the celluar sites are qualifed using GPS and then from there, the
system trangulates the positions of the users. There is no GPS
engine in the mobile phones themselves.
Quoted message said:I've been following this issue through the IEEE, and yes, there
is. The triangulation method is what it uses when there's no GPS
function in the phones, and is far less precise. If you're only
in range of one or two cell towers, triangulation is largely
useless, so they put the GPS functionality into the phones.
There are lots of places where a cell phone will work but GPS won't, so
they need triangulation as a backup.

That's the *whole* purpose of it in many areas.
That's the whole *official* purpose. It's really there so the gummint
knows where you are at all times, making it easier for the black
helicopters to find you.
