GMDSS. FCC Test 37

The process of logging out involves the following:

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

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

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

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

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).
Four satellites in polar orbit.
Through coordinated use of COSPAS-SARSAT satellites.

What is the primary function of a CES?

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.
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.

What is the primary function of an NCS?

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 do you determine that your Inmarsat-C terminal has accomplished a successful login?

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

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.
