5 Connect with GIS Software

The Sfaira ONE receiver is very suitable for GIS measurement. Compared to ordinary receivers, it

has smaller size, lighter weight, and retains powerful performance. If you want to use Sfaira ONE

and other GIS software for measurement, please follow the following steps. Let's take Qfield as an

example.

First, you should connect Sfaira ONE with SingularPad, and setup it to get a fixed solution.

Second, In the software setting, enable the location services, it will share the high precision

positioning data to the controller.

Go to the system settings of your controller, click the system version 5 times to open the developer

option. In the developer option, there is a function Select mock location app, this function will use

the position from the app as the position of controller, and you should select SingularPad.

After that, you can go to Qfield, choose the Positioning Device as internal device, it will use the

position of the controller which is RTK fixed position from the Sfaira one.

Then you can do your GIS work.
