How is maximum coverage provided by satellites in the maritime satellite service?

Correct Answer: Option B — Four satellites in geo-stationary orbit approximately 22,184 miles above the equator.

Inmarsat provides near-global maritime coverage using four geostationary satellites positioned approximately 35,786 kilometers (22,184 miles) above the equator. These satellites remain fixed relative to the Earth's surface, allowing maritime terminals to maintain a constant link without the need for complex tracking systems required by low-earth orbit constellations.
