FAA´s Satellite Program Office-satellite navigation program and status

No single technology has more broad reaching potential for worldwide civil aviation than the future applications of satellite technology. These applications would represent the greatest opportunity to enhance aviation system capacity, efficiency, and safety since the introduction of radio-based navigation more than fifty years ago. The Federal Aviation Administration (FAA), who is responsible for the management and control of all civil aviation in the U.S. has responded to this potential through initiation of a comprehensive satellite program involving government, industry, and users to expedite research, development, and field implementation of satellite-based navigation services
