ADS-B - FlightRadar24 (FR24)

 

Has anyone had any luck with using the TCP socket to FLightRadar24?
Here are the options from the connection:
If I use Putty and telnet to these, there is data there. Just not sure what data it wants?
?
 

You'd want to connect to port 30002 to get the raw data. YAAC ADS-B decoder plugin processes the raw data itself.

Thank you for the quick reply.

I see when using PUTTY, via a telnet connection to the PI address and the 30002 port, a stream of stuff, but nothing shows on the YAAC map.

Here is a quick snippet.

That's interesting. Your raw packet feed records start with '@', but the ADS-B plugin for YAAC expected them to start with '*' (as the rtl_adsb program produces). I will tweak the ADS-B plugin to accept either record prefix; this will be released with the next build of YAAC.

Andrew,

Before you go through that work, are the packets correct other than the leading symbol?
?
I have been playing around with the different ADS-B receivers and found some play well together and others do not. FR24 provides it's own build. RF24 has a very clean UI and feeder compensation plan. Not to mention a cool support crew. The reason I like them. So cool if you want to support their feed, but please don't do that work if the work is more than the leading symbol.
 

It was more than a leading symbol, but it was worth it to re-review the ADS-B plugin code, which I haven't looked at for a few years.

That was interesting. Not only was it fixable, but your FlightRadar ADS-B receiver seems to be doing a much better job of receiving ADS-B frames without errors than my old RTL-SDR is. When I added unit test code to verify both packet formats would be accepted, I received no checksum errors on the packets you sent me (except where the CRC was overloaded to carry an identifier in old Mode S packets), but I had a ton of checksum errors coming out of my RTL-SDR. Probably lousy reception here due to terrain (like I can stand in my backyard and look _down_ at the antennas on my house roof, the slope is so steep) and no nearby aircraft because the wind is currently blowing the wrong way for the instrument approach that goes over my house (the few non-erroneous packets I received showed aircraft at 30600 feet altitude when the airport is at 36 feet elevation MSL, so they are probably staying above the Class B airspace).

Anyway, the plugin fix will be released with the next build of YAAC. But if you want to try it now, I've attached the updated plugin file for your convenience. It's in a ZIP file so email filters won't get annoyed; you'll have to unzip it to get the JAR file out to put in your plugins directory.

It is working well.
