GPS systems, or Global Positioning Systems, are satellite-based navigation tools that help users determine their exact location anywhere on Earth. They work by receiving signals from a network of satellites orbiting the planet, which allows devices to calculate their position using triangulation. This technology is widely used in various applications, including driving directions, outdoor activities, and mapping services. In addition to navigation, GPS systems can also provide information about speed, distance traveled, and estimated arrival times. Many smartphones and vehicles are equipped with GPS capabilities, making it easier for people to find their way and explore new places efficiently.
