I still haven't figured out all I can do with the Parrot yet and I want one already. Are they calibrated to NIST-traceable standards? Warren Thanks Warren. Yes, the sensor is is calibrated at the chi...

...is now available.After months of alpha testing and a successful round 1 of beta testing, I have the first production batch of Ravens just about done. Since the first round of beta testing, I have ...

You are allowed as many attempts as you have rockets/money. And then some. 🙄

We're up to about almost foot of snow down here in Highlands Ranch so far. I assume the snow will have to melt off of the road to the pad, among other things, for the November launch to happen?

John, with your high flight, did it look like you got any dropouts in the Astro data?

John, I agree that in the larger rockets, GPS isn't a volume or mass problem, and if you're flying over 30kft, the extra $150-$400 shouldn't be a show-stopper, either. But reliably being in lock at a...

Ed, I agree with your goal, and I agree that if you could get two identical flights to read within 1%-2% without worrying about absolute accuracy, that would be fine. No argument there. The problem...

I know that most everyone would rather just fly rockets, have altimeters that tell us how high the rockets went, without having to talk about or know about how altimeters work or whether they're accur...

OK, i get that the balloons are sampling pressure at various altitueds. How is the altitude of the balloon when the pressure is sampled determined? GPS or radio location. The other NCR Ken works for ...

I just took a quick look at today's balloon sounding data for Denver and Grand Junction, and the 5 points I looked throughout the air column at had between 0 and 1.4% difference. Temperature, dew poin...

We could go on for a while on this topic, but it should probably be moved to its own thread. In the meantime, my position is that it's possible to use a test chamber to evaluate how accurately an alti...

If it were me, I'd use a 4' dowel, some lightweight leader string with a weight on one end and some putty to stick the string/weight on the end of the dowel. Use the dowel to get the weight through t...

Word is TRA records committee will not be accepting any altitude records over 25K without GPS including the full raw stream data capture. Baro or Accel derieved altitudes will not be accepted. Warren ...

Dont you have to pay additional 20 bucks too. Ypu would if it were slots, for a chance to win again! Absolutely. So I'm in for $40, assuming I fly again.

Yes, I'll have it.
