Garmin GTX345 ADS-B IN/OUT Transponder

All-in-one Transponder Solution for ADS-B “Out” and “In”

• 1090 MHz ADS-B “Out” enables aircraft to operate at any altitude, in airspace around the globe.  This is the frequency required for New Zealand Airspace.
• Combines Mode S Extended Squitter (ES) transponder and optional WAAS/GPS position source³ in a single unit.
• Wirelessly stream traffic, GPS position and backup attitude² via Connext® to compatible mobile apps and aera® 660/795/796 portables.
• Easy replacement for your existing transponder, with common 1.65-inch tall form factor.

Your WAAS, Your Way

The extra-precise GPS position reference needed to meet the traffic monitoring requirements of ADS-B can be provided either by the WAAS/SBAS-compliant navigation system that you may already have in your panel — or by an optional built-in GPS position source available with your GTX 345 transponder³. However your aircraft is currently equipped, the Garmin GTX 345 series offers a simple, minimally intrusive ADS-B solution to meet your needs. For even more flexibility, optional remote mount GTX versions are available for compatibility with the GTN™ 750/650 series of GPS/Comm/Nav systems, as well as select Garmin G1000® integrated flight deck systems — all of which provide built-in remote transponder code selection and control.

In addition to 1090 MHz ADS-B “Out”, the GTX 345 also makes available the subscription-free weather and traffic display capabilities enabled by ADS-B “In” — which can be interfaced with compatible cockpit displays or streamed wirelessly via Connext to our aera 796/795 and aera 660 series portables, as well as to tablets/mobile devices by way of the Garmin Pilot™, ForeFlight Mobile or FltPlan Go apps. You can also receive ADS-B traffic position reports (and threat-level symbology) to help you see-and-avoid converging targets in busy airspace. Spoken audio alerts call out potential flight path conflicts (“Traffic, 10 O’Clock, same altitude, two miles”) to get you looking in the right direction. Meanwhile, on your display, Garmin’s patented TargetTrend™ relative motion display¹ offers a faster, more intuitive way of judging target trajectories and closure rates in relation to your flight path. 

 

ADS-B for Your Integrated Flight Deck

With a variety of compatibilities covering most fielded displays, our ADS-B enabled GTX series transponders offer the easiest NextGen upgrade path available from Garmin — especially for owners of select G1000-equipped aircraft. For these systems, a remote mount version, the GTX 345R, interfaces with either the aircraft’s existing WAAS position source for navigation or uses an optional built-in WAAS position source to meet ADS-B “Out” requirements. The G1000 series displays interface with the remote GTX transponder to provide onscreen squawk code entry and control in the conventional manner. Depending on the software version installed, your Garmin glass displays can also support subscription-free weather on the MFD — as well as ADS-B traffic targets on both the MFD and PFD displays for aircraft equipped with Synthetic Vision Technology (SVT™).

 

Altitude Encoding Made Simple

You can pair the GTX series with an optional Garmin altitude encoder to satisfy data transmission requirements for IFR. As opposed to other transponders with altitude encoding built in, the Garmin altitude encoder mounts separately on the install rack. So, should the transponder ever require removal, there’s no need for the static line to be disconnected. Which, in turn, eliminates the need for a follow-on leak check — and thus helps minimize ongoing service costs.  The GTX345 is also compatible with most existing altitude encoders in case you preffer to bring your own.

Bluetooth

Connect to Garmin Portable Navigators as well as Tablets/Mobile devices (running compatible Garmin Pilot or Foreflight Apps) for traffic and Attitude data.

Display Own Ship Altitude
