🔍 Key Concepts

• Inmarsat ocean regions (AOR-E, AOR-W, IOR, POR) and what parts of the globe they cover • How longitude relates to where a geostationary satellite "sits" over the equator • Difference between E (east) and W (west) longitudes for identifying ocean regions

💭 Think About

• Which of these longitudes is roughly over the Pacific Ocean, not the Atlantic or Indian? • If you picture the globe, which given position would best serve ships in the Pacific Ocean Region (POR) for near-central coverage? • How do typical Atlantic (AOR-E / AOR-W) and Indian (IOR) satellite longitudes compare with those for the Pacific (POR) region?

✅ Before You Answer

• Be sure you know which oceans are under longitudes near 25°E, 54°W, 98°W, and 143.5°E • Confirm which longitudes are commonly associated with Atlantic vs Indian vs Pacific Inmarsat satellites • Eliminate any option that is clearly over Europe/Africa or mainly the Atlantic, not the central Pacific
