🔍 Key Concepts

• GMDSS satellite EPIRB operating frequencies (what frequency is used to send the distress alert to the COSPAS-SARSAT satellite system?) • The difference between distress alert transmission vs homing signals and which equipment normally uses AIS for homing • Typical physical features of a float-free EPIRB installation (bracket, release method, lights)

💭 Think About

• Which answer choices correctly identify the standard distress alert frequency for GMDSS satellite EPIRBs? Eliminate any options that focus on older or non-satellite distress frequencies. • Which items listed are standard EPIRB features (like strobe light and float-free bracket), and which are more typical of other GMDSS equipment such as AIS-SARTs or radar SARTs? • Is a hydrostatic release a separate mounting component, or is it always built into the EPIRB itself? Think about what is actually attached to the vessel vs built into the beacon.

✅ Before You Answer

• Verify which frequency (in MHz) is used by COSPAS-SARSAT GMDSS satellite EPIRBs for the main distress alert. • Check whether AIS is a standard homing method for EPIRBs on your exam syllabus, or if homing is usually on another frequency. • Confirm that a float-free release bracket and strobe light are commonly associated with EPIRB installations designed for automatic activation when the vessel sinks.
