There are commercial "re-radiators" for GPS. I found these on Google:

Things may have changed as this was a few years ago.

By the way, would it be possible to retransmit the GPS signal to isolate it? I mean, rx external antenna -> preamp -> tx directional internal antenna -> big air gap -> rx directional internal antenna -> receiver. The preamp would not be so power hungry as the full thunderbolt and maybe it could be powered via a magnetic link (or a little solar panel with a lamp illuminating it).
