Works for me. Are you sure your antenna is rated for Galileo?

Yes, that is Galileo enabled. You may need 30 minutes after enabling Galileo
to see any.

Looks good, except no Galileo.

GPS, but has a wider bandwidth than GPS. So the "better" antennas
that filter for GPS actually filter out Galileo.
