McMurdo launches emergency beacons with GPS, GLONASS, Galileo

September 7, 2016By
The McMurdo SmartFind and Kannad SafePro distress beacons support beacon transmission, GNSS for location positioning, and AIS for localized connectivity.

Emergency preparedness company McMurdo has launched a new family of Emergency Position Indicating Radio Beacons (EPIRBs) that will accelerate the search-and-rescue process by combining multiple frequencies — including GNSS — into a single EPIRB product. The McMurdo SmartFind and Kannad SafePro EPIRBs are distress beacons that can support each of the four frequencies used in the search-and-rescue process: GNSS for location positioning, 406 MHz and... read more
