General GPS Question

[member kamituel]

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
GPS receiver and the satellite. This
distance is the radius of one sphere. When you combine signals from
three or fours satellites, you will get
three/four spheres, and the intersection point is your current location.
