Lost Without Geodesy

, , , , ,
What happens if geodesy disappears? Phones, planes, and warning systems would fail. Our cartoon “Lost Without Geodesy” shows how vital this invisible science is. Geodesy powers GNSS, enabling precise positioning, earthquake monitoring, sea level studies, and more. Without it, GNSS would drift and global systems would collapse.

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.
