Filter Settings
Filter Settings enables different types of AIS targets and AIS NAV symbols
to be displayed (ticked) or not displayed (unticked).
The system prioritises AIS targets into class A and class B vessels. The
distinction is made based on the type of message received via the AIS
transponder installed on the originating vessel. For a description of class A
and class B targets see `Classes and Types of AIS.
 Class A - only class A targets are displayed (default setting).
 Class B - only class B targets are displayed.
Filter settings will only remove sleeping targets from the screen. Selected
and activated class A and B targets will continue to be displayed.
Filter settings also enables the display of the following AIS Nav Symbols (if
enabled in the system):
 Physical ATON - will display Aid to Navigation objects
 Virtual ATON – will display virtual AtoNs with GPS co-ordinates
 Base Station - will display Base Station objects
 SAR Aircraft - will display Search and Rescue Aircraft
 AIS-SART - will display AIS Search and Rescue Transponders
 MOB - will display Man Over Board event
 EPRIB - will display Emergency Position Indicating Radio Beacons
For a more detailed description of the AIS types listed above refer to
`Classes and Types of AIS’.
If any filter settings are switched off, the AIS button on the upper toolbar is
displayed with an additional AIS icon in white outline, see AIS Input and
Filter Button.
If the operator attempts to untick the Class A or
Class B check boxes when the Activate on
CPA/TCPA/BCR setting is disabled an `Action
Required’ prompt appears informing that filtering
out the deselected class will automatically enable
Auto-Activation.
To proceed with target filtering click the Yes
button. The sleeping targets for the selected filter
class are removed from the screen and Activate
on CPA/TCPA/BCR is enabled.
