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 ...
At the nation's busiest airports, ADS-B Out is part of Airport Surface Detection Equipment–Model X at 35 sites and Airport Surface Surveillance Capability at nine sites. [85] Controllers can track the surface movement of aircraft and airport ground vehicles, which helps reduce the risk of taxiway conflicts and runway incursions. [ 86 ]
The data that ASDE-X uses comes from a surface movement radar located on the airport traffic control tower or remote tower, multilateration sensors, ADS-B (Automatic Dependent Surveillance-Broadcast) sensors, terminal radars, the terminal automation system, and from aircraft transponders. By fusing the data from these sources, ASDE-X is able to ...
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.
For an aircraft and the flight crew to operate in FANS airspace the avionics and flight crew must be certified. AirSatOne [2] has a dedicated FANS 1/A test station connection to the FANS 1/A Datalink backbone which allows the company to perform functionality testing in accordance with RTCA DO-258A/ED-100A and demonstrate compliance with AC 20-140C to support FANS 1/A operational approval.
The Aircraft Electronics Association reports $1.73 billion avionics sales for the first three quarters of 2017 in business and general aviation, a 4.1% yearly improvement: 73.5% came from North America, forward-fit represented 42.3% while 57.7% were retrofits as the U.S. deadline of January 1, 2020 for mandatory ADS-B out approach.

Aircraft carry ADS-B transponders, which transmit information such as the aircraft ID, GPS position, and altitude as radio signals. These radio transmission are collected by civilian ADS-B receivers located in the vicinity of the aircraft. These ADS-B receivers are only able to collect information on flights within radio-range of their position ...
