  2. Automatic Dependent Surveillance–Broadcast - Wikipedia

    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. Aviation transponder interrogation modes - Wikipedia

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

    Upon interrogation, Mode S transponders transmit information about the aircraft to the SSR system, to TCAS receivers on board aircraft and to the ADS-B SSR system. This information includes the call sign of the aircraft and/or the aircraft's permanent ICAO 24-bit address (which is represented for human interface purposes as six hexadecimal ...

  4. 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.

  5. Airport surveillance and broadcast systems - Wikipedia

    en.wikipedia.org/wiki/Airport_surveillance_and...

    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 ...

  6. 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.

  7. Aireon - Wikipedia

    en.wikipedia.org/wiki/Aireon

    Aireon was launched in 2011 as a joint venture between satellite communications company Iridium Communications Inc, Nav Canada, NATS, [5] ENAV, [6] Naviair [7] and the Irish Aviation Authority to work on a surveillance system to track aircraft around the globe, beyond the range of ground-based radar and ADS-B receivers, in real time.

  8. 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.

  9. Receiver autonomous integrity monitoring - Wikipedia

    en.wikipedia.org/wiki/Receiver_Autonomous...

    Receiver autonomous integrity monitoring (RAIM) provides integrity monitoring of GPS for aviation applications. In order for a GPS receiver to perform RAIM or fault detection (FD) function, a minimum of five visible satellites with satisfactory geometry must be visible to it.
