Re: end UK dependance on GPS?

If you also have accurate accelerometers you could dead reckon.

You would still need the occasional* reference, perhaps from land based systems

*how occasional depends on the accuracy of your clock and accelerometers.

I believe inertial navigation is still one input to commercial aircraft navigation systems
