Switzerland?
Seems to me that Switzerland managed to negotiate access to Galileo and PRS in particular.

*If* it wanted to, the EU could confer on the UK a particular status, e.g. Trusted Ally, which would allow it to fully participate in Galileo and other sensitive EU projects.
I suspect that something like this will probably happen once the sabre rattling has ceased.
