Selection of the Position Sensor
1. Click on the position sensor area. The list of the
connected position sensors appears.
1)
2. Preselect the desired sensor by clicking. The position
received from this sensor, manually corrected if neces-
sary (for correction of a constant position-error, see page
62), is then displayed in the Multidisplay.
3. Furthermore, the bearing (BRG) and range (RNG) to the
position determined by the sensor that has been called up
are displayed in the Multidisplay.
Check whether the values displayed are plausible.
4. By clicking on the SELECT button, the sensor is selected.
☞ If a different sensor is to be preselected, this can be
done in the Multidisplay after clicking on the
displayed sensor.
☞ By clicking on the CANCEL button, the sensor previ-
ously selected remains selected.
Using Dead Reckoning to Determine the Position
If there is no position sensor available, or if the data from the position sensor are invalid or faulty, the
only remaining possibility of determining the position is the dead reckoning method, using the gyro
heading, the data from the selected speed sensor, and the drift value if such a value is entered.
WARNING:
The accuracy of the dead-reckoned position (display: EP) must be
checked continually. For safety reasons, an available position-sensor
must be selected as soon as possible.
The dead reckoning process is switched on in the same way as the selecting of a position sensor - see
above. During this process, the "position sensor" EP (= Estimated Position) must be selected. The special
feature is that, if EP is preselected, the starting position displayed in the Multidisplay can be changed.
The dead reckoning process begins with this position after pressing of the SELECT button.
Specifying the Use of the GPS Mode
If a DGPS receiver is selected, it can be specified whether the
received position is only to be used when the receiver is oper-
ating in differential mode.
Click on the MENU button, and then click on USER
SETTINGS.
If the position data of a DGPS receiver operating in GPS
mode (i.e. if differential mode is not possible) are not to be
used, the function DGPS ONLY must be switched on.
If the position data are to be used even when the differential mode has failed, the function DGPS ONLY
must be switched off.

If there are several sensors of the same type connected to the system, they are each given a sequential number in addition to the statement
of sensor type.
