Abstract
A survival radio of the type useable in search and rescue operations and carried by the party to be rescued is described. The survival radio includes a GPS receiver, a transceiver and a microcontroller. The microcontroller responds to interrogation messages containing a predetermined identification code for the survival radio to cause a transceiver to transmit a geographic location of the survival radio as derived from GPS signals.
