Marc beat me to the same post.

Now we will need to see if any manufactures will actually be able to justify doing the work needed to ship a TSO-C199 system. The negative view of this yet more ADS-B fragmentation for a small USA market. But the GPS direction in TSO-C199 is a great improvement... it is an opportunity for a manufacture to do qualifications needed to ship a TSO-C199 based system that could use a much simpler GPS that requiring a full TSO IFR GPS source as currently required. But that system would then still *not* meet the 2020 carriage mandate requirement for ADS-B Out (which gliders are exempt from anyhow) -- so it does not help GA in the USA in any way--although if stuff worked really well there it might help put pressure on changing other requirements.

TSO-C199 devices are a reduced feature Mode-S (and optionally 1090ES Out) based traffic saftey beacon system hopefully suitable for gliders, balloons and maybe UAVs inter-operating with GA and above aircraft equipped with PCAS/TCAD/TCAS/ADS-B In. And to be clear TSO-C199 is not and never will be an invitation for aircraft owners to connect COTS (common off the shelf) GPS systems to an ADS-B Out transmitter. It is really important that TSO-C199 is based on transponder technology, that makes any TSO-C199 based system, if it is developed, compatible with TCAS, ... remember the ASG-29 and (TCAS equipped) Hawker 800 midair out of Minden a few years ago, TSO-C199 is a direct response from the FAA to the NTSB findings in that accident.
