Garmin GTX 23 Remote Transponder for ADS-B Compliance

Garmin announced the GTX 23 ES remote transponder, a new remote-mounted Mode-S extended squitter transponder for Experimental and Light Sport Aircraft (LSA). The GTX 23 ES is designed for use with the G3X glass cockpit flight display designed exclusively for that market. In addition, Garmin announced that it is lowering the price of the G3X.

“We have made it a priority to lead the way in serving the Experimental and LSA market with affordable, feature-rich avionics solutions,” said Gary Kelley, Garmin’s vice president of marketing. “The new GTX 23 ES provides this market with an affordable path to ADS-B compliance. And we know that lowering the price of the G3X will open the door for more pilots to fly behind this state-of-the-art glass cockpit.”

The GTX 23 ES remote transponder delivers 250 watts of power output, auto standby and Traffic Information Services (TIS) interface. Using GPS-referenced positioning information, the extended squitter technology in the  GTX 23 ES positions it for ADS-B compliance and enables it to automatically transmit more accurate, and more useful, traffic surveillance data including aircraft flight ID, position, altitude, velocity, climb/descent and heading information. Traditional Mode S and Mode C transponders can only broadcast altitude, and thus require ground-based radar to correlate and identify the aircraft’s position.

The GTX 23 ES interfaces with the G3X display, a customizable PFD/MFD combination that features one, two or three all-glass displays; magnetometer; ADAHRS (combined air data and AHRS unit) and engine monitoring. With its building block design, customers can create a high-performance panel tailored to their aircraft.

The GTX 23 ES is expected to be available in August for a street price of $2199. For information about the GTX 23 and pricing for the various G3X configurations, visit www.garmin.com/G3X.
