Orbiting trackers pinpoint your position with their accurate distance meters.
Getting lost on Earth is no longer a worry since the invention of the Global Positioning System (GPS). Once a military application, this powerful technology has now become an essential tool in our everyday life. A sophisticated system with tens of satellites, equipped with highly precise quantum clocks, was deployed in orbit to track our position with precise distance measurements. To build this technology, many advances in our understanding of the universe proved to be necessary, such as spacetime curvature, speed of light, and quantum phenomena.
How does general relativity play a crucial role in this technology?
