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.

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
