Oh.. err.. sorry... i read that you would be modulating it onto a fiber
instead... Must be already half asleep ^^'

Yes, it would be possible. But you are not allowed to do it, because
you will be very strong GPS jammer. And don't count on the directivity
of antennas. They are not as directional as people think and the side
and back lobes will jam any receiver nearby
