GPS satellites
Space-based positioning beacons
GPS satellites are spacecraft orbiting Earth that transmit signals enabling receivers on the ground to determine their precise location.
The system requires signals from multiple satellites to triangulate position through timing differences.
Originally developed by the U.S. military, GPS satellites now support civilian navigation in phones, cars, and aircraft: The GPS satellites overhead gave us our exact coordinates.
