Seriously, altimeter chips have been mentioned on this list in the
past, when proposals have been made for including an altimeter. But an
altimeter is unlikely to reach a production Openmoko phone because the
demand is too small.
I wasn't proposing that
Shouldn't it be possible to get the own position from three signals from the
same satellite?
The result would not be as exactly as from three or more but even better then
no result.
Why should it not work?

No, because GPS run calculation triangulation from the
You can only get current time from one satellite. It is not possible
to compute your current position.
It would be possible, though, to find out what is the distance between

distance is the radius of one sphere. When you combine signals from

The satellites are moving around. So on a different time the position is
different.

There is a number called the dilution of precision which quantifies
the factor by which the accuracy of the GPS reading is reduced

First the satellites are not moving fast enough, and they are moving in
the same direction of course, so you cannot really do triangulation (the
