The MLB100 is a light weight 978MHz datalink receiver that is designed for use with Avidyne’s display systems for receiving ADS-B traffic and FIS-B weather from the ADS-B network in the United States NextGen airspace system.
Using the 978MHz datalink frequency band (which is one of two channels available to pilots in the United States airspace for ADS-B) the MLB100 receives 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 MLB100 also receives 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).
ADS-B Products from Avidyne
In addition to the MLB100, Avidyne also offers the panel-mounted AXP340 Mode S Transponder with 1090MHz Extended Squitter for ADS-B OUT. Full reception of ADS-B IN traffic information by the MLB100 from ATC (ADS-R and TIS-B) requires an ADS-B compliant Mode-S ADS-B Out Transponder and approved position source (such as Avidyne AXP340 and IFD540, IFD440). Avidyne has also announced 1090MHz ADS-B IN capability for their TAS600A active-surveillance Traffic Advisory Systems (TAS-A Series).
