They can take quite a while to get a lock (ublox) so a window or outdoors is recommended. Or an AGPS setup, of which I cannot remember anything about to get the location of says.
Lots of commas is a lock problem normally.
You can double check using
cat /dev/serial0
And see what it is actually providing.
Or gpsmon
May need to use
gpsmon /dev/serial0
Gpsmon can actually use the ublox 'speak' directly, you get lots of funny characters.
If I get time I'll pop the gpsd methods too, but it has been a while. There are some floating around on the forum.
Gpsd had the advantage that it is always working, you can read it from another device over the network (run python on a phone/pc/another pi and read it from the Pi) etc..
