As said, if the RMS values are not satisfactory then the user can, and he should,
proceed with the sensor calibration.
This operation is also suggested when the user changes the pole height and/or
the pole type (there could be a change in the straightness of the pole).
To calibrate the sensor, select the Calibrate page and then click on the
Calibrate Sensor command.
Follow the shown instructions to perform the calibration.
A Fixed GNSS solution is mandatory.
