(C) Accuracy
This menu allows adjusting thresholds, where the vehicle shall be stopped.

When entering the code for the accuracy it is essential to pay attention to the type of
navigation system. The set value indicates the possible error the position may have:
If the vehicle is navigated with DGPS, the position is always available. If, e.g. an
accuracy of 0,05 meter is set, the vehicle will be stopped if the GPS outputs a
position accuracy of 0,07 meters.
If a transponder system is used, the position accuracy is determined differently.
Once a transponder has been crossed and the accuracy was good, the accuracy
is set to 0,01 meters. With each traveled meter, the accuracy decreases. E.g. if a
distance of 10 meters shall be allowed without Transponder reading, the value 0,5
meters (code 16) has to be set in the parameters. If 0,01 meters is set (code 15), 1
meter is allowed. If 0,02 meters is set, (code 14), 2 meters are allowed, with 0,03
meters set, the vehicle will be allowed to travel 3 meters etc.
For the sensor fusion, it is important that the accuracy is set to a value that allows
for one transponder to be missed, while the next one can still be reached safely.
At a transponder distance of e.g.
3 meters

7 meters travelling
