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.
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.
