it is not gps it is triangulation through cell towers.

it basically works the same way as GPS but on the ground

in essence your cell talks to the towers on a constant
basis. At any time it is talking to several towers.

let's assume you can see 3 towers (there could be more
and the more there are the more precise the pin point)
call them A, B and C and we draw their respective areas.
Like this venne diagram



if C and A receive your transmission but B does not,
then you are in area 6. It also has the advantage that
a cell tower (like your phone) can determine strength.
so if C is receiving a stronger signal then A you know
it is closer to C then A.

The weakness is that the signals are not even like the
venne diagram. On the other hand you tend to be “touching”
more then three towers.

lol ..never thought a serious answer would be so funny!!
