🔍 Key Concepts

• Line-of-sight satellite communication between ship earth station (SES) antenna and the satellite • Effects of physical obstructions and elevation angle on satellite links • How weather and distance from the satellite’s coverage area can affect signal quality

💭 Think About

• Which of these options would completely or almost completely stop the SES antenna from "seeing" the satellite, instead of only weakening the signal? • Think about how Inmarsat-FBB is designed for ocean-going ships: which type of common environmental condition would the system be engineered to tolerate reasonably well? • Which condition describes a situation where the satellite is no longer in a usable position or coverage area for that ship?

✅ Before You Answer

• For each option, ask: does this cause loss of line of sight between antenna and satellite, or just signal attenuation (weakening)? • Recall that Inmarsat systems are designed with some rain fade margin—how does that relate to "normal" gales and storms? • Consider the meaning of satellite elevation and coverage radius (footprint) and how moving outside that footprint or below the horizon affects communications.

Which of the following conditions does not typically impair Inmarsat-FBB communications?

An obstruction, such as a mast, blocking the signal between the satellite and the SES antenna when the vessel is steering a specific course.

Normal precipitation from gales and storms .

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

Travel beyond the effective radius of the satellite.
