Strange flight path - bad data?

FlightAware ADS-B Flight Tracking
1

I re-installed the Pi over the weekend, because it went offline a few days prior - easier to re-image then rebuild. For the rebuild I added AboveTustin the twitter bot, and from looking at its tweets I’m seeing some bad flight paths, for example:

If I happen to catch it, and check on the regular map I see the same into. I’m using branch 2.6 of adsbreceiver.net project, mutability build. MY twitter bot, and more examples can be found here

Thanks

That looks like bad mlat data from a non-FA source.

Try an unmodified piaware sdcard image and see if it does the same thing.

Thx obj, I’ll start there.

On the FlightAware → My ADS-B → Control Panel I set “Mode S Multilateration (MLAT)” to disabled, and this has cleaned up my flight paths. What I don’t understand, is that the stats still show that I am sending MLAT positions, thoughts?

edit Looks like I’m reporting fewer MLAT reports, about half as many.

On the plus side, I’m getting to capture some interesting flights:

Then you have another, non-FA mlat source. Using more than one mlat source is going to produce bad tracks; don’t do that.

Or more simple put, I can’t read graphs… :unamused:
