🔍 Key Concepts

• Search and Rescue Transponder (SART) as part of GMDSS equipment • Difference between radar transponders and satellite beacons (EPIRBs at 406 MHz) • Which radar band (X-band vs. others) is normally used for small-craft and rescue target detection

💭 Think About

• First, decide: does a SART work with ships’ radar or with satellites? Match that to the options. • Think about which GMDSS device sends a 406 MHz distress alert to a satellite and what its proper name is. • Recall which radar band (X-band or Y-band) is actually used in standard marine navigation radars for target detection and plotting.

✅ Before You Answer

• Be clear whether a SART is triggered and seen on nearby ships’ radar screens or in a satellite control center. • Verify which equipment is specified in GMDSS to transmit at 406 MHz (hint: not a radar transponder). • Confirm which band is the standard marine radar band used to display the characteristic SART response pattern.
