Security
ADS-B Vulnerability Remains a Serious Concern

An article in AIN’s September issue addressed concerns that have been raised about the security of the ADS-B system, which is headed for widespread deployment around the world. ADS-B is designed to replace radar as the primary method for surveillance of airborne traffic. ADS-B can replace low-resolution radar detection of transponder-equipped aircraft with “automatic dependent surveillance-broadcast” or ADS-B signals, which broadcast speed, location and other information to properly equipped ground stations and other aircraft. ADS-B out-equipment, mandatory in the U.S. starting in 2020, transmits ADS-B information, while the more sophisticated ADS-B in equipment receives ADS-B information and makes it available to pilots.
