Show Notes
How does a tiny device the size of a coffee mug connect you to a multi-billion dollar satellite network when disaster strikes? We explore the engineering behind EPIRBs, PLBs, and ELTs—from hydrostatic triggers to the global Cospas-Sarsat system. Discover why the switch to digital 406 MHz signals transformed search and rescue, and how GPS integration is cutting rescue times from hours to minutes.
