What in the purple hell was that???

[J. Carretero]

As per usual, I barely get the language, so leave alone trying to fully understand the Star Trek content. Still, this could serve as a "Hi!!! Life got on the way at the precise point when we were changing binary shapes -and still is-, but HI nonetheless! "...

I'd say it was a Borg Sphere and we should send me to their estimated landing point to bore and confuse their way out of this part of the galaxy. "Adaptation to incredible randomness is futile, you steampunk cyclops Mike Foxtrot's!".

Also, we once followed a "helicopter" doing over 600 knots for quite a few hours out of boredom at a fire base. Not bad for a mechanical bumblebee in terms of speed or endurance. It was either the Borg probe or a glitch reinforcing the "Foxtrot Ups can happen here; rarely, but they can" that is sure written somewhere in the terms of use (insert " but WTH do Iknow" body language here).

Cheers y'all!!

I've heard pretty good booms off obviously hypersonic meteors, likely closer to the line than most aircraft get. LONG time from sight to sound, but it's there.

Anybody know how high the Space Shuttle was when it made its double boom?

It was at about 70,000 feet when we saw it land at White Sands.

[Ray Tackett]

Also, how much of a sonic boom does a hypersonic aircraft generate when flying at or altitudes of more than halfway to the Karman Line?

I think I smell something...

Essence of Aurora?

Could be. I don't know how ADS-B reports very high altitude aircraft. Does it say "ah, it's above FL 510" or does it go higher? Also, how much of a sonic boom does a hypersonic aircraft generate when flying at or altitudes of more than halfway to the Karman Line?

Are those the ones we built in DLH at the GIG a few years ago?

Not exactly, but they are 90% the same under the hood. Both are based on a Raspberry Pi, and both use software-defined radios to tune in the appropriate frequencies. Both also use about 80% of the same software too.

Those were ADS-B In receivers, not the Out receivers. Got wx, traffic, etc. Even from the back seat of the KingAir....

Thanks. If I do it, I'll feed it to ADS-B Exchange, as they claim that they don't filter the results.

Yeah, I know, but aside from the software it gives you an idea of hardware requirements.

[John O'Shaughnessy [FCM]]

This will get you started on hardware, Steph. https://flightaware.com/adsb/piaware/build

I've got one of these feeding up into Flightaware.

Anyway, I'm thinking of getting or building an ADS-B receiver and plugging it into that website to improve coverage. I'll have to see if I can do it for under 0.1 AMUs

But missing packets will not make MACH 4+ speeds show up.

And, if erroneous data is shown on a 1 second burst of received data subject to interference, it will be corrected in the next second. There are a lot more ADS-B receivers out there than radar sensors, too, so interference at the source isn't the same problem.
