GPS MEASUREMENTS
To provide accurate guidance during field operations, calibrate the ROS for the position of the GPS antenna on the
machine relative to the center of the pivot point. Refer to the following sections for assistance with measuring and
setting the GPS measurements on the ROS device.
NOTE: The pivot point for a conventional tractor or self-propelled sprayer is the center of the rear axle.
The pivot point for a tracked tractor is the center of the track length between the tracks.
The pivot point for an articulated tractor is the point of articulation.
Left/Right Offset Direction. Touch the left/right offset direction drop down and select the position of the
GPS antenna from the center-line of the machine.
Left/Right Offset Distance. Select the GPS offset distance field and enter the distance from the center-
line of the machine to the GPS antenna in inches [centimeters]. The left/right offset distance must be measured
perpendicular to the direction of travel.
Fore/Aft Offset Direction. Touch the fore/aft offset direction drop down and select the position of the
GPS antenna from the machine pivot point.
Fore/Aft Offset Distance. Select the GPS offset distance field and enter the distance from the pivot point
to the GPS antenna in inches [centimeters]. The fore/aft offset distance must be measured parallel with the
direction of travel.
GPS Antenna Height. The GPS Height value is the measurement from the ground to the bottom of the GPS
antenna. The height value will only be necessary if a tilt corrected DGPS signal is provided to the field
computer.
MACHINE AND HITCH MEASUREMENTS
The machine measurement settings provide information about the machine geometry used by ROS to map the
vehicle position during field operations and create coverage or as-applied data for field operations.
Hitch Left/Right Offset Direction. Touch the left/right offset direction drop down and select the position of the
machine hitch from the center-line of the machine.
Hitch Left/Right Offset Distance. Select the offset distance field and enter the distance from the center-line of
the machine to the hitch in inches [centimeters]. Measure the left/right offset distance perpendicular to the
direction of travel.
Hitch Fore/Aft Offset Direction. Touch the fore/aft offset direction drop down and select the position of the hitch
from the machine pivot point.
Hitch Fore/Aft Offset Distance. Select the offset distance field and enter the distance from the pivot point to the
hitch in inches [centimeters]. The fore/aft offset distance must be measured parallel with the direction of travel.
Wheel Base. The wheel base value is used by ROS to map coverage of the implement during field operations.
Enter the distance between the front and rear “axle” in inches [centimeters]. The wheel base must be measured
parallel with the direction of travel.
Pivot to Front Axle. For articulated vehicles, measure the distance from the pivot point to the front axle.
Pivot to Rear Axle. For articulated vehicles, measure the distance from the pivot point to the rear axle.
