Q

What causes the SART to begin a transmission?

🔍 Key Concepts

• SART (Search and Rescue Transponder) basic function in the GMDSS system • Difference between continuous transmission vs replying to interrogation • Role of a shipborne X-band radar (9 GHz) in making a SART visible on the radar screen

💭 Think About

• Think about whether a SART is meant to transmit all the time, or only when another device "pings" it. • Consider how a SART helps rescuers locate you on their radar—what has to happen first for your signal to appear on their screen? • Ask yourself if the operator must keep keying the device, or if it works automatically once a certain external signal is received.

✅ Before You Answer

• Check whether the SART is designed to radiate continuously once switched on, or to reply to incoming radar pulses. • Verify the connection between X‑band search radar and the moment the SART starts to send out its distinctive signal pattern. • Confirm whether the human operator’s role is just to activate the SART, or to continuously key it for it to transmit.
