🔍 Key Concepts

• Geostationary orbit vs polar orbit and how each affects coverage at sea • The typical altitude of geostationary satellites used for global communications • Difference between Inmarsat (maritime comms) and COSPAS-SARSAT (distress alerting/search and rescue) systems

💭 Think About

• Ask yourself which orbit type allows a satellite to appear fixed over one point on Earth, making it easier for ships’ antennas to stay pointed at it. • Consider what approximate altitude is commonly associated with geostationary communications satellites. • Think about whether Inmarsat relies on its own communications satellites or on the COSPAS-SARSAT distress system for maximum routine communications coverage.

✅ Before You Answer

• Verify which choice correctly describes geostationary orbit above the equator (both orbit type and rough altitude). • Eliminate any option that uses polar orbit, since that is not how Inmarsat’s primary comms satellites are deployed. • Confirm that COSPAS-SARSAT is a separate SAR/distress alert system, not the main Inmarsat communications constellation.

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

Four satellites in polar orbit to provide worldwide coverage.

Four satellites in geo-stationary orbit for each Inmarsat Service (C and FBB).

Four satellites in geo-stationary orbit approximately 22 , 184 miles above the equator .
