🔍 Key Concepts

• Marine Safety Information (MSI) and how it’s delivered globally • Difference between satellite-based systems and MF coastal radio systems like NAVTEX • Role of Inmarsat-based services in broadcasting safety information

💭 Think About

• Which option is specifically known as a broadcast service for MSI (navigational warnings, meteorological warnings, SAR information) via satellite, rather than a general communication or reporting system? • Which choice is associated with Enhanced Group Call (EGC) messages used for worldwide or ocean-area warnings? • Which option is not a satellite service but instead uses MF radio and is limited to coastal coverage, helping you eliminate it?

✅ Before You Answer

• Identify which system is explicitly designed for broadcasting Maritime Safety Information via satellite (not just any satellite communication). • Confirm which option is primarily a ship reporting program rather than an MSI broadcast system. • Verify which system is known for coastal, non-satellite MSI broadcast to rule that one out.
