If you already own a suitable Trig transponder then our TN70 kit is the easiest way to become ADS-B compliant. The TN70 includes a certified WAAS GPS and companion WAAS GPS antenna, designed to enhance your aircraft via a simple install that will deliver excellent ADS-B Out performance. The TN70 takes no panel space, it’s fitted discretely as a standalone GPS so you can retain and use your existing panel equipment. Each TN70 includes an install kit for the WAAS GPS and fixing screws for the WAAS antenna along with relevant FAA 8130 certification.

If you need a Trig transponder to complete your TN70 ADS-B solution, then simply add one of our class leading products certified to TSO C166b, the latest ADS-B standard. A Trig transponder is the hub of an ADS-B Out system, using extended squitter to communicate with ground stations and suitably equipped aircraft. Trig transponders use 1090ES technology – the ICAO’s International Standard.

Trig has an established STC program and U.S. based FAA certification partner, Peregrine of Denver. Certified aircraft owners who buy a TN70 are eligible to receive a free FAA STC data pack from Peregrine. If you are based outside the U.S. then please consult your Approved Trig Dealer. There may be value in using the Trig STC as a template for subsequent approval within your local ADS-B certification regime.

Trig is also a partner with the U.S. NextGen ADS-B Fund. This is a general aviation loan initiative designed to cover the cost of both your ADS-B hardware purchase and install costs, making it even easier to become compliant. For more details go to
