ESA atomic clock satellite

A new atomic clock in space could help us measure elevations on Earth

🌍 Geodesy News, Com1, Com2, GGOS, IGFS, ISG, Project QuGe
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.
