Hello Jeff! Hey, are you going to ROCstock?
I think this is similar to what James put together for TCC.
Again, I don’t think the Board is interested. Otherwise, I think they would
say something about this.
I know it’s another ‘thing’ but it doesn’t look like it would be difficult to
maintain once set up. And, I also think I saw grant money ($250) available on
TRA’s website for equipment or outreach.
Having this kind of technology wouldn’t be bad to have at a launch, would it?
I have seen HP rockets launched many times when there are commercial and small
aircraft over the range. But, I’ve been to many ROC launches. Like at the end
of a launch last year. The rocket launched and then we saw the aircraft. It
looked close, but I know it’s difficult to tell from the ground. There was a
long silence while we watched the rocket and the aircraft. And, how can I say
that. Well, because it’s true, and other people know it’s true. And, that’s
the reason to bring stuff like this up.
Anyway, I think ideas that are shutdown immediately with, “OK, then you get the
equipment and do it all the time” have developed as a kind of knee jerk defense
mechanism. I think this developed when ROC became less of a team and more
person dependent.

FYI Flightradar24 makes use of a network of ground monitoring stations
feeding the received ADS-B signals to their server. Here:
https://flightaware.com/adsb/flightfeeder/ ;
<https://flightaware.com/adsb/flightfeeder/>
You can also build your own setup:
https://flightaware.com/adsb/piaware/build ;
<https://flightaware.com/adsb/piaware/build>
If there are few local receivers online then your data will be inaccurate,
which includes altitude, course, and ID. I live where the mountains interfere
with the received signals. You often see altitude and course suddenly change
as the aircraft goes in and out of coverage, and sometimes it will draw a
dual trace for the same aircraft. You shouldn't really take the data at face
value, it does require paying attention.
This may not be an issue at Lucerne but might be at more remote locations.
Having a local receiver might help.

Thank you for the info James. I don’t think the ROC Board is interested in
this at the moment. I’m going to use the flightradar24 app that Andrew
suggested. It’s interesting just watching the air traffic.
And, no, I wouldn’t watch the screen during a whole launch. But, before I
launch a rocket of mine, yes, I would check the app first. And, I want to
learn more about what it has to offer.
Just check out air traffic around the Hawaiian Islands with the eruption on
Hawaii. Interesting stuff, but sorry, going OT.

I didn't spend the launch monitoring my screen at LDRS.
And ... I spotted 4 airliners in our area at LDRS (two UA, 2 AA), all at
FL30 above us.
Maybe you saw the ADSB setup that David brought to LDRS, similar but better
UI.
I keep mine under the table. I also modified the code to alert me when
something is within 4nm
of our launch site. I can give you the patch if you're interested.

Easy and cheap, and if you want to spend the entire launch sitting and
monitoring your screen.
ROCstock would be a great launch to test it.
See how much useful information you actually get and report back.
