Garmin GTX 345 Transponder
CALL FOR A QUOTE
Meeting ADS-B equipage rules for NextGen airspace just got easier — and more beneficial — for thousands of aircraft owners worldwide.
With the introduction of the GTX 345 series of Mode S Extended Squitter (ES) transponders, Garmin provides a one-box, one-swap solution that enables owners and operators to meet ADS-B requirements with minimal expense, downtime and disruption to their panels — while providing all the weather and traffic benefits of ADS-B “In.”
The IFR-certified GTX 345 looks and operates like a standard Mode S transponder. It fits in the same 1.65-inch high slot in your avionics stack. It boasts a bright, sunlight-readable digital display, a pressure altitude readout, handy timers for approaches and other operations, plus dedicated pushbuttons numbered 0-9 for quick and easy squawk code entry. But where other transponders leave off, the GTX 345 is just getting started. The addition of 1090 MHz ADS-B “Out” transmission capability (using precise GPS-referenced positioning information) enables the transponder to automatically output the more accurate, more dynamic traffic surveillance data that the NextGen airspace system requires. Plus, available ADS-B “In” reception unlocks even more capabilities for pilots, enabling them to display ADS-B traffic, weather and more on a variety of installed or portable displays.
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 transponder. 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.
