Question 32E5
Element 7R (GMDSS-RO)What is an example of a locating signal?
Explanation
An EPIRB (Emergency Position-Indicating Radio Beacon) is explicitly designed to transmit a distress signal containing position information, allowing search and rescue services to precisely locate the beacon and the vessel or person in distress. A float-free EPIRB automatically activates when submerged, sending signals via satellite and a homing frequency to aid in quick localization.
SSB phone traffic and ship-to-shore transmissions are forms of general radio communication; their primary purpose is not to act as a dedicated locating signal in an emergency. Loran C was a terrestrial radio navigation system that allowed a receiver to determine its *own* position from ground-based transmissions, not for a beacon to transmit a signal to be located by others.
