ADS-B Transmitter Maps

As demand for our nation's airspace grows, NextGen improvements are helping to guide and track aircraft more precisely on more direct routes. The shift to smarter technologies is making air travel safer, more convenient, and more environmentally friendly.

ADS-B (Automatic Dependent Surveillance-Broadcast) is a foundational NextGen technology that uses the GPS satellite system to track aircraft in real time. That same satellite precision has now been adapted to airport vehicles, making runways safer and more efficient.

When airport vehicles are equipped with ADS-B, they can be tracked in real time along with aircraft at the airport. Displays give pilots, controllers, vehicle operators, and airport and airline managers a better view of airfield operations. This capability has many uses and can be especially helpful at night or during low-visibility weather.

Vehicle ADS-B is not mandated but will likely become widespread as airports realize its benefits. Several major airports have already implemented vehicle ADS-B.

These maps show the area on the airport surface that vehicle ADS-B is enabled or disabled. The yellow coloring is the enabled areas and the red coloring is the disabled area.
