Has GPS systems saved the lives of lost seamen in the past?

Question

In Mauritius,we just lost 17 men at sea,during cyclone:they probably had no electronic device to be spotted.Are these devices weatherproof?

Answer 1

GPS wouldn't be as helpful as a 406MHz EPIRB (Electronic Position Indicating Radio Beacon) or a DSC radio.

406MHz EPIRBs are devices that are normally mounted in locations that in the event of sinking or capsizing would float away from the stricken vessel. In addition they also have switches that will automatically activate the EPIRB when it floats off of it's bracket. When activated SARSAT satellites pickup the signal and within a short time are able to triangulate the position of the EPIRB and pass that position on to Search and Rescue Crews.

DSC radios, in particular ones that are designed for larger ocean going vessels and are compliant with the latest SOLAS (Safety of Life at Sea) regulations are connected to GPS receivers. In the event of an emergency the radio operator merely presses a button or two and a signal is automagically transmitted that includes the vessels location (from the GPS) the name of the ship, and nature of distress. This signal is transmitted on frequencies that are monitored by all ocean going vessels.
