• Position
• Vg - ground velocity
• time stamp

The GPS is a bluetooth Data Logger BT-335. The control program for MAC is available here. I'll get the sensors working and calibrated and a code worked out on the Arduino with a data logger first. Then start adding things.

I have been asked why I don't just use a GPS directly plugged into the Arduino. This definately would be a better solution to use the GPS logger shield. But because I'd like to keep it VERY simple at first and I'm on a small budget, I've chosen this path.
