Lincoln Lab team wins aero-astro award

The Robert J. Collier Trophy, awarded annually for significant achievements in aeronautics or astronautics in America, has been awarded to the Automatic Dependent Surveillance-Broadcast (ADS-B) public and private-sector team, which includes MIT Lincoln Laboratory.
 
ADS-B is a system in which each aircraft broadcasts its aircraft-determined position, intent and status information on the order of once each second. This broadcast position information can be received by other aircraft and by ground stations, providing robust air-to-ground and air-to-air surveillance. 
 
Lincoln Laboratory played a critical role in the conception, development and testing of ADS-B, and continues to support the Federal Aviation Administration's national implementation program. In 1992, Lincoln Laboratory proposed to the FAA the use of an expanded Mode-S squitter for the transmission of aircraft-derived position. This concept has evolved into the current ADS-B that allows aircraft to broadcast and receive ADS-B information using existing transponder equipment. It has been adopted worldwide as the commercial fleet's standard for ADS-B implementation.
