What is the primary function of the EPIRB?

The primary function of an EPIRB (Emergency Position Indicating Radio Beacon) is to send an emergency alert to search and rescue services. When activated, an EPIRB transmits a distress signal that includes a unique identification code linked to the registered owner's information and location. This signal is detected by satellites and relayed to ground stations that are responsible for coordinating search and rescue operations.

This capability is crucial for any maritime operation as it enables rescue teams to quickly locate individuals in distress, significantly improving the chances of survival. While communication with other vessels, navigation in poor weather, and recording messages may be important for maritime safety, these functions do not pertain to the specific role of an EPIRB. The device is specifically designed for distress situations, making its alert transmission to emergency services the articulation of its primary purpose.
