Using GPS on cell phone to track a weather balloon to 90,000 feet.

On September 5th, I launched a weather balloon with a payload containing a GPS unit and a Canon digital camera. My mission: capture the curvature of our earth on camera. GPS technology was to be handled by a Boost Mobile Motorola i290 cell phone, loaded with software to track it online. When the GPS unit failed, the project was considered as good as lost... until 16 days later, when a farmer working his field found it in North Texas! My contact information taped on the package allowed for him to call me and let me retrieve my "goods"! The results were amazing, producing pictures in our Stratosphere at an altitude of almost 90,000 feet.

You can read more about it at . The Pilot Point Post Signal recently did an article on the launch as well ( )(digital download).

Just wanted to share my story, as I find it amazing and truly breathe taking when you see what I accomplished with such a small budget.

The phone's SIM card failed, and I lost connection to it through the software that was suppose to report GPS coordinates when it was in range.

Signal is usually lost under 30k since no phones will work usually above that elevation.

Funny, I've recently "thought" of doing this very thing recently with an old phone. Wondering if it's even possible here in New England, or will this dog land in the Atlantic?

I'd like to talk to you about it if you've ever got the time.
