Which of the following describes the INMARSAT satellite system designations for AOR-E, AOR-W, POR, and IOR?

Inmarsat assigns geostationary satellites to regional groups with fixed longitudes to provide coverage over specific ocean areas. AOR-E and AOR-W are the Atlantic Ocean Region satellites (East and West), POR serves the Pacific Ocean Region, and IOR serves the Indian Ocean Region. The longitudes shown for these designations are the standard orbital slots used to maintain consistent coverage. The listed configuration—AOR-E at 15.5° W, AOR-W at 54° W, POR at 178° E, and IOR at 64.5° E—matches those established slots. This arrangement places the Atlantic satellites on opposite roughly western and central Atlantic longitudes, the Pacific satellite near the date line to cover the Pacific, and the Indian Ocean satellite in the eastern Indian Ocean, which aligns with how these regions are typically served. Other options propose longitude values that don’t correspond to the recognized Inmarsat regional slots, mixing up which satellite serves which region.
