| Hello all,
Can anyone recommend the best unit out there for "uncharted"
terrotories? I am looking to use it in the desert to bascially find
base camps and in case search and rescue need to find the team.
Also I heard of units that can be tracked from the office to find out
where the vehicles are at all times.

Any basic GPS. If there are no maps of the area, then you don't need a
mapping unit. The Garmin yellow eTrex would work fine for you, as well
as the comparable Magellan.
If you want tracking, then you will need a satellite phone attached to
the GPS. A GPS is a receiver only, and in order to track it you have to
have a transmitter, which can be received by something else. Cell phones
can do the job, if you can be assured of receiving a signal from a cell
tower. Otherwise, you'll need to use a satellite.

I second the basic yellow etrex - it's an excellent device. In my
experience even an old yellow model works better than the higher spec and
much more expensive monochrome versions of the etrex, if you are not
interested in the mapping features. However if you decide on one of these
be aware that there is a completely new version filtering onto the market
with enhanced features (including WAAS/EGNOS capability and improved data
display features) so make sure you know which version you are getting before
handing over your cash.

Agreed. Decide what all of your uses are. I needed/wanted one that I
didn't have to be in motion for the magnetic compass to function,
provided auto-routing for trips, WAAS, color, marine charting, and long
battery life. The only unit that satisified my requirements was the
Garmin GPSMap 76CS but YMMV. Do your homework based upon your
requirements.

Of course, but it does require a complete system, and many systems simply
don't have the range required. Anything other than HF will be limited to
line of sight, which may not be sufficient. HF is problematic, WRT power
requirements, antenna size, frequency propagation, and other stuff.
Unless you're working at very close ranges, radio simply won't do the
job. However, at short range, it might be the best solution. Depends.

I work for a bus company that uses GPS to track the position of buses to
display the estimated arrival time at stops, also so the office can check
where they are. The buses each have a GPS receiver and this is linked to
the company radio system which is trunked and uses several base stations
on approx. 200 MHz. It usually works ok, although like any system it falls
over occasionally.

A bus is certainly large enough to hold an HF radio, and it should work
fine for short distances, such as within a city, especially with a number
of repeaters available. I didn't understand that the OP wanted to use it
on busses, though. ;-)
