This is the library I am using:
https://github.com/jkua/ubx

Basically the only applicable files are ublox2.py and ubloxMessage.py.
There's some bug in how it handles its byte buffer and the buffer grows out
of control, which causes all sorts of issues. I tried to fix it but failed
due to time constraints. Highly recommend against touching that library...

I started off by using NMEA but found that there is was more resolution in
the UBX messages, so that's why I went that route. I thought there must be
a way to get the same resolution, but did not figure it out, and eventually
I had to just get it online so I could move on. Looking at gpsd, I'm still
not sure that it supports UBX, and I think that was why I disregarded it
before. Do you know if it does? The only UBX messages my project truly
needs are NAV-PVT and NAV-DOP, though I look at other ones for data
validation and debugging.
