$100 ADS-B receiver for Dynon/Garmin

Explored Flightradar24 further and found the following link:

Seems to be a very neat site.

ISTR the Dynon uses the standard GTX330 format for their ADS-B data, so any device that outputs this will show as traffic on their displays.

The GTX330 Manual covers the data output which appears to be a derivative of the ARINC429 protocol orperhaps ARINC 429 itself -I'm not an engineer so I leave that to you ...

Anyway, it shows the labels used, threats, ranges etc. on pages 5-12 & 5-13.

Thanks! Now can anyone point me at ARNIC429 protocol docs? I can't find any on the web.

Hi Kevin

Have a look at;

A technicality - our ADS-B box actually uses an unpublished format that gets traffic and wx together from the box - so you can't emulate the actual ADS-B connection. But, you're right, we also support traffic input via the TIS format on any of SkyView's serial ports. Anything that can spit out TIS can also be displayed on SkyView.

this spec tells you how to read the data. I hope this helps.

This is real homebuilding keep up good work guys.

Any update on this Kevin ?
I use a DVB-T stick and get many aircraft just with the included antenna, im going to make a bigger antenna for out side and see how that goes.
For $20 outlay, and the free software, this is FUN on the cheap !

Per Radomir's suggestion,

I bought one of the <$20 software definable radio sticks:



And had it running in about 15 minutes and it works surprizingly well!

Tons of work out on the net has been done with these radio's. I caught my short flight today by recieving my Mode S/ES squawk and uploading it to FlightRadar24 live. This is totally done via this receiver sniffing my Mode S/ES xponder signals... Little antenna stuck to the roof of my truck sitting on the ramp at the airport.






Pretty cool stuff but it is scary. If I can do this for a hobby, what prevents some terrorist from doing it and sticking one of these things on the nose of a missle?

SDR stick....If someone can write a software front end and decoder to be able to pull out the Mode S/ES aircraft buzzing around, there should be someone that is smart enough to write one for the 978 band and decode the FIS-B data.

This is way over my head However it is where the world is at! If you can figure out how to display ADS-B info on either a 430 or a 396/496 I and many more in the certified world would be interested. I dont think the FAA can regulate what we do with data. The world it is a changen. Thanks for you knowledge and work.
