end UK dependance on GPS?
A very small atomic clock will be a significant technical achievement but I can't see how it provides a means of navigation or removes the need for GPS.
It could be part of a navigation system as atomic clocks already ready are in satellite navigation systems. On the face of it this is just hype based on the first thing that has any connection to precision time keeping, or I am being very stupid and there is someway that a really accurate time source provides position without the need for signals from satellites, measuring the position of astronomical objects etc.
The hype seems to originate from the University of Sussex or the researchers as it is not just in the register.
