"by the time Galileo is up and running we will likely be trying to get back into the EU anyway."
I'm not sure that that is such a good idea, overall.
Sure, it would be good for the UK, but not so much for the EU.
Historically the UK has been an obstructionist force and a drag on the evolution of the EU into one of the 21st century's superpowers. They're better off without the UK.
