The Geocenter of the Earth Is Changing (And Why That Matters)

The video explains how GPS apps rely on a terrestrial reference frame (TRF) for accurate location services. Geodesy, the science of measuring Earth's shape and orientation, is crucial for understanding Earth's constant changes. NASA and international partners use measurement stations worldwide to monitor these changes. The geocenter, or Earth's center of mass, is vital for satellite orbits and is affected by natural events. Global collaboration is essential for comprehensive Earth measurement and data sharing.
