COG Source Values
The COG sensor provides information about
own ship course based on actual position
history (when a position sensor such as GPS is
providing the data). The COG folder lists the
available COG sensor data sources with the
currently active sensor source and its value in
highlight.
When Computed is selected for the sensor
data source for COG the system continually computes the values based on
other active types of sensor data received.
To change the COG sensor source or values do the following:
1. Tick the button next to the source. Whenever the sensor source is
about to be changed a window prompts you to confirm the change.
2. To confirm click the Yes button, or to return to the previous sensor
source and value click the No button.
If no sensor source is currently available the user can enter manual sensor
data.
CAUTION: MANUAL SENSOR DATA
Using manual data is not the normal mode of operation. A sensor
device should be selected as soon as valid data is available.
Manual data cannot be entered for COG if AIS input is enabled.
Before entering data turn off the AIS input, see AIS Display in
Chapter 10 `Targets’
1. To enter manual sensor data click in the MAN field, the text
changes to green (editable). Move the trackball left or right to enter
the required value and left click to exit edit mode.
2. Click the MAN button to enter the value.
3. When the sensor being selected for COG also provides other data
types (e.g. SOG or Position), a window appears prompting to select
which of these other data types should also be taken from manual
data, with the data type's current sensor source displayed. To
update all click the
Apply button, or untick the boxes next to the
data source where the update should not apply. To cancel all
changes and revert to the previous sensor source click
Cancel .
