En Route: Garmin® unveils the next generation of all-in-one ADS-B transponders

GTX 345/335 provide simple upgrade path for thousands of aircraft worldwide

Garmin International Inc. has announced GTX 345 and GTX 335 all-in-one ADS-B transponders that include Extended Squitter (ES) ADS-B Out, with options for built-in WAAS, as well as dual-link ADS-B In. The transponders will integrate with a wide variety of current and legacy Garmin displays, including select G1000® Integrated Flight Decks. The GTX 345 displays ADS-B traffic, subscription-free weather, GPS position data and back-up attitude information on the popular Garmin Pilot and ForeFlight Mobile apps via Bluetooth® and Connext wireless technology. The GTX 345/335’s size makes it easy to replace the most popular transponders, like the Garmin GTX 327 and many others. Remote options are also available for compatibility with the GTN 650/750 series and G1000-equipped aircraft.

“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.”

The GTX 345 and GTX 335 incorporate the popular 1.65-inch tall transponder height and boast a bright, sunlight-readable digital display, including pressure altitude readout, dedicated buttons for numeric squawk-code entry and a built-in timer. An option for an integrated WAAS/GPS position source provides operators with an all-in-one solution that meets ADS-B Out requirements. The GTX 345 pairs with compatible displays to add subscription-free Flight Information Service-Broadcast (FIS-B) weather and ADS-B In traffic, incorporating exclusive features such as TargetTrend and TerminalTraffic.


345 includes a dual-link ADS-B receiver that provides pilots with a complete picture of ADS-B-equipped traffic. When paired with an active traffic system, the GTX 345 combines ADS-B traffic targets and active traffic targets to display a comprehensive traffic picture. Beyond the display, the GTX 345 may be integrated into the aircraft’s audio panel to provide ATC-like audible alerts, such as “Traffic: ten o’clock, same altitude, two miles” to help pilots keep their eyes outside the cockpit when looking for traffic. Additionally, an optional altitude encoder is available and conveniently mounts on the tray of the transponder for easy installation and service, precluding the need for a static check.

For select G1000-equipped aircraft, either with or without WAAS, a remote-mounted version of the GTX 345 or GTX 335 takes the place of the aircraft’s transponder and interfaces with either the aircraft’s existing WAAS position source or the optional WAAS position source to meet ADS-B Out requirements. The G1000 display interfaces to the transponder to provide squawk code entry and control in the same manner as before. The dual-link GTX 345 provides the capability to display various ADS-B In benefits (software version dependent), on the primary flight display (PFD) and multi-function display (MFD). Pilots may view subscription-free weather, including NEXRAD, METARs and TAFs on the MFD, as well as ADS-B traffic targets on the MFD, and for aircraft equipped with Synthetic Vision Technology (SVT™) traffic targets also appear on the PFD. With built-in Connext technology, additional ADS-B In benefits can be wirelessly streamed to a Garmin GPS portable like the aera® 796/795 and the most popular apps in the industry, Garmin Pilot and ForeFlight Mobile. In addition to G1000, the GTX 345 integrates with thousands of installed displays to provide the benefits of ADS-B In, further extending existing avionics investments.

The GTX 345 transponder is available with and without WAAS for a list price of $5,795* and $4,995* respectively. The GTX 335 ADS-B Out transponder is available with WAAS for $3,795* and without WAAS for $2,995*. Remote-mount derivatives of the GTX 345/335 share pricing equivalent to the panel-mount transponders. For additional information visit: www.garmin.com/ads-b.T&T
