EpirbPlotter

EPIRBs (Emergency position-indicating rescue beacons) are small radio transmitters that SAR satellites and aircraft use to locate aircraft, vessels or individuals that need rescuing.

They are part of the Global Maritime Distress Safety System. EpirbPlotter allows you to use your PC and soundcard to decode the data messages from these beacons and, in the case of EPIRBs with GPS position reporting capabilities, to plot their positions on a suitable chart. Current generation digital EPIRBs transmit data on channels in the 406MHz band.
