Altimeters on a cellphone? watch?
Anyone know about altimeters? What is the most accurate way to calculate it ---- using GPS, or by measuring the atmospheric pressure?
And I know lots of watches have an altimeter, and of course GPS devices can do it, but are there any cellphones that have it? |

probably gps or find a survey point. the barometric pressure can work but you need to know the density altitude. if you are near a small airport the local FBO could help you out

most altimeters are barometers that measure atmospheric pressure...and changes in weather can make you think you are higher/lower than you really are.
Take a look at this watch... Casio (PAG50-1V) Pathfinder Triple Sensor Tough Solar Watch iPhone 3G has GPS hardware built in, so it will support altimeter applications...like this one... www.apptism.com/apps/altimeter

You need to receive 4 satellite to get altitude. GPS is the only accurate way. Barometric pressure varies by the air temperature. It will get you close, but not as close as GPS. I don't know of any phones that give you altitude, but if that's what you want, get a cheap handheld GPS for under a $100.

I think I read somewhere that there's an app being developed for the iPhone... not sure how accurate it would be

The blackberry storm will report elevation in an app called Blackstar. Apparently there is a bug that inverses the number, but it is still giving you an accrurate number, just with a - sign on the front.

so before I board a plane again I'll make sure to ask the pilot if he/she is aware of that

All that will be left is a mangled frame and a watch.
