An array of ring lasers provides the first continuous measurement of Earth’s motion from a single location.
Earth’s rotational velocity and axis orientation experience constant fluctuations caused by changes in the planet’s interior, in the oceans, and in the atmosphere. Researchers now report the first continuous measurements of these miniscule fluctuations, using an arrangement of four laser gyroscopes buried underground in Germany. Data from this new facility will be important for maintaining up-to-the-moment accuracy for GPS-based navigation.
