Implement GPS Offsets
Press GPS OFFSET button on Implement Setup screen.
This button will only be active if an implement GPS
receiver is connected to the CAN Bus.
Enter Implement GPS Offsets:
IMPORTANT: Drive a vehicle forward and have
the vehicle & implement in a straight line
before measuring and calculating these
dimensions. This is very important for
accurate measurements.
IMPORTANT: Values must be accurate because
they will be used to calculate the track for
implement guidance and documentation.
NOTE: Minor adjustments to dimension B on the
Implement 1 GPS Offsets page can result in
measurable changes in offtrack error performance.
When modifying this value, minor increment
changes 1 cm (0.5 in.) is recommended.
There are certain value constraints to make iGuide work
refer to APPENDIX—VALID CONFIGURATION.

GPS Offsets
A—Inline distance from
connection point to GPS
receiver.
B—Lateral distance from
implement center to GPS
receiver.
C—Vertical distance from GPS
receiver to ground with
implement engaged.
D—Lateral offset toggle button
E—Verify implement fore/aft
and offsets in the StarFire
setup pages.
Measuring in line dimension from receiver
to receiver
Measure the distance between the vehicle receiver to
the implement receiver and then compare to the total
of dimensions "B" and "C" from Machine Offsets Page
(section 155), and dimension "A" from the Implement
GPS Offsets Page (section 15 10). The physical distance
between the receivers should match the distance found in
adding these three dimensions.
Example:
Distance between vehicle and implement receivers =
255 inches
Dimensions "B" in Vehicle offset page = 55, "C" in
Vehicle offset page = 65, and "A" in Implement receiver
offset page = 135 in. In total equaling, 255 inches.
NOTE: Measure from middle of vehicle receiver to
middle of implement receiver.
NOTE: For articulated tractors, the distance from
receiver to connection point is B subtracted from
C. (i.e. distance = "C" "B" + "A")
