Garmin has introduced a variety of new ADS-B products to bring your existing or new avionics into compliance with the FAA mandate for ADS-B Out. If you would like more information on any of their products or are interested in having them installed, please email us. Below are just a brief overview of their versatile products.

GDL-88 ADS-B Out


Under the NextGen air traffic management system, all aircraft in controlled airspace will need to be equipped with ADS-B “Out” technology by 2020. For those who only fly below Class A airspace (18,000 ft) and in U.S. skies, the GDL 88 offers an affordable solution to reaching compliance. And even if you fly above 18,000 ft, the GDL 88 can still give you all the benefits of ADS-B “In” data – consider pairing it with a GTX 330/33 ES transponder for a comprehensive ADS-B “In/Out” solution.

With ADS-B “Out”, the GDL 88 gathers information about your position, track and ground speed from either your existing WAAS GPS source or an optional built-in WAAS receiver. It then broadcasts this information to ADS-B ground stations over the 978 MHz Universal Access Transceiver (UAT) frequencies. This gives ATC and ADS-B “In” equipped aircraft a more precise picture of what’s happening in the sky, and allows for more safe and efficient flight routing.


GTS-800 Series

In busy, high-density airspace, pilots are challenged to “see and avoid” other aircraft that may be climbing, descending, or cruising in their vicinity. Alertness and vigilance are critical. But for added protection, nothing beats the GTS™ family of ADS-B enhanced Traffic Advisory (TAS) and Traffic Collision Avoidance (TCAS I) Systems. Featuring exclusive Garmin CLEAR CAS™ technology, these innovative systems provide accurate, dynamic traffic surveillance — with ATC-like spoken audio alerts to help you quickly respond to potential flight path encroachments.  

GDL-39 Portable ADS-B In

Receive ADS-B traffic, subscription-free weather on your Garmin Aviation Portable or mobile device with the GDL 39 ADS-B receiver. When using Garmin Pilot on your mobile device, the GDL 39 can provide highly accurate WAAS GPS data as well.

The GDL 39 features ADS-B “In” datalink technology that allows it to receive subscription-free Flight Information Service-Broadcast (FIS-B) weather information over the FAA’s 978 MHz Universal Access Transceiver (UAT) uplink. Easily access animated NEXRAD radar, METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs and more right on your compatible Garmin aviation portable or through the Garmin Pilot app on your iPad® or Android device.

We have a GDL-39 Demo unit if you would like to stop by to see how it works.

Note: The GDL 39 is a non-certified receive-only product. It does not provide ADS-B “Out” capability to satisfy FAA mandate requirements.


GTX-330ES Transponder

With IFR-certified ES, or Extended Squitter, versions of the GTX 330, Garmin has taken the lead in providing an affordable pathway to ADS-B compliance for the Next Generation airspace system. Using precise GPS-referenced positioning information, the extended squitter technology enables transponders to automatically transmit more accurate, and more useful, traffic surveillance data — including aircraft flight ID, position, altitude, velocity, climb/descent, and heading information. (Compared to traditional Mode S and Mode C transponders, which can only broadcast altitude, and thus require ground-based radar to correlate and identify the aircraft’s position.)

Certified to TSO-C166b, expected Q4 2012, authorization for 1090 MHz extended squitter transmission, the GTX 330 ES 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 TAS or TCAS equipped aircraft, it enables them to essentially see the same traffic picture for their location that ATC is watching on the ground. Thus, with everyone in the ADS-B loop watching and reacting to the same flight trajectories, safe separation is far easier to maintain.
