Garmin to Offer New ADS-B Capabilities for GA Transponders

Garmin will make 1090 MHz ES (extended squitter) transmission capabilities an optional upgrade for two of its popular general aviation transponders.

The addition of 1090 MHz ES to Garmin's GTX 330 and GTX 33 Mode S transponders will allow equipped aircraft to automatically transmit position, velocity and heading information, which will provide superior surveillance capability for air traffic control, and is a foundation element of the FAA's NextGen (next generation) air traffic management system).

Gary Kelley, Garmin's vice president of marketing, said, "Providing a 1090 MHz ES to the general aviation market will increase situational awareness and safety of flight once the ADS-B system is fully implemented," adding that Garmin intends to ensure that its products are evolving towards that future.

Garmin says the upgrade doesn't change existing GTX 330 and GTX 33 features, including Mode S TIS (traffic information service) reception.  07-30-2007.
