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

Can anyone recomment a small size, low cost, low power GPS receiver with
velocity, position and height serial data output ? (It will be used in a
model airplane for data logging)

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 : http://www.laipac.com/
e.g. GPS engine like TF30
small - 30x40x7mm
low cost - $75 + $20 for active antenna
low power - 3.3V, 50mA
code to interface to a PIC microcontroller provided.

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. Jan Kansky wrote up a
nice tutorial at:
http://www.jeklink.net/projects/GPS_...Sailplane.html

I've logged speeds in excess of 100 mph,using the GPLIGC program, but
you have to be aware that this is ground-speed, that the GPS measures,
so when you get to the edge of your vision, and split-S back, the
speed momentarily drops to zero.
