🔍 Key Concepts

• Line-of-sight requirement between Inmarsat satellite and ship earth station (SES) antenna • Effect of obstacles and vessel heading on satellite antenna performance • Inmarsat system limits: geostationary orbit coverage and elevation angles

💭 Think About

• For each option, ask: Would this physically prevent the SES antenna from ‘seeing’ the satellite, or just make the signal weaker? • Consider how geostationary satellites are positioned over the equator. What happens to the elevation angle and coverage area as you move toward the poles or far from the satellite’s designated region? • Think about whether more than one of these conditions could occur in real operations and whether they are independent causes of total loss of communication.

✅ Before You Answer

• For each choice, decide if the satellite is still above the radio horizon of the antenna or not. • Check whether an obstruction tied to ship’s own structure and heading can completely block the antenna’s view of the satellite. • Recall that Inmarsat geostationary satellites have a limited coverage footprint and minimum usable elevation angle—verify how that could make communications impossible.

Question 1 of 20

Which of the following conditions can render INMARSAT -B communications impossible?

An obstruction, such as a mast, causing disruption of the signal between the satellite and the SES antenna when the vessel is steering a certain course.

A satellite whose signal is on a low elevation, below the horizon.

Travel beyond the effective radius of the satellite.

All of these.
