Garmin GTX35R Standard ADS-B Out Kit

Part# 11-14575
MFR Model# 010-01756-01


Advanced ADS-B “Out” Solution for Experimental Aircraft

  • Integrates with G3XTM series flight displays for fingertip control and squawk code entry
  • Satisfies NextGen requirement for ADS-B “Out” when paired with a GPS position source
  • Provides 1090 MHz ES (Extended Squitter) output for operations at any altitude, in airspace around the world
  • Simplifies installation with remote-mount design that saves panel space
  • Offers low power consumption and enhanced reliability
For nearly 20 years, Garmin has led the development and deployment of various ADS-B projects, and we’ve optimized our ADS-B solutions for experimental amateur-built and light sport aircraft. The GTX 35R ADS-B transponder integrates with Garmin G3X and G3XTM Touch to provide you quick, cost-effective and powerful ADS-B “Out” capabilities you can control through your flight display.

ADS-B Integration

This simple, elegant solution meets the Dec. 31, 2019, requirements for ADS-B “Out.” Offering a 1090 MHz ES “Out” signal that meets worldwide requirements for flight at any altitude, GTX 35R interfaces easily with your G3X series flight display and a GTNTM 650 or GTN 750 navigator, a GNS™ 430W or GNS G530W series navigator or a GPS 20A ADS-B position source. This automatically outputs more accurate — and more useful — traffic surveillance data to ATC, including aircraft flight ID, position, altitude, velocity, climb/descent and heading information. And by simultaneously broadcasting this information to ADS-B “In” display-equipped pilots, GTX 35R enables them to essentially see the same traffic picture for their location that ATC views on the ground.

Installation Ease

As a remote-mounted transponder, GTX 35R makes installation easy, saves you valuable panel space in your experimental or light sport aircraft and integrates seamlessly into your flight deck. Manage squawk code entry and transponder control with only a few touches of your G3X series flight display. Plus, it’s an all solid-state design, which makes for lower power consumption and enhanced reliability, compared to earlier-generation transponder technology. GTX 35R uses the GSU 25 Air Data Attitude Heading Reference System (ADAHRS) for IFR altitude-encoding information. With more fielded ADS-B solutions than anyone else in the industry, Garmin is making the ADS-B transition simple, beneficial and affordable for everyone — regardless of what type of aircraft you fly, where you fly or what you have in the panel.

Q: I would like to know whether the GTX 35R standard kit is a transponder that complies with ADS-B out standards(experimental aircraft-going into a Glasair II RG). Does it connect to a Garmin GTN 650 and can it be controlled from the GTN650?

The gtx 35r is designed as a remote mount ads-b option for the experimental g3x system. It is controlled via the g3x display.

Q: I want a simple installation, G3X Touch 450, and the GTX35R. I prefer only one GA35 WAAS antenna on the airplane. So, can the G3X GPS signal be shared with the GTX35R?

You can have the GPS signal sent to the G3X and that unit can distribute the signal to all the others. However you cannot split the signal at the antenna.

Q: Do I really need the GPS20A in a G3X system with the GTX35R to get WAAS position or the internal G3X GPS will do the job?

Per Garmin: "The GPS 20A is capable of providing GPS WAAS information to the GTX 35R to give it a compliant GPS position source for ADS-B out."
