From an entrepreneur & Pilot

Trig’s CEO Andy Davis started the company back in 2004.

An entrepreneur and pilot, he set out to produce a solid state and energy efficient Mode S transponder. A new generation of transponders was required to meet a European wide mandate for Mode S. At the time aircraft owners had few options available, so Andy and his team changed this. Our resulting TT31 transponder set a new benchmark in quality, capability and value.
