Glossary of TermsADS-B: Automatic Dependent Survelliance Broadcast. Next generation ATC system permitting air to air communication and air traffic coordination without the involvement of a ground station. AOPA: Aircraft Owners and Pilots Association ATC: Air Traffic Control ATCAC: Air Traffic Control Advisory Committee ATCRBS: Air Traffic Control Radar Beacon System DABS: Discrete Address Beacon System (aka "Super Beacon", "Mode S") FAA: Federal Aviation Administration FRUIT: False Replies Uncorrelated in Time Garble: data corruption caused by receiving multiple signal replies when only expecting one IFF: Identify Friend or Foe - a system for electronically differentiating between friendly and enemy aircraft LL: Lincoln Labs modulation: the process in which a bitstream is converted to a waveform compatible with a transmission channel Mode A: Transmission of unique identifer in ATCRBS by planes. Also used in Mode S. Mode C: Transmission of altitude in ATCRBS by planes. Also used in Mode S. Mode S: Mode Select - a bidirectional one-to-one data-link for ground to air communication SLS: Sidelobe Suppression. A technique originally used in ATCRBS and employed in Mode S which temporarily suppress planes from responding to interrogation signals if a plane is hearing the leakage of signal directed to another plane (sidelobe). This prevents planes from responding to signals not intended for them. TACAN: Tactical Air Navigation System TCAS: Traffic Collision Avoidance System TIS: Traffic Information System - a low-cost traffic collision and avoidance system based on the Mode S data-link |
