When you activate a plb it sends out two signals a powerful digital signal at 406 mhz that is received by the cospas sarsat international search and rescue satellite system and a low power analog honing signal at 121 5mhz.
Satellite distress beacons.
Plbs must be registered.
An emergency locator beacon is a radio beacon a portable battery powered radio transmitter used to locate airplanes vessels and persons in distress and in need of immediate rescue.
A recognized beacon can operate on one of the three currently cospas sarsat satellite compatible frequencies.
121 5 mhz distress beacons are no longer detected by satellite and are no longer licensed for use.

Distress signal is sent to a satellite.
In october 2000 the international cospas sarsat program announced at its 25th council session held in london uk that it plans to terminate satellite processing of distress signals from 121 5 and 243 mhz emergency beacons on february 1 2009.
Some plbs also allow gps units to be integrated into the distress signal.
Like epirbs and elts all plbs also have a built in low power homing beacon that transmits on 121 5 mhz.
