🔍 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
