406 MHz EPIRB
The Emergency Position Indicating Radio Beacon (EPIRB) is a small battery-powered device that is carried onboard boats. Vessels operating on the high seas (beyond the 3 mile territorial line) are required to carry a 406 MHz EPIRB. Although there are different types of EPIRBs, all will float and continue to send a signal for 48 hours. The EPIRB must be tested when it is installed and at least once every month. For more detailed information regarding EPIRBs and registration with NOAA, please see the U.S. Coast Guard web site.

When activated, the EPIRB sends a signal to satellites orbiting the earth. The satellite then transmits the signal from the emergency beacon to a land-based station. Personnel at the station determine the EPIRB's position based upon the signal and deploy emergency response team.
