ESA atomic clock satellite

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.
