A Safer and More Efficient Airspace: Automatic Dependent Surveillance-Broadcast (PDF)

Document

About This Document

The FAA's Next Generation Transportation System—NextGen—is transforming how air traffic controllers and pilots see our national airspace. By 2020, NextGen will make America's skies even safer and more efficient by transitioning from radar technology to a far more precise global satellite network. The backbone of this evolution is a technology called Automatic Dependent Surveillance-Broadcast (ADS-B), which U.S. DOT Volpe Center has helped develop and deploy for more than a decade.
