Antenna Fore/Aft
The Antenna Fore/Aft measurement is the distance the GeoDock GPS antenna is attached to the vehicle as compared to the
Pivot Point of the vehicle. The Pivot Point of the vehicle is the place where the vehicle rotates around as it turns left or right.
The location of the Pivot Point is different depending on what vehicle type is being installed on. Common Pivot Points for
most vehicles are:
•
Front Axle Steering – The Pivot Point is at the rear axle for MFWD, SPRAYER, FLOATER vehicle
profiles.
• Track
Vehicle – The Pivot Point is at the center point of the track.
• Articulated
Vehicles – The Pivot Point is at the articulation joint of the vehicle.
•
Rear Axle Steering – The Pivot Point is at the front axle for COMBINE and SWATHER vehicle
profiles.
First identify the Pivot Point on the vehicle that the GeoSteer is being installed on. Take a tape measure and measure the
distance between the Pivot Point and the GPS antenna on the GeoDock. Enter that value into the Antenna Fore/Aft window.
Note: Be sure to verify that the measurement entered is in the same units that the display is expecting. The expected unit of
measurement is shown to the right of the data input box.
Note: The units of measure shown in the AutoSteer Setup pages are configured on the Display side and passed to the GeoSteer
menus. Refer to your Display Operator’s Manual for instructions on how to set the units of measure.
