Announcement: All-In-One ADS-B Transponders

We are excited to announce the GTX 345 and GTX 335 all-in-one ADS-B transponders designed to provide a simple upgrade path for thousands of aircraft worldwide. These next generation transponders include Extended Squitter (ES) ADS-B Out with options for built-in WAAS, as well as dual-link ADS-B In. The GTX 345/335 integrate on a wide variety of current and legacy Garmin displays, including select G1000 Integrated Flight Decks.

The GTX 345 and GTX 335 incorporate the popular 1.65-inch (4.2 centimeters) tall panel-mount transponder form factor 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 aircraft owners and operators with an all-in-one solution that meets ADS-B Out requirements. Remote-mount options are also available for control and display within G1000 and GTN 650/750-equipped aircraft. 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. The GTX 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: 10 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.

Select G1000-equipped aircraft, either with or without WAAS, now have an elegant and simple path for ADS-B. 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.

The GTX 345 also integrates with thousands of installed displays to provide the benefits of ADS-B In, further extending existing avionics investments. This initially includes the popular GTN 650/750 touchscreen navigators and GNS 430W/530W navigators, aera 796/795, Garmin Pilot, ForeFlight Mobile and other third-party avionics. Compatibility is extended to the G3X Touch glass flight display and is expected in Q3 2016. Support for G500/G600 is also expected in Q2 2016. Additionally, customers may pair the GNS 480 and the GMX 200/MX 20 multi-function displays with the GTX 345/335 and use the integrated WAAS position source to achieve ADS-B Out. Pairing the transponder with a display overlays ADS-B traffic and subscription-free FIS-B weather on top of colorful, moving maps with reference to airspace, terrain, flight plan information and more, so it’s easier to identify traffic and weather of concern. FIS-B weather products include NEXRAD, METARs, TAFs, PIREPs, winds and temperatures aloft, NOTAMs, AIRMETs and SIGMETs. Exclusive traffic features such as TargetTrend and TerminalTraffic further enhance the traffic picture. Display capabilities vary, visit the Garmin website for full compatibility details.

GTX 345 customers can wirelessly receive ADS-B traffic and weather, as well as precise GPS position data for use within mobile applications and back-up attitude information from the built-in AHRS via Connext. SVT is enhanced by the AHRS within the transponder, displaying GPS-derived airspeed, altitude and vertical speed overlaid on a rich 3D topographic landscape. Wireless compatibility includes the popular aera 796/795 portable aviation GPS and mobile applications including Garmin Pilot and ForeFlight Mobile. Traffic is transformed within Garmin Pilot, which also leverages exclusive TargetTrend and TerminalTraffic.

The GTX 345 and GTX 335 transponders have received the FAA’s Technical Standard Order (TSO) authorization and is expected to receive supplemental type certification (STC) later this month for installation in hundreds of aircraft makes and models. European Aviation Safety Agency (EASA) validation is expected later this year. The GTX 345 transponder provides ADS-B In/Out capabilities and 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.
