How Do The PerfectFlite Altimeteters Work?
Just wondering what kind of sensor(s) is used in the PNut altimeter.
I'm guessing it uses a radar altimeter, or does it use a GPS or barometric pressure sensor?

Almost all model rocket/hobby altimeters use barometric pressure sensors.christheman200 wrote:Just wondering what kind of sensor(s) is used in the PNut altimeter.

You betcha. (Working on my Minnesota accent)
Ran short on time, but wanted to followup with this-
GPS, The military won't let us use the accurate GPS signals. So GPS readings will always be purposfully quoted with large margin of error. Also, heavy.
The radar sounds like fun but perhaps a bit expensive and heavy.

Re: How Do The PerfectFlite Altimeteters Work?
Nobody we know of outside NASA and maybe Armadillo Aerospace (and the like) use radar altimeters. They are just too bulky for a small rocket. As far as GPS is concerned, the accuracy is much lower in the vertical direction than it is in the horizontal direction. The PNUT we don't know for sure what it uses. Possibly an accelerometer? You can probably find out with a google search.christheman200 wrote:Just wondering what kind of sensor(s) is used in the PNut altimeter.

"The Pnut utilizes a precision pressure sensor and 24 bit delta sigma analog to digital converter to obtain an extremely accurate measurement of the air pressure surrounding your rocket. "

It had to one or the other methods. Some altimeters seem to combine both methods as well.bugwubber wrote:From the pnut manual obtained through a google search ;-)U.S. Water Rockets1 wrote:Nobody we know of outside NASA and maybe Armadillo Aerospace (and the like) use radar altimeters.
