Defender Class boats are outfitted with a Category II, 406 MHz EPIRB
(Figure 3-99). These EPIRBs are manually deployable, self-buoyant units
equipped with a self-test feature that confirms operation as well as battery
condition and GPS position data. The EPIRBs use GEOSAR satellites that
are in geostationary high-earth orbit and can instantly relay emergency
transmissions. The EPIRB provides location accuracy to 0.05 NM and can
provide data to search and rescue (SAR) units within 5 minutes after
activation and signal detection.
