High-Precision GNSS/RTK Settings (KB-GI009)
Setup
vGIS supports external GNSS and RTK devices for added precision. Jobs that typically require high-precision hardware include high-accuracy work with survey-grade data, inspections of long pipelines and precision construction.
First, you'll need to enable a high-precision GNSS/RTK device by connecting it to your phone or tablet using the Bluetooth or cable and, in case of some devices, running a separate background app.
Enabling GNSS in vGIS AR
First, Tap the Menu button.
Enable the GNSS button, then Tap Options.
The GNSS tab should be open by default. In the Positioning Mode line, selections vary from a catalogue of GNSS suppliers (or other external Bluetooth devices), the vGIS External Mock Mode, or Internal Compass/ GPS positioning. (Fig. 3)
When the selection is made, Close the menu to save changes.
