Satellite Positioning

Satellite positioning relies on a network of satellites orbiting the Earth that broadcast signals with their location and the precise time. Devices like GPS receivers pick up signals from multiple satellites and calculate their distance based on how long the signals take to arrive. By combining data from at least four satellites, the receiver determines its exact position in three dimensions—latitude, longitude, and altitude. This system enables accurate navigation and location services across the globe, essential for everything from smartphones to vehicle navigation and mapping applications.
