Trimble FM-1000 - Antenna position and roll offset correction

14 TrueTracker setup Implement calibration for TrueTracker system
Antenna position and roll offset correction
Before configuring the antenna compensation, make sure that:
l TrueTracker is completely set up.
l The Autopilot system is properly configured. See Autopilot system (page 166).
l The correct GPS corrections are enabled. See GPS receiver settings (page 108).
1. At the Implement ControllerSetup screen, select Roll/Antenna Compensation and tapOK. The
Autopilot Roll/Antenna Compensation screen displays.
2.
Enter the appropriate settings and tap OK. Make sure the value entered for antenna height and
distance from centerline match those entered under Implement Geometry.
Setting Explanation
Antenna Height Above Ground
a. Place the tractor and implement on a flat, level surface.
b. Measure the distance from the ground to the base of
the GPS receiver (or antenna).
c. Enter this value in the Antenna Height Above Ground entry
box.
Antenna Distance from
centerline
a. Place the tractor and implement on a flat, level surface.
b. Measure the distance from the centerline of the
implement to the center of the GPS receiver (or
antenna).
c.
Enter this value into the Antenna Distance from centerline
entry box and indicate whether it is left or right of the
centerline.
Note –
Values to the left of the centerline are displayed as
negative numbers. The nose of the vehicle is considered the
forward direction.
Roll Offset
a. Choose the method that best matches the conditions
to calculate the roll offset:Coulter wheel track offset
method (page 288) or Flag offset method (page 289).
b. Enter the average offset value in the Roll Offset entry
box.
Implement Position Select the offline direction, depending on whether the roll
offset distance is to the left or right.
