Oddball Question

[lolachampcar]

I am considering putting a Trigg Mode S transponder in an application where the Skyview is not suited.  I have been happy with my Skyview Mode S transponder so the Trigg unit would seem the obvious choice.

The Trigg documentation says it accepts the following GPS sources-

[ch61623] Industry standard “Aviation” protocol
[ch61623] NMEA 0183 protocol
[ch61623] Freeflight and NexNav GPS proprietary protocols
[ch61623] Garmin ADS-B protocol

Is the Dynon GPS puck a NMEA 0183 compliant device?  If it is, it would seem the obvious choice for a non-certified GPS source again, going back to that quality thing

The Dynon puck outputs NMEA, but at 38,400 baud, which I'm not sure the Trig supports. It also needs 8V power, not 12V aircraft power, so you'd need to do a bit of power supply work.

Remember, the only real use of non-certified ADS-B OUT is to wake up towers to give you traffic, so unless this plane has an on-board ADS-B traffic receiver, there's no real good reason to hook up the position source (at least in the USA.)

ADS-B IN is the easy part. There are a number of vendors for stand alone and IPad display type devices. In this case, there is an IFly720 in the glider and an AlphaMFD (else it would be getting Skyview ). I'm just a firm believer in traffic and, for traffic to be safe, you must be S-ES Out.

Thanks!

And also, if you're installing in an aircraft that requires and STC or other FAA approval (ie, certificated), then the FAA will want to see a 2020-compliant GPS on board, period (which the SkyView puck isn't).

I see Trig is working on several In receivers. By chance is Dynon using an Experimental version of the Trig receiver?

 

[Dynon]

I'm not sure which product you're asking about, but neither our GPS receiver puck nor our ADS-B receiver are from Trig. Our transponder is a custom (and TSO'd) version of their transponder though.

If you mean the Trig TA60 ADS-B receiver, note that it is only a 1090ES receiver, not 978 MHz, so it is traffic only, no weather. It's focused on the European market.

The output of this device uses an industry standard protocol so it will work with SkyView.
