    en.wikipedia.org/wiki/Automatic_Dependent...

    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 ...

  3. DO-242A - Wikipedia

    en.wikipedia.org/wiki/DO-242A

    It contains minimum aviation system performance standards (MASPS) for Automatic Dependent Surveillance-Broadcast (ADS-B). These standards specify operational characteristics that should be useful to designers, manufacturers, installers, service providers and users of an ADS-B system intended for operational use on an international basis.

  4. Aviation transponder interrogation modes - Wikipedia

    en.wikipedia.org/wiki/Aviation_transponder...

    This is the type of transponder that is used for TCAS or ACAS II (Airborne Collision Avoidance System) functions, and is required to implement the extended squitter broadcast, one means of participating in ADS-B systems. A TCAS-equipped aircraft must have a Mode S transponder, but not all Mode S transponders include TCAS.

  5. Traffic information service – broadcast - Wikipedia

    en.wikipedia.org/wiki/Traffic_information_service...

    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.

    The Avenger Air Defense System, designated AN/TWQ-1 under the Joint Electronics Type Designation System, is an American self-propelled surface-to-air missile system which provides mobile, short-range air defense protection for ground units against cruise missiles, unmanned aerial vehicles, low-flying fixed-wing aircraft, and helicopters.

  9. CCIR System B - Wikipedia

    en.wikipedia.org/wiki/CCIR_System_B

    In most countries, the channels on the UHF bands are 8 MHz wide, but in most system B countries transmissions on the UHF channels still use system B specifications, the only difference being that the guard band between the channels is 1.0 MHz wider than for System B.
