The FAA has completed an infrastructure update to allow air traffic controllers to track aircraft with greater accuracy. Air traffic controllers across the US will use the Automatic Dependent Surveillance-Broadcast (ADS-B) radio network, which supports a satellite-based surveillance system to track aircraft with GPS. The network is more accurate than the current radar system. Anthony Foxx, US transportation secretary, said: “This upgrade is an important step in laying the foundation for the NextGen system, which provides controllers a much more precise view of the airspace, gives pilots much more awareness and information, and as a result strengthens the safety and efficiency of our system.” Pilots will also benefit from the system, which provides traffic information and weather data to the cockpit. The FAA expects all aircraft operating in controlled airspace to be equipped with ADS-B avionics by 2020.
