The FAA has announced the completion of a nationwide infrastructure upgrade as part of the Next Generation Air Transportation System. Installation of the Automatic Dependent Surveillance-Broadcast radio network supports a satellite-based surveillance system that tracks aircraft with the help of GPS, providing greater positional accuracy. “The installation of this radio network clears the way for air traffic controllers to begin using ADS-B to separate equipped aircraft nationwide,” said FAA administrator Michael Huerta, adding, “It will also provide pilots flying aircraft equipped with the proper avionics with traffic information, weather data and other flight information.” About 100 air traffic facilities are using this system to separate traffic and the FAA expects all 230 to be using it by 2019.
