Hi,

What with all of this NATS ADS-B trial initiative, there should be good ways of detecting and plotting traffic now on Skydemon with a low cost ADS-B Receiver, to give us a very low cost PCAS.

So, working on a Raspberry Pi ADS-B receiver solution (super cheap! ~£50 or less - keep it open source), based on dump1090 or modesdeco2, but wondering if it's possible to adapt the FLARM interface to get traffic data displayed on Skydemon.  There is an ADSB2FLARM software module kicking around in the 'virtual radar' development community.

How does SD handle this?  Is there a better way to feed this data into SD?  Which interface would be recommended?  How about over Bluetooth?  If this is available is there a document describing the message format?

The Air-connect TCP/IP style isn't so attractive, since it's harder/more expensive to set up a WiFi Access Point with the RPi using a USB WiFi dongle.   (EDIT: Seems it's possible with a USB WiFi stick to create an AP, so maybe ok this way)

Cheers
Andy

Hi all, I'm new to the forum and am in the process of developing something similar to that described above.

I am essentially trying to emulate the service interface described here http://www.air-avionics.com/support/B104002.pdf to send ads-b positional information from raspberry pi to skydemon using the existing Flarm interface.

I was just wondering if Wobblewing had made any progress? Or if any users have any further insight into this, other than what has already been discussed!

Many thanks, James

I have been testing a Raspberry Pi ADS-B set up using PIAWARE software, which feeds Sky Demon through the CollisionAwAre app on my mini IPad. The tests have been a success, both on the ground (in my car) and in the air. I flew yesterday and picked up an aircraft flying out of Oxford Kidlington 1,400 feet above me and in my 8 o'clock. I turned towards the contact and even though I knew where to look, I did not actually see the aircraft until it was with a couple of seconds away from me. As shown on Sky Demon, the twin was 1,400 feet above me, so I as able to watch it fly safely into the haze of the late afternoon. The Raspberry Pi view of this contact gave me at least 8 nm notice of the proximity of this aircraft. My GPS (installed on the Raspberry PI) worked fine and there was no interference over the intercom.
