EPIRB = Emergency Position Indication Radio Beacon
It's a device that is activated when immersed in water and emits a continuous signal alerting authorities to the existence of a distress situation. They work on two frequencies, 121.5 and 406.025. The 406 signal can be received worldwide by satellites and continuously update the Coast Guard with your GPS coordinates.

( I did not go on that site)
No, you can't get this option on your standard GPS. This system is used when your boat sinks and you are floating around at sea. You keep it attached to your life vest, or something along that line.
