GPS (Global Positioning System) is a satellite-based navigation system developed and operated by the United States government that allows users to determine their exact location, speed, and time anywhere on Earth. It consists of a constellation of at least 24 satellites orbiting the planet, transmitting signals that are received by GPS-enabled devices such as smartphones, cars, and navigation systems. By calculating the time it takes for signals from multiple satellites to reach the device, GPS determines the user’s precise coordinates. Widely used for mapping, navigation, tracking, and location-based services, GPS operates independently but can be enhanced by other systems like GLONASS, Galileo, or BeiDou for improved accuracy.
