Can ADS-B provide position information for Search and Rescue?

The Air Avionics TRX products look like they will be filling the gap to provide ADS-B in capability for traffic in a glider friendly way. They also have models with FLARM TX and RX so you can have both if you want. I agree with your premise entirely that a transponder with ADS-B out is the proper way to go. FLARM is just a stopgap, and not a particularly good one at that. We need to participate in the airspace system as peers with everyone else if we want to expect to be treated as peers.

The TRX product is essentially what is built into every PowerFLARM in the USA.

So can you explain what gap exists and how the TRX fills it?

"ADS-B out is the proper way to go." Proper for what? Proper for avoiding other gliders in busy glider locations, no, absolutely not. Proper in busy airspace with airliners, fast jets, GA traffic, sure. But the critical starting point there is *transponder*, especially vs. airliner and fast jet traffic. If that'a a concern get a transponder in the glider ASAP. ADS-B is secondary and can be worried about later.
