Small, low cost, low power GPS receiver for model airplane

What's that saying in manufacturing ? ...

something like "cost, quality, quantity ... you can have any two of the three"

In engineering, that's good, fast, or cheap; pick two. There's a little more wiggle room with market positioning and volume for manufacturing.

Anything from the Garmin eTrex line would work well. They store "breadcrumbs" and also spit a serial NMEA PVT stream. The Summit model has built in altimeter and electronic compass; I expect these can be sent on the serial, as well. The eTrex are great on the motorcycle, too. They're small, well weatherproofed, and extremely rugged. Mine survived a 4 foot fall to the pavement at 60 mph three years ago, and it's still in use.

I would try it first without the datalogger, and see if the breadcrumbs have enough resolution for your needs.

Have you looked here :

This site has many links to GPS and UAV site. Good luck

I've been flying a Garmin Foretrex 201 in (on) both my Aegea Mantis and my Ultrasport for the last 4 months. It updates as fast as in 1 second intervals. It can be purchased at Amazon.com for less than $140, has a serial port read-out, and together with software available on the net, you can do all what you're asking.
