How Does it Work? - GPS

The video explains how GPS navigation works, using Ava's journey to an amusement park as an example. It describes the role of GPS satellites, which orbit the Earth and contain atomic clocks for precise timekeeping. Ava's phone communicates with these satellites to calculate her exact location using the speed of light and trilateration. The GPS app then provides turn-by-turn directions. The video highlights the incredible precision of GPS technology, which can pinpoint locations within a few yards anywhere on Earth.
