Maybe I need to get on the listserver, because the following is just pure B.S.: The newer MPX2102 actually has no cliff in lower pressure, but the relative error at low pressure increases dramatically...

Post-processing data offboard is almost certainly a non-starter for most flyers. I think 10% accuracy and a successful deployment is fine for most flyers. But if you're filling out a record form to T...

I hate to keep disagreeing, but hopefully I can do it without being disagreeable: Measuring delta-pressure with 1%-2% accuracy is very do-able with today's altimeters without any price increase. A 0.5...

But if I fly a rocket against someone else's - and it’s for any kind of contest, club record, or Tripoli record - I want if to be an apples-to-apples comparison. It seems to me that a shorter, smaller...

The baro sensor sensor would put out good data, but it wouldn't get recorded because the Parrot uses the accel to detect the launch. Either end up is fine (new feature) but sideways wouldn't work. H...

The Rocketry Planet article claimed that only the G-Whizz unit is OK over 34K MSL. What about the Missile Works and PefectFlite high altitude products? Jim claims 40K, and PF claims 45K. Adrian, I und...

Isn't there a way to adjust the SAM for ambient temperature? I would be very surprised if there weren't. Yes, that's what I was proposing in method #1 for the post-flight adjustment. Denverdoc found ...

It's a tough call, but Curt goofed. Now if he brought calibration data that showed that particular baro altimeter has good data at those altitudes and I were Tripoli's contest director, I would accep...

Hold on there Adrian. You sure that wasn't something else that was harvested and tossed over the fence into your Aero Garden??? LOL. If they did, they broke into our kitchen. 🙂 The AeroGarden is a ...

When life hands you lemons, make lemonade. And when your wife hands you a sandwich baggie full of mint harvested from an overgrown AeroGarden, made mojitos. But don't expect to be able to write clea...

I've missed a bunch of threads and pardon me if you've answered this already - but is the key element of difference in the temperature compenstion based on the US SAM -6.5c/KM assumed temperature diff...

By the way, the Tripoli record form does ask for ambient air temperature and pad altitude, so if they have that data from every record, then they could correct all of them, at least assuming that the ...

The Parrot does measure chip temperature along with every pressure measurement, but I don't recommend that for this purpose because the temperature of the board can be way off from ambient. In Chris'...

Some of you may have already seen this topic on TRF or the forums on RP, but I wanted to get this out to more people: A thread on altimeter accuracy on TRF got me doing a little more research into the...

Good to know. Somone should probably remove the 7/13 launch from the launch schedule on the web site.
