Global Positioning Systems, more commonly known as GPS, are electronic navigational systems based on satellite technology. They are comprised of 24 satellites that the U.S. Department of Defense placed in orbit, originally for military operations. The system was made available for civilian use in the 1980's. The popularity of Global Positioning Systems has been progressively rising since that time.
