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

Correct Answer: Option A — 64.5E

Inmarsat global coverage is divided into four ocean regions. The Indian Ocean Region (IOR) satellite is positioned at 64.5 degrees East longitude. This geostationary placement allows the satellite to provide essential GMDSS communication services to vessels operating within its designated footprint, ensuring reliable connectivity for distress and safety traffic.
