[Avionics Today 10-10-2014] Avidyne Corp. has introduced the MLB100 Datalink Receiver for Automatic Dependent Surveillance-Broadcast (ADS-B) In. The MLB100 is designed to provide ADS-B traffic and Flight Information System-Broadcast (FIS-B) weather information for display on Avidyne’s IFD540 and IFD440 FMS/GPS/NAV/COMs, as well as EX600, EX500 and EX5000 Multi-Function Displays (MFD).

Using the 978MHz datalink frequency band, the MLB100 receives 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 Traffic Information Service-Broadcast (TIS-B) transmissions.

Avidyne display systems that are already in service will require a field-loadable software upgrade to accommodate the MLB100 data stream.

“Our AXP340 Mode S Transponder provides ADS-B Out to comply with the 2020 mandate, and the MLB100 gives U.S.-based customers a low-cost ADS-B In solution for traffic, plus the ability to receive weather data without the monthly subscription costs associated with other broadcast systems,” said Avidyne CEO Patrick Herguth.
