The device is quite amazing. Will use 30-40 satellites from a mix of GPS,
GLONASS, BEIDOU, QZSS (only on Windows, not on Android) and GALILEO. Is getting
signals from both L1 (1575MHz) and L5 (1176MHz) bands from most GALILEO and
half of BEIDOU and GPS, so removes most of the ionosphere noise.
One of the cross checks I do is to use a bidirectional Mapillary track
layer. I'd suggest fairly good for road centering in open places (ie no
phase delay GPS reflections). No good for non covered cross street
positioning of course.

Again, a recommendation to deal with imagery offset "smears:" start with the
"street network" (grid, whatever) first. That "lays down the meridians" as
accurately as you know with minimal effort right down to the centerlines of
multiple-lane tarmac. The small (er) stuff like buildings, those

Hi,
I’ve now got a relatively (<$100 + postage) Mouse GPS. It is amazingly
accurate. That’s the good news.
Now I can see a whole bunch of streets, buildings etc out by 1-5 meters as
*some* features were traced without correcting the image offset. Also found my
cheap GPS and an OSX machine are
