Garmin ADS-B Upgrade Adapted to Existing Avionics
The system uses Garmin’s GTX 3000 Mode S extended-squitter transponder, GDL 88 ADS-B datalink and a FlightStream wireless gateway.

Garmin has devised a stand-alone automatic dependent surveillance-broadcast (ADS-B) system that satisfies global ADS-B requirements, yet leverages existing avionics equipment to alleviate the need for expensive flight management system and cockpit display upgrades.

The new system employs Garmin’s GTX 3000 Mode S extended-squitter transponder that broadcasts aircraft position information, GDL 88 ADS-B datalink and a Flight Stream wireless gateway to provide compliant ADS-B OUT capability in conjunction with existing Garmin avionics equipment. The system is integrated with TCAS and other systems.
