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
