One of these 978UAT Universal Access Transceivers with an integrated WAAS GPS receiver will fulfill your ADS-B Out requirement. You also may choose from available 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.

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.
