🔍 Key Concepts

• Inmarsat ocean regions (AOR-E, AOR-W, IOR, POR) and their approximate coverage areas • Relationship between satellite longitude and the ocean region it serves (Indian vs Atlantic vs Pacific) • How east and west longitudes correspond to Indian Ocean, Atlantic Ocean, and Pacific Ocean positions on a world map

💭 Think About

• First, visualize or sketch a simple world map and mark the rough longitude bands for the Atlantic, Indian, and Pacific Oceans. Which longitudes are over the Indian Ocean? • Identify which answer choices clearly fall over the Atlantic or Pacific, then eliminate them. Which one(s) remain as plausible for the Indian Ocean Region (IOR)? • Think about the naming: Indian Ocean Region (IOR). Which longitudes would place a geostationary satellite above the Indian Ocean so it can cover that region effectively?

✅ Before You Answer

• Be sure you know roughly which longitudes correspond to Atlantic, Indian, and Pacific Oceans before choosing. • Double-check which choice(s) are clearly over the western hemisphere (W longitudes) and whether those are consistent with the Indian Ocean Region. • Confirm that the option you select places the satellite above a longitude that would actually be over or near the Indian Ocean, not a different ocean.
