🔍 Key Concepts

• INMARSAT ocean regions: Atlantic Ocean Region East/West (AOR-E, AOR-W), Pacific Ocean Region (POR), Indian Ocean Region (IOR) • Typical geostationary satellite positions in degrees longitude over the equator • Difference between E (East) / W (West) labels and how they match ocean basins

💭 Think About

• Which combination of longitudes places the AOR satellites over the Atlantic, the POR satellite over the Pacific, and the IOR satellite over the Indian Ocean? Visualize a simple world map with 0° at Greenwich. • Do any options show duplicate or very close longitudes that would not reasonably cover separate ocean regions? • Check whether any choice incorrectly splits or duplicates an ocean region (e.g., extra POR or extra IOR) compared to the standard four-region layout.

✅ Before You Answer

• Verify that AOR-E and AOR-W both lie over the Atlantic (on either side of 0°) and are not placed over the Pacific or Indian Oceans. • Verify that POR has a longitude consistent with the central Pacific, far from 0° and clearly in the Pacific basin. • Verify that IOR has a longitude that clearly falls over the Indian Ocean, between Africa and Australia.
