GMDSS. FCC Test 37 – Online Maritime Tests

What is the primary function of a CES?

To provide multi-mode communications between the Inmarsat station placing a call and the coast radio station that will deliver it.
To monitor and control communications through the Inmarsat satellite for which it is responsible.
To determine which satellite is best suited to provide communications between the Inmarsat station placing a call and the station receiving the call.
To provide direct communications between the Inmarsat station placing a call and the station receiving the call.

How is maximum coverage provided by satellites in the maritime satellite service?

Four satellites in polar orbit.
Four satellites in geo-stationary orbit approximately 22,184 miles above the equator.
Four satellites in geo-stationary orbit for each Inmarsat Service (A, B, C and M).
Through coordinated use of COSPAS-SARSAT satellites.

What is the primary function of an NCS?

To determine which satellite is best suited to provide communications between the Inmarsat station placing a call and the station receiving the call.
To provide multi-mode communications between the Inmarsat station placing a call and the coast radio station that will deliver it.

What action should be taken on changing from one ocean region to another?

The process of logging out involves the following:

When logging into the Inmarsat system using Inmarsat-C, it is necessary to:

Select the Ocean Region.
Enter the CES answer back.
Call the CES and inform them that you are now operating in the appropriate ocean region.
Enter your IMN.

Which action must be taken to ensure that incoming message traffic of all priority levels will be received through Inmarsat-C?

No additional action is necessary after turning on the receiver and aiming the antenna at the desired satellite.
The system needs only to be commissioned and turned on.
The GMDSS Radio Operator must log-in to the desired satellite.
The GMDSS Radio Operator must log on to the desired satellite and receive the message reference number (MRN) from the CES.

On many Inmarsat-C terminals, which of the following indicates a successful log-in?
