GPS: Working! (well, nearly)

So I got my GPS module working.. sort of. After stuffing around with it for ages it turns out I was just being daft, and after fixing several obvious problems in both hardware and software I was getting lovely NMEA codes out:
The $GPGGA line is positioning data and the $GPGSV lines are data about the satellites we can see. Unfortunately from the flat we don't have enough sky view to be able to get a fix. The GPS is only tracking one satellite which is only good enough to give us the current time as shown in the first line (20:24:29).

Next plan is to write some software to do something useful with the data...
