GPS stands for Global Positioning System. It is a satellite-based navigation system that allows users to determine their exact location (latitude and longitude) anywhere on Earth using a GPS receiver. Developed and maintained by the U.S. Department of Defense, GPS was originally designed for military navigation but has since been made available for civilian use. The system consists of a constellation of satellites orbiting the Earth, ground control stations, and the GPS receivers used by individuals and organizations. GPS technology is widely used in various applications, including mapping, navigation for vehicles, and timing services for financial transactions.
