🔍 Key Concepts

• Iridium system architecture – how ships, satellites, and shore stations are interconnected • Difference between ship earth station (SES), satellite, and land earth station (LES) roles • How a call or data message travels from a ship’s terminal to a shore-based phone or network

💭 Think About

• Trace the signal path: when a ship uses Iridium to call a shore telephone, what are the steps from the handset/terminal all the way to the person on land? Where does the LES fit in that chain? • Consider which option sounds like it describes the satellite’s job versus what a ground station on land would actually do. • Look for the choice that best describes a shore-based gateway function, not distress-only and not ship-to-ship-only work.

✅ Before You Answer

• Verify which entity actually connects the satellite network into terrestrial phone/data networks (PSTN, internet). • Check whether the LES’s role is limited only to distress traffic or whether it supports routine communications as well. • Confirm that Iridium does not require a separate Inmarsat LES for ship-ship calls, since Iridium is a different satellite system.

Question 1 of 20

What is the primary purpose of an Iridium LES?

The LES is required for ship-ship Inmarsat communications, ship-shore communications are handled by terrestrial Coast Radio Stations.

The LES monitors all operations of the satellite and assigns channels and frequencies to the vessel.

The LES makes the satellite connection between the vessel and the requested shore destination .

The LES is dedicated only to processing all vessel Distress priority calls.
