Small portable units is not where the vision of ADS-B started,

I don't say it was where it started but it was part of the vision expressed at an FAA conference in the 1995/6 timeframe. Unfortunately I can't find the exact dates of the conference or locate any minutes but I was in attendance as a member of the NASA HSR XVS team. Since we were working on developing an aircraft with no forward facing windows we had a keen interest in detecting anything large enough to be collision hazard.

Maybe you can track down some record of the conference. All I remember is 1995/6 and location Arlington.

We have a bunch of ADS-B (out) capable transponders that will be going into aircraft in the next few years (at least the only one I'm willing to install is going to have that capability).

EXCEPT we don't have a FAA approved GPS data source for the ADS-B out function available without installing another (read that expensive) GPS device in our crowded panel.

In Europe you can use any GPS source for ADS-B out.
In my glider I'm using the GNSS-FR as a gps source to supply the NMEA RMC to my mode-s transponder.
This works very nice.
Occasionally there are a few spurious fixes, but I have also seen this with professional installations (airlines, etc)

I'd post a sarcastic reply about usual European vs. USA aviation regulation and bureaucracy, but I can't find the right forms I need to do this.
