Advanced Communications at Speed and Depth

General Magnetic Sciences (GMS) proposes to develop a system that uses magnetic waves for communications from shore, ship, aircraft, or space to a submarine, or other sub-sea platform, operating at any speed and at significant depth. No longer would it be necessary for a submarine break off its mission to communicate. The submarine could continue on station while receiving communications that use transmissions that would be directional and extremely low-probability-of-interception. Such a communications system, employing GMS''''s patented magnetic wavelength compression antennas, could transmit an extremely low frequency directional signal that could be received by an antenna on a submarine at significant depth many hundreds of kilometers away. GMS’s patented wavelength compression antennas are uniquely capable of efficient transmission of low-frequency signals by “compressing” long wavelengths to match a short conductor. These antennas could be broadband, also, allowing for use of higher frequencies at lesser depths, depending on the data transmission rate required. Likewise, a system using these same antennas could be used to provide communications from the submarine operating at significant depths and any speed to a unit above the surface many hundreds of kilometers away. Such a system has been proposed elsewhere as a separate effort.
