What is the primary purpose of an EPIRB in GMDSS?
Answer: To transmit a distress alert via satellite when a vessel is in peril
An EPIRB (Emergency Position-Indicating Radio Beacon) transmits a distress signal via the Cospas-Sarsat satellite system to alert rescue authorities when a vessel is in danger.
What does a Category I EPIRB do that a Category II EPIRB does not?
Answer: Automatically activates and floats free when submerged to 1-4 meters
A Category I EPIRB is mounted in a float-free bracket and automatically activates and floats free when the vessel sinks to 1-4 meters depth.
How long must a GMDSS EPIRB be capable of operating after activation?
Answer: 48 hours
A GMDSS EPIRB must be capable of continuous operation for at least 48 hours after activation to allow time for SAR response.
