences on Earth to the centimeter from space? ESA’s ACES mission on the ISS links ultra-precise atomic clocks in orbit with those on Earth — enabling more accurate global elevation data. This could transform geodesy and help refine height reference systems worldwide.
