How does QFiled reach centimeter-level positioning accuracy with T8 Pro tablet?

For many in the GIS industry, QGIS is a very familiar desktop tool for editing and analyzing geospatial data. When field tasks are required, Qfield, the mobile phone software of the same series, is also often used for collecting GNSS data.

About QField
