AIS - Automatic Identication System | NSO-II Operator Manual
If you have enabled the siren, the alarm message will be followed by an audible alarm.
The following section describes the options available when an AIS SART message is
received by a Navico NAIS-400 transponder.
AIS SART alarm message
When data is received from an AIS SART, an alarm message is displayed on the NSO-II .
This message includes the AIS SART’s unique MMSI number, its position and its distance
and bearing from your vessel. You have three options:
1. Ignore the alarm
- The alarm is muted and the message closed. The alarm will not reappear
¼ Note: If you ignore the alarm, the AIS SART icon remains visible on your chart, and the AIS
SART remains in the Vessels list.
If the AIS stops receiving the AIS SART message, the AIS SART remains in the Vessels list
for 10 minutes after it receives the last signal.
2. Save the waypoint
- The waypoint is saved to your waypoint list. This waypoint name will be prexed with
MOB AIS SART - followed by the unique MMSI number of the SART. e.g. MOB AIS SART
- 12345678.
3. Activate the MOB function
- The display switches to a zoomed chart panel, centered on the AIS SART position
- The NSO-II creates an active route to the AIS SART position
¼ Note: If the MOB function is already active, this will be terminated and replaced by the
new route towards the AIS SART position!
If you select the AIS SART icon on the chart you will see the AIS MOB details.
