WAAS position source for ADS-B & ideal for your G3X/G3X Touch System
1090 ES transponders to meet the latest Federal Aviation Adminstration (FAA) rules for ADS-B “Out” compliance.
Using data from the worldwide GPS satellite network, the GPS 20A receiver generates precise information about your aircraft’s position, track and groundspeed. It then provides this information to your ES transponder’s “squitter” signal (via an RS-232 interface), which then broadcasts the data to the ADS-B ground station network for relay to ATC and other ADS-B “In” equipped aircraft in the surrounding airspace. This extended squitter technology allows your aircraft to automatically transmit more accurate and useful traffic surveillance data — including aircraft flight ID, position, altitude, velocity, climb/descent and heading information — to those tracking and controlling aircraft movements in ATC airspace. The extended squitter format can accommodate significantly more data elements than the basic Mode S transponder signal, so ADS-B system users are able to track each airplane’s flight path with much greater precision, accuracy and situational awareness.
Garmin G3X and G3X Touch package owners using the GTX 23ES transponder can easily install the GPS 20A by connecting a single RS-232 interface to provide compliant WAAS position data to the transponder for ADS-B “Out” — while providing a supplemental source of high-quality GPS guidance to their navigation and display systems. With these basic components, your system not only meets ADS-B “Out” requirements — but by simply adding an affordable GDL 39 portable or GDL 39R remote receiver, you can also access such ADS-B “In” benefits as datalink traffic with spoken audio alerts (“Traffic, Traffic”) and subscription-free U.S. weather, including animated NEXRAD radar, METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs and more. As an alternative, the GDL 39 receiver with its built-in Bluetooth® capability can also wirelessly send this ADS-B traffic and weather data to your iPad® or other devices running Connext®-capable apps such as Garmin Pilot, as well as the aera 795/796 series of portables. So, you have lots of options for utilizing the free information link benefits of ADS-B in your GPS 20A-equipped cockpit.

No. The Garmin GPS 20A box does not connect to the iPad via the G3X, only the Garmin GDL 39 or GDL 39R will sedn the ADS-B signal to the iPad.
No. The GPS 20A does not come with a GPS antenna. You must order the GA 35, part number 11-09701.
No, as the GTX 327 is a Mode C and not a Mode S transponder. The GPS 20A is only for use with the G3X.
No, the GTX 345 is a stand alone ADS-B in and out box. You do not need the GPS 20A in this case.
The GPS 20A is ADS-B out only. For ADS-B in you will be required to have a GDL 39 or GDL 39R.
Yes, all units listed will work together. You will need a GA 35 antenna to be ADS-B compliant. This can be found under p/n 11-09701.
Yes, if used in a G3X system the GPS 20A and TT22 along with the GA 35 antenna will make you ADS-B compliant.
The coax cable will have a BNC male connector to connect with the GPS 20A.
The GPS 20A is only intended for use with the Garmin G3X system on experimental aircraft. It is not designed as a standalone unit.
For ADS-B Out requirement, you would need GTX 23ES + GPS 200A + GA 35. For ADS-B IN, the GDL 39 OR 39R will be needed.
