The Global Positioning System (GPS) is a satellite-based navigation system that provides geolocation and time information to a GPS receiver anywhere on Earth. Developed by the U.S. Department of Defense, GPS uses a network of around 30 satellites orbiting the Earth, transmitting signals that allow users to determine their exact position, speed, and direction. GPS technology is used in many applications, from navigation in cars, airplanes, and ships to location-based services in smartphones. It has revolutionized industries like transportation, military operations, and outdoor activities like hiking, offering precise and reliable positioning data.
