A new atomic clock in space could help us measure elevations on Earth
🌍 Geodesy News, Com1, Com2, GGOS, IGFS, ISG, Project QuGeWhat 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.
