Remote-mount 1090 MHz ADS-B “Out” Transponder Solution

• Satisfies NextGen equipage requirements for ADS-B "Out"
• 1090 MHz output enables aircraft to operate at any altitude, in airspace around the globe
• Compatible with a variety of Garmin cockpit displays – including G1000® and GTN™ 750/650 series – which offer transponder code entry and control
• Remote-mount configuration saves vital space for avionics in your panel

Offering a simple, affordable solution for pairing with select G1000 and GTN 750/650 series avionics, Garmin's GTX 335R remote-mount transponder provides the ideal upgrade path for aircraft operators looking to satisfy NextGen requirements for ADS-B "Out" capability. Note that the Diversity model does not offer an optional built-in WAAS GPS position source.

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.
