Navigation Services
Global Navigation Satellite Systems The FAA Global Navigation Satellite System (GNSS) Program Office provides satellite (GPS) based positioning, navigation, and timing (PNT) services in the United States to enable performance-based (RNP/RNAV) operations for all phases of flight from en route, terminal, approach, and surface navigation. PNT services are an essential enabler required to overcome the deficiencies in today's air traffic infrastructure and support implementation of the Next Generation Air Transportation (NEXTGEN) system for the United States' National Airspace System (NAS). The FAA's plan to provide PNT services requires implementation of two GPS augmentation systems, the Wide Area Augmentation System (WAAS) and the Local Area Augmentation System (LAAS). Both systems improve the accuracy, availability, and integrity needed to support continuous all-weather use of GPS as a primary means of navigation and automated dependent surveillance (ADS-B) within the NAS. The GNSS Team, along with other FAA organizations and numerous governmental and non-governmental agencies, are all supporting a smooth transition to satellite navigation. Visit us and see what’s new.
