Precision Settings
The Precision Settings screen enables the user to set the correction source and to enable Flex Mode for AutoSteering. Flex
Mode provides continuity of position solution to maintain automated steering by seamlessly flexing (transitioning) to a lower
accuracy mode when a higher accuracy mode is lost; such as loss of the RTK radio link.
For example, if a large group of trees or buildings come between the vehicle and the Base Station, the GeoSteer may
temporarily lose the RTK data signal. The flex mode enables the system to flex back to a lower accuracy mode (WAAS,
EGNOSE, Autonomous Pass-to-Pass) without the loss of AutoSteering. The system continues to attempt to achieve position
with the best available mode and automatically transitions to the next best mode. The transition is seamless. Reverting to a
better mode is automatic and instantaneous if the system is not actively steering. If the system is actively steering when a better
GPS position is restored, the system gradually shifts to higher accuracy mode.
Note: Slight position jumps are possible, though rare, whenever switching between modes.
