5.4.3 RECEPTION AN A AIS-SART COMPLIANT AIS TRANSPONDER:
The requirement to have a AIS-SART compliant AIS transponder, is not ready
yet, not when it will be implemented, nor what the final requirement will be. But
there are drafts of new AIS specification, IEC 61993-2 (Ed.2) which states:
By default the target list is auto-sorted in ascending range except the nearest
active AIS SART or, if supported, other target of interest shall be displayed at
the top of the list.
In addition, there will be possibly automatic filtering of AIS SART’s in TEST since
the test will send text messages to all nearby ships (within VHF range). There
are today two suggestions on how to implement the filtering:
1. Prior to test the AIS-SART on your own ship, you must enter “Configuration
menu” of your own AIS transponder, and turn on “Show AIS-SART Test”
2. Only receive AIS-SART in “Test” within a very limited range
- will be possibly be shown with the text “SART TEST” as “vessel name” with
range, bearing and position:
- In addition, a text message will be received:
5.4.3 RECEPTION AN A AIS-SART COMPLIANT ELECTRONIC CHART
(ECS/ECDIS):
Even though the AIS transponder is not AIS-SART compliant, the electronic
chart may show the correct symbol when receiving an AIS-SART in “Test” or
“Active” if it is updated to the latest revisions defined below:
- will be shown with this special symbol as defined here:
SN.1/Circ.243/Add.1 and in lates revision of IEC 62388:
- An AIS Search And Rescue Transponder (SART) shall be presented as a circle
with an “X” inscribed inside it. The circle shall be 5 millimetres in diameter. The
symbol shall be drawn using a thick dashed line style with the colour red. The sym
bol shall flash until acknowledged by the user.Once acknowledged, the symbol
shall cease flashing.
- with the same text message received:
