I am using a Garmin GPS-35PC. This thing looks like a computer mouse
without the buttons. It is a 12-channel parallel unit, but has no display
or keyboard. The only connections are 12VDC from a cigarette lighter plug
and a DE-9 connector for connecting to a computer.
I bought it pretty cheaply last fall through a group buy from Garmin, but
there are units now that are much cheaper which are completely portable and
have display/keyboard/battery case built in. Check out the Garmin GPS-12XL
($250), Eagle Explorer ($199), or Lowrance Global Nav 200 ($250). All of
these are 12-channel parallel GPS receivers. If you're looking for a
remote-sensor type of GPS (like mine), you can get the DeLorme Tripmate
along with Street Atlas 4 for around $150. It's also a 12-channel receiver.
See my GPS page for an absolutely unwieldy list of GPS units and rough
prices I've seen in catalogs and on the net. Disclaimer: I am not in the
GPS business in any way. It's just a hobby. My web pages are entirely
non-commercial.
I am not using GPS on a robot. I'm only using the handyboard as an output
device for the GPS at the moment. GPS on a robot would require far more
money than reasonable for a hobby robot. In order to get any real accuracy
one would need survey-grade units that use both frequencies. Differential
GPS wouldn't even cut it for most uses.
Sci.geo.satellite-nav is the newsgroup for GPS discussion of all types.
