Speed Sensor
There may be several speed sensors connected to the radar system. One of them has to be chosen. In
the case of speed sensors which transfer the longitudinal speed only, the drift and set can be entered
manually. As an alternative to selection of a speed sensor, it is also possible to input the speed manually,
if necessary. If fixed radar-targets are available, the speed can be determined by Reference Target
Tracking.
The speed sensors also include position sensors which transfer not only the position but also the
speed and course made good. Compared to the present-day state of the art, they generally do not
meet the IMO Performance Standards for SDME (Speed and Distance Measuring Equipment).
Therefore, they might not be configured in the system, and so it might not be possible to select them
for speed input.
Display of the Speed Data Used
In the SPD line, the speed data used in the system are
displayed: longitudinal speed, Bottom Track / Water Track
status, and the selected sensor.
 
If the longitudinal speed is computed taking account of
data that are entered manually (e.g. Set+Drift), the value
has a yellow background.
Selection of the Speed Sensor
1.
Click on the speed sensor area. The list of speed sensors
appears.
 1)
2.
Preselect the desired sensor by clicking. The data trans-
ferred from this sensor are then displayed in the Multidis-
play.
 2)
3.
Check the sensor data for plausibility.
Check the supplementary values which might be
suggested by the system (depending on the type of
sensor preselected - see below).
 3)
4.
The sensor is selected by clicking on the SELECT button.
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; values entered in
the Multidisplay are not taken over.
1)  
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.
2)  
The display indicating whether the speed displayed is over ground or through the water depends on the sensor:
-
COG/SOG or SPD + BOTTOM TRACK = speed over ground
-
 SPD + WATER TRACK = speed through the water.
3)  
The supplementary values suggested are computed by the system in such a way that, when they are taken over, no change occurs in the
longitudinal and transverse speeds.
