🔍 Key Concepts

• INMARSAT SafetyNET™ is used for Maritime Safety Information (MSI) broadcasts • Understand what types of messages are considered MSI: navigational warnings, meteorological warnings/forecasts, SAR (search and rescue) information, and piracy/security-related warnings • Know the difference between safety broadcasts and commercial / routine traffic lists

💭 Think About

• Which of these options clearly looks like routine or commercial communication rather than a safety-related broadcast? • Think about what SafetyNET™ is designed to do globally: which types of information must reach all ships in an area automatically for safety of navigation? • Ask yourself: does SafetyNET™ normally carry messages between individual ships and coast stations, or primarily one‑to‑many broadcasts for safety?

✅ Before You Answer

• Verify which types of information are officially defined as Maritime Safety Information (MSI) under GMDSS • Identify which choice refers to non‑safety / commercial traffic rather than safety information • Confirm that SafetyNET™ is a broadcast system (one‑to‑many), not a routine traffic exchange or calling system
