US avionics giant Garmin has released a new range of transponders that are already ADS-B compliant.
The GTX 345 and 335 units are dual-link ADS-B In, which means they work on both UAT and 1090 and are compatible with Garmin systems installed across a wide range of aircraft. The ADS-B Out function is via extended squitter (ES) technology.
The GTX 345 also has ADS-B In and mates with other traffic and weather systems, whereas the GTX 335 is purely an ADS-B Out unit.
The new transponders integrate with a variety of current and legacy Garmin displays, including select G1000 Integrated Flight Decks, the GTN 650/750, GNS 430W/530W and G500/G600 systems.
“For nearly 20 years, Garmin has led the development and initial deployment of various ADS-B projects including Capstone, and today we have optimized that experience to unveil the industry’s best ADS-B solutions, now including the GTX 345 and GTX 335 ADS-B transponders,” said Carl Wolf, Garmin’s Vice President of Aviation Sales and Marketing.
“With more fielded ADS-B solutions than anyone else in the industry, Garmin remains committed to make the ADS-B transition simple, beneficial and cost-effective for everyone. Regardless of what type of aircraft you fly, where you fly or what you have in the panel – Garmin has your ADS-B solution.”
Garmin is marketing the new GTX 335 and 345 products as "all-in-one", since in addition to the transponder itself, options are available for an inbuilt, rule-compliant GPS ADS-B Out position source and altitude encoder. The GTX 345 model includes a dual frequency 1090/UAT ADS-B In receiver, which will receive 1090 ADS-B transmissions from other aircraft, however UAT and TIS-B/FIS-B services are not available in Australia.
The GTX 345, which includes a 1090MHz ADS-B Out transponder and a dual-frequency ADS-B In receiver is priced from $US4995; the GTX 335, which does not include ADS-B IN, is priced from $US2995.
Owners considering these units should consult with their avionics engineer to ensure compatibility.
