After only a few hours, some awesome people from OSM already improved my changes. Awesome!

Which SXBlue model were you using? Any details on how you're able to get RTK corrections without a base station? Or was the SXBlue fusing together data from GPS and GLONASS to obtain centimeter level positioning?

SXBlue III.

The SXBlue unit was fusing GPS and GLONASS, but in addition, there are lists of public stations that anybody can tap to.
