Which of the following statements concerning the EPIRB system is true?
Official USCG Answer & Rule Citation
Correct Answer: Option C — The Inmarsat system will not provide alerts and position report for 406 Mhz EPIRBs equipped with GPS receivers.
Inmarsat satellites are designed for mobile communications and do not process 406 MHz EPIRB signals, which are exclusively handled by the COSPAS-SARSAT satellite constellation. While GPS-equipped EPIRBs provide precise location data, this information is relayed via the COSPAS-SARSAT system, not through the Inmarsat network infrastructure.
