I’d say a bad backed translated to garbage.
Unless this was a Utrumpian tweet
That was a Cessna 150 just as it was spit out of the top of a thunderstorm…
“Toto, I’ve a feeling we’re not in Kansas anymore.”
I had one come up the other day at 275,000 feet. I think FA needs some “garbage” filtering, distances over say 300 nm and altitudes over 50K…
I also had a plane that claimed to be over North Carolina the other day (I’m in Kansas.) Inadiqate filtering again… It’s sad that ads-b lacks forward-error-correction.
UAT does have FEC (considerably more than Mode S) - 144 data bits + 96 RS or 272 + 112 RS for downlink frames. It can correct 6-7 errors.
FA does filter the data you supply for plausibility, but obviously you won’t see that looking at the local data directly.
Altitudes over 50k is a bad filter, balloons are regularly higher than that.
A Citation x , GS550 and 650 also can fly at FL510

Picked up a HiBal 67K and a rare dragon lady at 60K
Fair enough… I’m spoiled by WSJT JT65
JT65 is designed for high noise environments, usually on HF with ionospheric skip.
ADS-B doesn’t need the FEC as much. It is mainly used in line of site situations and sends updates twice per second. If you miss one, you can easily catch the next message (or the one after that).
