Which system monitors EPIRB, ELT, and PLB beacons?

• A. COSPAS-SARSAT
• B. NAVTEX
• C. INMARSAT B
• D. INMARSAT C

Answer: (A)

Distress beacon monitoring is handled by COSPAS-SARSAT, an international satellite-aided search-and-rescue system. It detects signals from EPIRBs, ELTs, and PLBs transmitted on 406 MHz (with older beacons also using 121.5 MHz for homing), locates the beacon, and passes the position to rescue authorities to initiate SAR operations. NAVTEX is a maritime safety information system that broadcasts weather and safety messages, not beacon monitoring. INMARSAT B and C are satellite communication networks for voice and data, not dedicated to monitoring distress beacons.
