What statement is true regarding LES codes...

🔍 Key Concepts

• LES (Land Earth Station) codes are tied to specific coast earth stations and sometimes to specific services, not just to satellites or NAVAREAs • Inmarsat GMDSS “hot-key” distress/urgency/safety menus are pre-programmed with contact options that depend on which LES you are logged in to • Responsibility for updating LES selection relates to who manages changes in SAR coverage and ocean region satellites: the system software vs. the radio operator/officers

💭 Think About

• Think about whether an LES code is chosen mainly by ocean region satellite, by NAVAREA, or by which SAR/Coast Earth Station you want to reach • Consider whether standard ship Inmarsat terminals can fully auto-detect and switch SAR jurisdictions just from GPS position, or if a trained operator must confirm/update settings • Ask yourself: when you move between SAR regions or change the serving LES, who is expected—by GMDSS procedures—to make sure the distress hot-key calls go to the correct RCC/LES?

✅ Before You Answer

• Verify whether NAVAREAs (used for NAVTEX/SafetyNET) are the same thing as SAR regions or LES coverage areas • Check if GMDSS training materials say that Inmarsat terminals always auto-update hot-key menus solely based on position, or if operator actions are required • Confirm that a correct statement should reflect both SAR jurisdiction and the current ocean region/LES in use, not just one or the other

What statement is true regarding LES codes and Inmarsat “hot-key” alert default menus?

Automatic or manual updating of the LES code only needs to be done when switching to a different ocean region satellite.

The SAR jurisdiction software automatically updates the “hot-key” menu based on the vessel’s position.

The LES code is determined by the NAVAREA based on the vessel’s current position.

The LES code must be updated by the officers depending upon the SAR jurisdictions the vessel transits and current ocean region satellite in use.
