MARINE MOBILE SERVICE IDENTITY
(MMSI)
the mmsi is a 9-digit number used to identify a radio that is
capable of using Digital selective calling (Dsc). the number
is used to selectively call other vessels. to setup and use the
Dsc feature on your radio: Please refer to the ‘Dsc’ section of
this manual.
uSeR MMSi
to use the Dsc feature you must be registered with the
appropriate licensing authority (amsa in australia) who
will issue you with your unique user mmsi number. having
a registered user mmsi means you can be identified much
quicker in an emergency. once you have obtained your mmsi
number you can then enter this into your GX850 to enable
Dsc operation. Your GX850 is shipped from the factory
without a user mmsi number. it is up to the user to obtain a
valid mmsi from the appropriate licensing authority.
note:
if you don’t register for a user mmsi, you can still
receive Dsc distress calls from other vessels however you
cannot send a Dsc call.
GRouP MMSi
the Group mmsi is used for Dsc Group calls. a Group call
provides a method for contacting a group of vessels with a
common interest, for example, alerting all yachts in a race to
announce a change in the race conditions. any number with
a leading zero can be used as a Group mmsi, and they do
not need to be registered, but the entity deciding on a Group
mmsi must use the miD of the host country or country of
vessel registration (e.g. 503 in australia). the Group iD should
be based on a key vessel in the Group, and the recommended
system is to drop the last digit of the key vessel’s mmsi and
place a zero in front.
For example, a fleet of vessels that has a lead vessel with a
Dsc user mmsi of 503080110 could use the Group mmsi
of 050308011. this would then be programmed into all fleet
vessels as the special event Group mmsi.
see ‘my mmsi iD setup’ on page 13 for details on entering
a group mmsi.
