GPS, or Global Positioning System, is a technology that uses satellites to determine the exact location of a device or person on the Earth's surface. GPS receivers pick up signals from multiple satellites to triangulate the user's position with high accuracy. This technology is widely used in navigation, tracking, mapping, and various other applications such as transportation, surveying, and disaster management. GPS has become an integral part of modern life, enabling us to easily find our way, track assets, and monitor movements in real-time.
