“Lockheed Martin’s technology, paired with Carroll Technologies Group’s presence and experience in the mining industry, provides trapped miners the means to communicate with rescuers when no other form of contact is possible,” said Richard Holmberg, Lockheed Martin’s vice president who oversees the program. “It’s gratifying to apply our advanced communications and signal processing expertise in a new way to save lives.”  

TTE technology eliminates the need for transmission wires and in-ground infrastructure required for standard radio communications. MagneLink also is capable of interfacing with miners’ hand-held emergency radios.

Lockheed Martin has conducted several successful in-mine demonstrations of the system and is working with the Mine Safety and Health Administration to approve the equipment for use in mines.
