Yes!  I have done a great deal with GPS engines.

You should be able to pick up a GPS engine for between US $10 and $20 on 
eBay.  The most common ones are the Jupiter 12 engines.  Do a search on 
eBay for "GPS engine" or "Jupiter 12".

The GPS engines use NMEA protocol, which is ASCII-based.  A summary of the 
NMEA output strings is here:

Some info on GPS engines including the Jupiter 12 manual is here:

I can find you other references as well.  If you have any further 
questions let me know.
