🔍 Key Concepts

• Differences between satellite communications and terrestrial radio (VHF/MF/HF) • How frequency (VHF vs MF/HF) and line-of-sight affect range • What ARQ and SITOR are used for in marine digital communications

💭 Think About

• Ask yourself which of these systems depends on line-of-sight and which can work well beyond the radio horizon • Compare the typical coverage areas: coastal-only, regional/medium-range, ocean-wide, or near-global • Think about which system is specifically designed for long-distance ship–shore and ship–ship messaging regardless of distance

✅ Before You Answer

• Identify which option(s) are limited by the curvature of the Earth (line-of-sight) • Confirm which system(s) routinely provide ocean-wide or near-global coverage for ships at sea • Verify which of the MF/HF-based systems depend on propagation conditions and may have variable range, versus more consistent coverage
