978MHz ADS-B Solutions for Whatever You Fly

Using the 978MHz datalink frequency band, which is one of two channels available to pilots in the United States airspace for ADS-B, Avidyne’s SkyTrax100 Receiver provides Flight Information System-Broadcast (FIS-B) weather information, including NEXRAD radar, METARs,TAFs, AIRMETs, SIGMETs, Special Use Airspace (SUA), and Temporary Flight Restrictions (TFRs). The SkyTrax100 will also receive traffic information* directly from nearby 978MHz-equipped aircraft, and indirectly through the rebroadcast of 1090MHz-equipped aircraft via 978MHz ADS-R. Traffic information from aircraft not participating in ADS-B is received from ground stations via 978MHz TIS-B transmissions (Traffic Information Service-Broadcast).
