🔍 Key Concepts

• Iridium satellite terminals capabilities for emergency use • Role of a Rescue Coordination Center (RCC) and how it receives alerts • Difference between an automatic distress function and a normal text/voice message

💭 Think About

• Ask yourself whether Iridium normally has a special Coast Guard "monitoring channel," or if it works more like a phone/text system. • Consider how a shipboard terminal could quickly alert a specific RCC when time is critical—would it rely on the network to choose, or on something pre-set by the user? • Think about how GMDSS-style equipment usually sends distress alerts: do you just write the word "Distress" in a message, or is there a dedicated emergency function?

✅ Before You Answer

• Verify whether Iridium uses channels like VHF, or numbers/programmed contacts like a phone. • Check which option describes a preconfigured emergency procedure rather than an ordinary message. • Confirm that the correct choice allows you to select a specific RCC, not just send a general message into the system.
