IMO New Rules regarding EPIRB 406MHZ

EPIRBs are important devices that, when a vessel is in distress, are carried from the vessel to a lifeboat or life raft, or when the vessel sinks, etc., the EPIRB’s water pressure sensor automatically detaches the main body and sends out a distress signal to communicate the emergency situation to a ground station. The distress signal can be transmitted manually or automatically, and is received by ground stations installed in each country via COSPAS/SARSAT satellites, which can decode and identify the name of the vessel and the location of the transmission. The 121.5 MHz distress signal can also be transmitted for homing by aircraft.

The new rules have been in effect since July 1, 2022!
