Garmin GTX 335R
The Ultimate ADS-B "Out" Solution
Introducing the Garmin GTX 335R, the ultimate ADS-B "Out" solution for meeting NextGen requirements with ease and reliability. This remote-mount transponder features a 1090 MHz output for global operation at any altitude and combines a Mode S Extended Squitter (ES) transponder with an optional WAAS/GPS position source. Compatible with Garmin cockpit displays like the G1000® and GTN™ 750/650 series, it allows straightforward transponder code entry and control. With its all solid-state design, the GTX 335R offers enhanced reliability, lower power consumption, and precise GPS-referenced positioning, providing accurate traffic surveillance data and faster updates. FAA-approved for many popular aircraft models, the GTX 335R ensures a seamless, economical, and worry-free transition to ADS-B operations.

Offering a simple, affordable solution for pairing with select G1000 and GTN 750/650 series avionics, our GTX 335R remote-mount transponder provides the ideal upgrade path for aircraft operators looking to satisfy NextGen requirements for ADS-B “Out” capability. The unit is also optionally available with a built-in WAAS GPS position source¹ so everything needed to meet the ADS-B equipage rules can be provided with this all-in-one upgrade package installation.
Your Cost-effective Upgrade to NextGen
With more fielded ADS-B solutions than any other brand in the industry, Garmin is committed to making the transition to NextGen airspace as simple and straightforward as possible. The IFR-certified GTX 335R is a prime example. It’s an all solid-state design, which makes for lower power consumption and enhanced reliability, compared to earlier-generation transponder technology. What’s more, the addition of 1090 MHz ADS-B “Out” transmission capability (using precise GPS-referenced positioning information) enables the GTX 335R to automatically output more accurate, and more useful, traffic surveillance data to ATC, including aircraft flight ID, position, altitude, velocity, climb/descent, and heading information. Conventional Mode S and Mode C transponders can only broadcast altitude and squawk code which means they require ground-based radar to correlate and identify the aircraft’s position on the controller’s radar screen.
Enhanced Traffic Surveillance
Using 1090 MHz extended squitter ADS-B “Out” transmission, the Garmin GTX 335R improves upon the existing transponder query system – while working seamlessly with existing ATC protocols. The ADS-B reports provide ground controllers with considerably faster updates than traditional radar. And by simultaneously broadcasting this information to ADS-B “In” display-equipped pilots, it enables them to essentially see the same traffic picture for their location that ATC is watching on the ground. For aircraft that may prefer or require a diversity solution, GTX 335R is available in a diversity configuration which utilizes two antennas — mounted on the top and bottom of the aircraft — to provide superior operational coverage.
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 335R, 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.
Altitude Encoding Made Simple
In addition to its WAAS-enabled position reporting capabilities, the GTX 335R can also be paired 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.
An Easier Path to NextGen
For decades Garmin has led in the development and deployment of ADS-B technology. Today, the Garmin GTX 335R series is being FAA approved for installation on hundreds of today’s most popular aircraft makes and models. It’s clear that with the all-in-one GTX 335R solution, Garmin is working to make your transition to ADS-B operations as simple, economical and worry-free as possible.
