ADS-B is being used now to control air traffic across the nation. Its real-time precision and new tools help controllers manage traffic for improved safety and capacity.
With ADS-B, ground stations are small and easily maintained, and can be placed in areas where radar was never possible. The Gulf of Mexico, for example, now has complete coverage with ADS-B installations on oil platforms and along the coast.
ADS-B aircraft tracking is near instantaneous and transmitted to both pilots and controllers for shared situational awareness.
ADS-B is also transmitted aircraft-to-aircraft, enabling air traffic control advances that will allow aircraft to maintain precise intervals in time and space.
