A transponder (short for trans mitter-res ponder [1] and sometimes abbreviated to XPDR, [2] XPNDR, [3] TPDR [4] or TP [5]) is an electronic device that produces a response when it receives a radio-frequency interrogation. Aircraft have transponders to assist in identifying them on air traffic control radar. Collision avoidance systems have been ...
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 (or other airborne vehicles such as drones approved to fit "ADS-B Out") determines its position via satellite navigation or other sensors and ...
CVG-1, Carrier Air Group 1. 12 December 1946, U.S. Navy Letter ACL 165-46. Some CVG-1 aircraft (those belonging to VF-14), while temporary attached to an Air Task Group, rendered their tail code as " ATG ", though "ATG" was never authorized as a unit code. The Group's tail code was changed to "AB" in November 1956.
Gillham code is a zero-padded 12-bit binary code using a parallel nine- [1] to eleven-wire interface, [2] the Gillham interface, that is used to transmit uncorrected barometric altitude between an encoding altimeter or analog air data computer and a digital transponder. It is a modified form of a Gray code and is sometimes referred to simply as ...
