If an Inmarsat Distress Alert Setup menu contains an incorrect or unavailable LES code what happens to the Distress Alert transmission?

🔍 Key Concepts

• Inmarsat ship earth station (SES) distress alerting flow (ship → LES → NCS → RCC) • Role and limitations of the Network Coordination Station (NCS) in routing messages • What happens when an LES code or ocean region selection is wrong or not available

💭 Think About

• Think through the normal path a distress alert takes from the ship to the rescue coordination center (RCC). Which stations are involved, and in what order? • Ask yourself: does the NCS actively "fix" bad setup data from a ship terminal, or does it mainly manage network resources and channel assignments? • Consider what happens if you dial a non‑existent or wrong number on a telephone. Does the network correct it for you, warn you, or simply fail to connect? Which of the choices most closely matches that behavior for Inmarsat distress alerts?

✅ Before You Answer

• Verify the defined responsibilities of the Network Coordination Station (NCS) versus the Land Earth Station (LES) in GMDSS/Inmarsat documentation. • Check whether any equipment or shore station is required to automatically update the ship’s LES codes as it moves between ocean regions. • Confirm what the exam syllabus says happens to a distress alert when it is addressed to an incorrect or unavailable LES code—does it get rerouted, rejected with an alarm, or simply not received by an RCC?

If an Inmarsat Distress Alert Setup menu contains an incorrect or unavailable LES code what happens to the Distress Alert transmission?

The NCS updates the LES codes in the Distress Alert Setup menu as the vessel moves from ocean region to ocean region to ensure this does not happen.

The NCS will send a Distress Alert Setup incorrect LES code alarm so the alert can be corrected and re- transmitted.

The NCS will step in and route the Distress Alert transmission to an RCC.

If the LES code is incorrect then the Distress Alert transmission is not detected by any RCC.
