Introduction
ORCA®dsc (Overboard Recovery Communications
Apparatus – digital selective calling) is a personal water
activated man overboard (MOB) alarm beacon developed
by BriarTek, Inc. The beacon is utilized by mariners to aid
in the rescue of an MOB victim. ORCA®dsc communicates
with existing marine radio communications infrastructure to
alert vessels of an MOB event on a DSC-equipped marine
VHF radio (VHF radio). ORCA®dsc also includes a 121.5
MHz transmitter module which enables users equipped
with a radio direction finder (DF) to locate the MOB.
