Use of the GPS switch application
The reference point is the reference of the GPS signal to the
position of the field.
The reference point:
• must be set before saving a field / or use an existing one.
• should be calibrated when requested or if a deviation from the
terminal for the field has been detected.
The reference point:
• is the point on the field above which the GPS receiver on the
tractor is located.
• Must be approached using the tractor and recorded with the
vehicle at a standstill
• Serves to calibrate the location for the GPS signal.
• is an arbitrary point which can be found again. This point must
be on or in the immediate vicinity of the field to be tilled.
(e.g. drive until front tractor wheel makes contact with a border
stone).
• Must be noted for later work cycles when saving the field border.
Be careful and thorough when defining the reference point.
At each calibration, approach the reference point in the same way
from the same direction.
The existence of a correction signal is recommended for setting and
calibrating the reference point.
If a warning appears before an imprecise reference point do not set it.
If the position of the GPS antenna has changed after being refitted on
another tractor, the reference point must be reset.
→ In this case, calibration is not sufficient.
11.4.1 Incorrect calibration
Incorrectly calibrated data cannot be used.
Should you have inadvertently carried out a calibration at a wrong
location, it is possible to drive to the correct location and repeat the
calibration.
