I spent a day at Oshkosh last Monday and had a chance to talk to Trig about their ADS-B plans.

The Trig TT22 Mode S Transponder is currently shipping and supports 1090ES ADS-B Out, if it is connected to an approved WAAS GPS position source. Up to now, approved GPS sources have been quite expensive.

The good news is that around Christmas, Trig is going to start shipping their new, as yet unannounced, TN72 GPS position source. I had a chance to see a prototype. It easily fits in the palm of your hand, weighs about 100 grams, and uses minimal power. While Trig wouldn't commit to a price, the people I talked to said that the unit would sell for less than $600.

Couple this with an ADS-B receiver ($500 - $850), an iPhone, iPad, or Android device, and a low cost app like Foreflight, etc., and you will have a full blown collision avoidance system that will accurately display and warn you about all other ADS-B and/or Transponder equipped aircraft in your vicinity. In addition you will be visible to all TCAS equipped commercial aircraft.

Trig indicated that their distributors have significant discounts available of groups and clubs that organize a volume purchase.

This is a great solution for glider pilots who fly near metropolitan airports and are mainly concerned about collision threats with other GA or commercial aircraft.

Get your checkbooks ready.

I appreciate the thread, and I'm trying to sort this out a little better. So, according to the Trig marketing info, 'the TN72 GPS receiver is a fully certified product (FAA TSO-C199) designed for voluntary equipage and use in areas outside of designated or mandated ADS-B airspace.' So when coupled to a Trig T22 transponder, it will transmit ADS-B out info to contribute to your being seen by others. Sounds good, but as of right now, as the TN72 is not a TSO-C145C GPS receiver, it may not qualify as an FAA certified ADS-B OUT device, and therefore may disqualify one from obtaining traffic services (TIS-B) and weather services (FIS-B) over your separate, even pricier, ADS-B IN setup?

Charlie, I suggest you read earlier posts by Darryl. Please do a search on this topic and read his posts. Your post suggests you would benefit from it and I am writing this as an encouragement not criticism. This is a complex problem and I can tell you from experience that even a fully certified system may not work in a glider, especially certified antennas. They are very old designs and they are not designed to provide proper signal when aircraft is constantly maneuvering (thermalling) with 45 deg bank angle.
