    Radar beacon (short: racon) is – according to article 1.103 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) [1] – defined as "A transmitter-receiver associated with a fixed navigational mark which, when triggered by a radar, automatically returns a distinctive signal which can appear on the display of the ...

  3. Air traffic control radar beacon system - Wikipedia

    en.wikipedia.org/wiki/Air_traffic_control_radar...

    The air traffic control radar beacon system ( ATCRBS) is a system used in air traffic control (ATC) to enhance surveillance radar monitoring and separation of air traffic. It consists of a rotating ground antenna and transponders in aircraft. The ground antenna sweeps a narrow vertical beam of microwaves around the airspace.

  4. Secondary surveillance radar - Wikipedia

    en.wikipedia.org/wiki/Secondary_surveillance_radar

    This system, which became known in civil use as secondary surveillance radar (SSR), or in the US as the air traffic control radar beacon system (ATCRBS), relies on a piece of equipment aboard the aircraft known as a " transponder ." The transponder is a radio receiver and transmitter pair which receives on 1030 MHz and transmits on 1090 MHz.

  5. Emergency locator beacon - Wikipedia

    A blind approach beacon system or beam approach beacon system ( BABS) is an automatic radar landing system developed in the early 1940s. [1] It is a responder (or transponder) mounted in a Hillman van and placed at the end of the runway. In some cases fixed sites were installed and by the mid-1950s Standard 9 vans were in use.

  7. Radio beacon - Wikipedia

    en.wikipedia.org/wiki/Radio_beacon

    In navigation, a radio beacon or radiobeacon is a kind of beacon, a device that marks a fixed location and allows direction-finding equipment to find relative bearing. But instead of employing visible light, radio beacons transmit electromagnetic radiation in the radio wave band. They are used for direction-finding systems on ships, aircraft ...

    SHORAN. A Shoran navigation shore station in Alaska's North Slope, summer 1950. SHORAN is an acronym for SHO rt RA nge N avigation, a type of electronic navigation and bombing system using a precision radar beacon. It was developed during World War II and the first stations were set up in Europe as the war was ending, and was operational with ...

  9. Radio navigation - Wikipedia

    en.wikipedia.org/wiki/Radio_navigation

    Radio navigation. Radio navigation or radionavigation is the application of radio frequencies to determine a position of an object on the Earth, either the vessel or an obstruction. [1] [2] Like radiolocation, it is a type of radiodetermination . The basic principles are measurements from/to electric beacons, especially.
