How Does QFiled Reach Centimeter-Level Positioning Accuracy With T8 Pro Tablet?

When field tasks are required, Qfield, the mobile phone software of the QGIS series, is also often used for collecting GNSS data. With the development of GIS & GNSS industry, the requirements for the positioning accuracy of GIS tasks are getting higher and higher. Traditional sub-meter accuracy is not sufficient for some applications. So how can we achieve centimeter-level positioning accuracy in QFiled with mobile devices?

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.
