I got a question from another pilot the other day, wanting to connect a GPS to an ADS-B capable transponder.
My Avidyne TAS605 box is “ADS-B upgradeable” i.e. it should accept, via a suitable receiver, ADS-B data and merge it with the targets it obtains already (which it gets by pinging Mode C transponders). But “upgradeable” in Avidyne-speak is an interesting concept…
A lot of people are looking at radiating ADS-B but who will be able to see it?
ATC will see you anyway with ADS-B
Are you sure about that?
I am fairly sure UK ATC has no ADS-B visibility. They can see
They could, and indeed I know of an airfield not far from here where the people in the tower use the £200 ADS-B receiver for situational awareness “only”, but I don’t think ATC can use that data for anything operational.
I also don’t think the Eurocontrol tracking data stream is generated from ADS-B.
It begs the question of what exactly airliner ADS-B emissions are used for…

Correct. It’s coming from Radar position updates supplied by ANSP
As far as I am informed an installation of a Extended squiter (ADS-B) transponder with ADS-B output, conform the rules, is an major change.
Meaning for a EU-reg aircraft it need to be installed using an easa approved STC.
I do (did but will again) both.
It begs the question of what exactly airliner ADS-B emissions are used for…
TCAS uses ADS-B emissions already.
ATC ground stations and aircraft equipped with traffic collision avoidance system (TCAS) already have the necessary 1090 MHz (Mode S) receivers to receive these signals, and would only require enhancements to accept and process the additional extended squitter information.
(ex WiKi)
It can use, but does not yet.
