🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) equipment capabilities and typical ranges (VHF vs MF/HF vs Inmarsat) • Difference between line-of-sight comms (VHF) and long-range comms (MF/HF and satellite) • How simultaneous communication with both an RCC (Rescue Coordination Center) and SAR units (OSC vessel, aircraft) is normally organized in a real SAR case

💭 Think About

• First, decide which systems are truly suitable for long-range communications beyond line of sight, especially with shore-based RCCs. • Then, think about which systems are practical for direct communication with SAR aircraft and OSC vessels at the same time, not just shore-based RCCs. • Consider how, in real SAR operations, the RCC typically coordinates with multiple units: does it require all units to have the same type of equipment, or can it relay via shore-based systems?

✅ Before You Answer

• Verify which options are line-of-sight only and which provide global/long-range coverage. • Check which equipment types are commonly fitted on SAR aircraft and surface SAR units for direct ship–unit voice communications. • Confirm whether any option depends on the RCC relaying messages, versus allowing you to talk directly to both RCC and SAR units on appropriate follow-on frequencies.
