The Federal Aviation Administration (FAA) is transitioning from a system of ground-based navigation aids to one based upon a satellite-based Global Positioning System (GPS). Radar and other ground-based navaids limit the amount of airspace available and can increase travel distance, since aircraft must follow one navigational fix to another. Under GPS, several sequenced satellites orbiting the earth each transit an omnidirectional signal that reaches a receiver on the aircraft, which with precise timing information calculates a radius of distance from each satellite. The intersection of at least three spherical surfaces allows for the automated calculation of the aircraft's position. This process provides highly accurate information for en route navigation. GPS is already being used for navigation in oceanic and en route airspace.
In order to enhance the accuracy and reliability of GPS so that it can be used as a primary means of navigation and nonprecision approaches, the FAA has......
