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

  • Due to different zero points for elevation, a bridge across the Rhine River experienced a 54-centimeter misalignment between German and Swiss sides.
  • To standardize elevation measurement globally, the International Height Reference Frame (IHRF) was adopted in 2015.
  • The most accurate clock in space, the Atomic Clock Ensemble in Space (ACES), was launched to enhance precision.
  • ACES, consisting of cesium and hydrogen atomic clocks, offers unparalleled precision and stability.
  • Geodesists can use ACES to perform tests of fundamental physics and make more precise gravitational measurements.
  • A synchronized clock network from space will aid in establishing a more accurate zero point for elevation measurements worldwide.
  • The current geoid model lacks precision, particularly in Africa and South America, due to limited surveys.
  • Proposed worldwide clock network aims to map Earth's gravitational field more accurately, leading to a more precise geoid model.
  • Improving the geoid's precision can aid in infrastructure projects and resolving disputes, like the Mount Everest height discrepancy.
  • Development of the clock network is a lengthy process requiring dedicated efforts from scientists and engineers.
