ACTUAL Exam Questions and CORRECT
Answers
Which of the following actions should be taken once the vessel is berthed and will not leave port
again for several weeks? - CORRECT ANSWER - The GMDSS Radio Operator may log
out of the Inmarsat-C system and turn the power off (unless the vessel decides to leave the unit
on during the port stay.)
What action should always be taken before powering down an Inmarsat-C terminal or leaving
one satellite footprint for another? - CORRECT ANSWER - Log out with the current NCS
to inform them you are off the air or to enable a proper log in procedure with the new satellite.
With most Inmarsat-C systems what should the indicator lamps do when powering up? -
CORRECT ANSWER - All lamps should illuminate in a particular sequence, as per the
operator's manual.
What is the importance of a successful log in indication, after power-up, on an Inmarsat-C
terminal? - CORRECT ANSWER - The terminal is enabled for routine incoming and
outbound traffic.
On an Inmarsat-C system, what is the importance of a successful "SYNC" indication after power
up? - CORRECT ANSWER - Sufficient signal strength on the NCS common channel is
being received.
On an Inmarsat-C system an incoming EGC alarm sounds: - CORRECT ANSWER - To
draw the operator's attention to an unscheduled Distress or Urgency message.
Which satellite(s) would most likely be selected for use when the vessel is operating off the
eastern shore of the United States? - CORRECT ANSWER - AOR-W

Sea? - CORRECT ANSWER - POR

CORRECT ANSWER - 143.5 E
Which longitude corresponds to the IOR's satellite location for Inmarsat-C communications? -
CORRECT ANSWER - 25.0 E
Which action must be taken to ensure that incoming message traffic of all priority levels will be
received through Inmarsat-C? - CORRECT ANSWER - The GMDSS Radio Operator must
log-in to the desired satellite (if the unit did not automatically do so.)
When logging into the Inmarsat system using Inmarsat-C, it is necessary to: - CORRECT
ANSWER - Select the Ocean Region or select the NCS.
What action should be taken on changing from one Inmarsat-C ocean region to another? -
CORRECT ANSWER - Log out of the current satellite and log in to the correct satellite.
What is the primary danger of an Inmarsat-C terminal if it is not properly logged out? -
CORRECT ANSWER - Your company or another ship may accrue significant charges
when their traffic is repetitively sent to your unavailable terminal.
Which of these can take place on an Inmarsat-C terminal that has synch with the NCS CC but
has not yet performed a successful login? - CORRECT ANSWER - Reception of
unscheduled MSI Urgency and Distress messages.
