GPS (Global Positioning System) technology functions for navigation by using a network of satellites orbiting the Earth. A GPS receiver calculates its position by triangulating signals from at least four satellites. Each satellite sends precise time-stamped signals, allowing the receiver to determine its distance from each satellite based on the time taken for the signal to travel. This information is then processed to provide accurate location coordinates, enabling real-time tracking and navigation directions. GPS is widely used in vehicles, smartphones, and outdoor activities.
