Which longitude corresponds to the POR's satellite location for Inmarsat-B/C communications?

Correct Answer: Option B — 178E

The POR (Pacific Ocean Region) satellite is positioned at 178 degrees East longitude. This satellite provides the necessary coverage for the vast Pacific basin. Operators must select this satellite when navigating in the Pacific to ensure the Inmarsat-C terminal can successfully log into the network and receive critical maritime safety information.
