Conceptual of the ADS-B system, illustrating radio links between aircraft, ground station and satellite. Automatic Dependent Surveillance–Broadcast (ADS-B) is an aviation surveillance technology and form of electronic conspicuity in which an aircraft determines its position via satellite navigation or other sensors and periodically broadcasts its position and other related data, enabling it ...
In 2009 the ICAO published an "extended" form of Mode S with more message formats to use with ADS-B; [11] it was further refined in 2012. [12] Countries implementing ADS-B can require the use of either the extended squitter mode of a suitably-equipped Mode S transponder, or the UAT transponder on 978 MHz.
ICAO: Non-discrete mode A code reserved use in mode S radar/ADS-B environment where the aircraft identification will be used to correlate the flight plan instead of the mode A code. [1] US: Used exclusively by ADS-B aircraft to inhibit mode 3A transmission. [3] US: Non-discrete code assignments in accordance with FAA Order JO 7110.65, 5-2.

Traffic information service – broadcast (TIS–B) is an aviation information service that allows pilots to see aircraft that are not emitting ADS-B data but have a basic transponder. As aircraft are discovered by primary radar and respond with encoded altitude information, this information is broadcast over ADS-B.

Airport Surveillance Radar is beginning to be supplemented by ADS-B Automatic dependent surveillance-broadcast in the US and other parts of the world. As of Spring 2011, ADS-B is currently operational at most ATC facilities in the US. ADS-B is a GPS based technology that allows aircraft to transmit their GPS determined position to display ...
ADS-B-equipped aircraft with ITP software can fly more often at more fuel-efficient or less-turbulent flight levels. [102] Equipment standards are complete and ready for manufacturers to produce the necessary avionics. [103] The FAA is developing IM applications that use ADS-B In to sequence and space aircraft pairs.
