🔍 Key Concepts

• EPIRB (Emergency Position-Indicating Radio Beacon) primary purpose and who conducts global distress monitoring • The COSPAS-SARSAT system and what it uses to detect 406 MHz distress signals • Difference between shipboard radio listeners versus an automated international satellite system

💭 Think About

• Which of these choices could realistically provide continuous worldwide coverage for distress signals from small vessels? • Which organizations or systems are specifically designed to receive 406 MHz EPIRB signals as part of an organized search and rescue system? • Ask yourself: would individual ships normally be tasked to monitor EPIRB frequencies, or is there a dedicated global system for that?

✅ Before You Answer

• Confirm that Category 1 EPIRBs are 406 MHz beacons intended for automatic alerting of rescue authorities, not just nearby ships • Check which option is capable of global, automatic, round‑the‑clock monitoring of distress beacons • Eliminate any answer that represents a type of vessel rather than a dedicated, worldwide distress monitoring system
