Official USCG Answer & Rule Citation
Correct Answer: Option D — 54W
The AOR-W (Atlantic Ocean Region-West) satellite is positioned at 54 degrees West longitude. This specific orbital slot is critical for GMDSS operators to know, as it allows for the correct manual configuration of the terminal's satellite selection, ensuring the equipment locks onto the appropriate satellite for the vessel's current geographic location.
