I should have mentioned that Google draws no data. Just some random NMEA logs,
user manuals telling you can turn PQXFI and PSTIS on/off with such and such

Ah... I have not noticed the xdop and ydop values until now. Cannot see
anything changing in unison with unknowns #1 and #2. I had assumed #3 was GDOP
or TDOP, but happened to carry the laptop outside yesterday and to my surprise
#3 plummeted to 0.03.
