Re: end UK dependance on GPS?

But how does your device know the distance to each satellite?

If only there was something that could be measured that when combined with an initial location (i.e. latitude/longitude/altitude) and a known speed (close enough to the speed of light plus some adjustments for atmospheric effects) that would allow you to work out distance.
