The Global Positioning System (GPS), a constellation of 31 satellites orbiting Earth, has revolutionized the way we navigate, communicate, and conduct business. Developed by the United States Department of Defense, GPS provides precise location and timing information to users worldwide. Employing a network of ground stations, control centers, and satellites, GPS operates on the principle of trilateration, where receivers on Earth measure the time it takes for signals to travel from multiple satellites, allowing them to calculate their position accurately. This technology underpins various applications, from military operations to commercial navigation systems, making GPS an indispensable tool in modern society.
