How about syncing them at one physical place, moving while powered using a battery, then hot-deploy in target datacenter?

  Pretty sure relativity limits the usefulness of this. http://www.astronomy.ohio-state.edu/~pogge/Ast162/Unit5/gps.html http://www.astronomy.ohio-state.edu/~pogge/Ast162/Unit5/gps....

    It's rather amazing that anyone with a couple of atomic clocks can see the effects of relativity themselves: http://leapsecond.com/great2005/ http://leapsecond.com/great2005/

    > Relativity is not just some abstract mathematical theory: understanding it is absolutely essential for our global navigation system to work properly! I wonder if we could get away by just building it and accounting for the error using some multiplier, without understanding the concept of relativity. I.e., how we would build it if we invented satellites before relativity.
