Q

With an Inmarsat-C LES, how are messages routed to receiving stations?

🔍 Key Concepts

• Inmarsat-C is a digital, store-and-forward satellite messaging system (not a real-time voice circuit). • The role of a Land Earth Station (LES) is to interface between the satellite system and terrestrial networks (telex, email, etc.). • Difference between store-and-forward messaging and real-time connections/gateways.

💭 Think About

• Is Inmarsat-C primarily designed for continuous real-time communication, or for sending short digital messages that can be queued and delivered? • How would an LES typically handle many ships sending messages at once—does it set up individual live circuits, or process and forward messages through a messaging network? • Which choice best matches the idea that Inmarsat-C messages can be addressed to telex, email, and other shore-based services rather than directly to another ship’s terminal?

✅ Before You Answer

• Verify whether Inmarsat-C is described as a store-and-forward system in your GMDSS/Inmarsat study material. • Check if the LES is said to use message switching or circuit-switched (real-time) connections for Inmarsat-C. • Confirm whether the question is about how messages move through the shore-side network (after the satellite hop), not about how the ship terminal talks to the satellite itself.
