Look Ahead
The Look Ahead value is the number of seconds ahead of the vehicle you would like the SmartPad II software to cal-
culate the cross track error. Based on the vehicles speed and trajectory and this look ahead value, SmartPad II can
determine where the vehicle will be with respect to the current guideline. This setting will vary based on the vehicle
operators driving ability and preference. This value is only used with the guidance pattern Parallel. It is not used in
Headland curved guidance or the Circle Pivot pattern. A Look Ahead value that fits the operator best will result in
smoother guidance operations. Typically this value is set to 2 seconds.
To change the Look Ahead value; highlight the Look Ahead menu item and press . The Look Ahead dialog box
will appear. Enter the desired value using the arrow keys, , once the desired value is entered, press
to return back to the Guidance setup menu, see Figure 3-5
