The Global Positioning System is the responsibility of the Joint Program Office (JPO), a component of the Space and Missile Center at El Segundo, California. In 1973, the JPO was directed by the U.S. Department of Defense (DoD) to establish, develop, test, acquire, and deploy a spaceborne positioning system. The present Navigation System with Timing and Ranging (NAVSTAR) Global Positioning System (GPS) is the result of this initial directive.
