There are several OEM receivers available - all the major GPS manufacturers
have them. The cheapest one (as of early '96 - may have changed now) was the
Rockwell Jupiter. This is a 12 channel receiver with a TTL level serial
 interface,
on a board about 2"x1". The price here was around the AUS$250 mark. The other
manufacturer to check would be Trimble. Both these companies have web sites,
which at last check, did not have a huge amount of information, but should
have contact details.

A warning; the interface protocol for the Rockwell receiver is either NMEA
or Rockwell proprietary binary format; the NMEA spec you have to buy (you can
find some details on the Web), and Rockwell will not sell you the proprietary
spec unless you buy their development kit for $1000+. The kit is just docs, a
receiver, and a desktop housing with RS232 converter (and probably an antenna).

For an antenna, you can buy them ready made, or I did see some info on the web
about making your own.
