Garmin’s GPS 20A Provides A Non-TSO’d Path For Meeting ADS-B Requirements In EAB/LSA Certificated Aircraft

Garmin has just announced the availability of their new GPS 20A, an ADS-B Out compliant WAAS GPS position source for experimental amateur-built (EAB) and light sport aircraft (LSA).

For experimental aircraft owners that already have a Mode S Extended Squitter (ES) transponder such as the GTX 23ES, the non-certified GSP 20A provides them with a simple, rule-compliant WAAS position source that meets the TSO performance requirements set forth by the FAA. The WAAS/SBAS position information is provided by the GPS 20A and is compatible with a wide range of 1090 ES transponders.

Garmin says that G3X Touch customers who have incorporated the GTX 23ES Mode S transponder or a GTX 330ES transponder in their EAB/LSA aircraft, can install the GPS 20A by connecting a single RS-232 interface to provide Garmin ADS-B data to the transponder to make their system ADS-B Out compliant. The GPS 20A communicates with all installed G3X and G3X Touch displays to provide a source of WAAS GPS data to the system.

The GPS 20A may also be paired with compatible third-party Mode S transponders. Additionally, a secondary interface can optionally provide industry standard GPS data to third-party systems, which can be utilized as a highly accurate WAAS GPS data source.

The GPS 20A is not an FAA-approved product and thus is not eligible for installation in aircraft holding a standard airworthiness certificate.
