No one likes to be lost. The Global Positioning System (GPS) is the modern successor to maps, start positions and landmarks, all of which help us find our way on land or sea. Developed by the U.S. military, the GPS is actually a constellation of 27 Earth-orbiting satellites (24 in operation and three extras in case one fails). Take this quiz to learn more about using the GPS.
