Galileo has been enabled using the ubx-center program as has NME 4.1, 
and the Galileo satellites are present. Nmea sentences as monitored by 
ublox-center are present

I also disabled all constellations except Galileo, but suspect using gpsmon 
this may be modified by gpsd as there are more satellites that I expect, and 
the GNSS constellation
setting as shown by ublox-center show gps/glonass enabled

Grepping the code show’s no occurrences of $GAGSA or $GAGSV sentences,
which makes me suspect gpsd is not Galileo compliant, but I am happy to be 
proven incorrect :)

Anyone got any ideas on this?
