PLBs are received by the same Low Earth Orbit satellites that EPIRBS are picked up by, and they relay the signal to geostationary satellites, which relay to earth. The geostationary satellite does not directly receive signals from PLBs and EPIRBs. Coverage is pretty even worldwide between N70 and S70, and pretty spotty closer to the poles. BothPLBs and EPIRBS transmit on 121.5MHZ at 25 milliwatts for short range direction finding. The 121.5 transmission is no longer received by the LEO satellites, as of February, 2009.

Breathe in. Breathe out. Move on.
