Trig Transponder GPS input from Pilotaware FX

[Hap Hazard]

Hi All,
Was hoping to get some sort of answer to this question so I understand the system and benefits a little better. I had previously installed a "Air Avionics" traffic display to declutter my small nav screen (tablet), which is to be powered through my RS232 port of the DX. I am trying to weigh up the benefits of also providing a signal from the FX unit to the Trig Mode S transponder as well, but in order to provide both devices with info from the FX unit, I will need to fit a splitter.
I am trying to understand the benefits to me and other users by fitting a GPS signal to the Trig, which I guess will give other Transponder users only a bit more info (there probably isnt that many out there these days?).
So I can weigh up the pros and cons and understand the overall systems better (as I only have a very basic understanding), I am trying to decide if its worth investing in even more hardware and its complexity, or simply forget about feeding a GPS input into the Trig.
Regards,
Bruce

Hi Bruce,
Connecting a GPS signal to your Trig transponder will give out an ADS-B Out capability.
This will allow other aircraft, which are equipped with an ADS-B IN receiver, to detect you.
It will complement your current PAW/FX transmit capability...

Very beneficial and will make you more visible to a lot more aircraft.

Having said that, you only need to get a GPS position to your transponder, so if you have something like a Kanardia Horis in your panel you can always take a feed from that. It doesn't have to be from your FX but it is another (convenient) way of doing it.

At the risk of being the party pooper, if you connect an uncertified GPS signal to your transponder you will have to configure the ADS-B as uncertified/SIL=0 so a lot of stuff (certified) will screen you out. Transponders don't receive traffic information and the majority are flying mode S so you will only see them via bearingless or MLAT.

If you can simply connect GPS data to your Trig with an extra lead, I'd do it anyway.

If it's more complex than this, I'd pass.  Horus to Trig sounds pretty good to me. Then you have two separate positional EC systems with separate GPS sources.

Steveu,
To avoid confusion, I think some clarification is needed regarding your slightly confusing comments:
"... so a lot of stuff (certified) will screen you out...."

I think you meant to say that airliners and "high end GA", equipped with very fancy and expensive integrated Traffic displays, MAY screen out SIL/SDA=0 ADS-B data.
Most "normal" end GA (our aircraft types), equipped with lower cost ADS-B In receivers, will still see and process SIL/SDA=0 ADS-B data.
Also, our certified Mode S/ES transponders will still interact with aircraft that are equipped with TCAS..
Hope this helps..

Thanks guys,

Just ordered up a splitter....

Cheers,
