radio beacon

The Coast Guard recommends that mariners crossing the open ocean travel with multiple forms of communication, including radios and satellite and an electronic position radio beacon so authorities can find those needing rescue.

At about 12:48 p.m. the First Coast Guard District command center received an alert from an emergency radio beacon registered to the 55-foot commercial fishing vessel Miss Kara.

Another programme involving Dr Miller surgically inserts radio beacons into male pythons, turning them into "scouts" that travel around in search of a breeding female mate.

Another thing to consider: Mercogliano said the Titan lacked an emergency radio beacon that could have floated to the surface and started beeping if there was an emergency.

Fire department helicopters and ground crews searched for nearly an hour before a helicopter located a signal from an aircraft emergency position radio beacon near Beverly Glen Terrace and Beverly Glen Boulevard.
