Some do, some don't.  I think Nextel uses real GPS receivers.  My Motorola
phone's got 'assisted GPS', which means it relies on the base station (as I
understand it) to tell it where to listen, and to interpret what it hears.
Basically you're separating the GPS receiver's RF stuff from the processing
engine, and linking the two by cell phone.

You mentioned in a previous e-mail that many newer cell phones are GPS
enabled.  However, they do not actually have GPS recievers in them.  The
location of the phone is determined based on signal strength and direction
from cell towers and triangulation...  There is no direct reception of
satellite GPS signals by the phone itself.  Just FYI.

I find it hard to believe that Icom can come up with the whole D-Star system

but can't put a GPS receiver in an H/T. Does anyone see the point of 2 meter

digital voice? As far as I can tell most 2 meter repeaters are hardly used
anymore as it is.
