UAT Products

One of these 978UAT Universal Access Transceivers, transmitting a WAAS signal from an approved GPS navigator or a separate WAAS GPS receiver, will fulfill your ADS-B Out requirement.

You also may choose from available 978UATs with integral WAAS GPS—some cost less than 978UATs with a GPS receiver—or from one of these 1090ES Mode S Extended Squitter transponders, some of which offer integral WAAS GPS receivers. 

However, if your aircraft is capable of flying in Class A airspace or internationally, keep in mind that equipping with a UAT ADS-B Out solution could affect your aircraft’s resale value as the FAA’s January 1, 2020, mandate approaches.

Note: If you own an airplane with an integrated glass cockpit, check with your airframe’s manufacturer for information on available options.

PLEASE NOTE: While a 978UAT will meet the ADS-B Out requirements you have defined, other considerations could make a 1090ES solution more economical for you. Learn more here.
