GeoSpectrum Technologies Selected to Supply Long-Range Acoustic Messaging (LRAM) System to Undisclosed Customer

GeoSpectrum Technologies, a Canada-based wholly-owned subsidiary of Israel’s Elbit Systems, announced that it was selected to deliver its Long-Range Acoustic Messaging (LRAM) system to another Western customer.

The LRAM system is a through-water acoustic communications system optimized for robust operation over a long range. It is designed to send acoustically encoded tactical messages from a user-controlled station to a submerged submarine or other underwater assets. Two-way communication can also be provided.

This new contract follows a recent successful delivery of LRAM equipment to the Canadian Government.

“The LRAM system has demonstrated its capacity to provide long-range, reliable LF acoustic communication in a range of NATO exercises in diverse global arenas. The integration of cutting-edge acoustic transducers yields outstanding sub-sea communication performance and we are excited about the growing interest in our systems,” said Paul Yeatman, President of GeoSpectrum.

The LRAM system provides the capability to covertly communicate with a submarine on an as-needed basis without requiring the submarine to be at periscopic depth. Such communication can be vital for tactical comms with the submarine (mission re-tasking, target cuing, Blue-on-Blue prevention, etc.) or enhancing submarine safety by routine monitoring and handling of distress situations. Communication can be in diverse topologies from a ship or off-shore site directly to the submarine direct water-to-water or from a command station using an acoustic link on an expendable buoy, Unmanned Surface Vessel (USV) or manned vessel.

The system configurations support strategic communication for ranges up to thousands of kilometers applying GeoSpectrum’s unique Very Low Frequency (VLF) source as well as tactical communication for up to hundreds of kilometers using Low Frequency (LF) sources. Also, it can provide a means for reliable and secure remote acoustic activation or communications with Unmanned Underwater Vehicles (UUVs) and divers.
