Cetus VLF Sonar

Very Low Frequency for Very Long Ranges

VLF Sonar Being RecoveredThe Cetus Very Low Frequency (VLF) Sonar System from GeoSpectrum leverages the ability of low frequency underwater sound to travel very long distances, thereby enabling long distance detection of submarines. This provides the ability to apply active sonar to detect even the quietest submarines at extended ranges. VLF active sonar has the potential to allow detection from both reflection and resonance, effectively undermining submarine concealment measures. Cetus can also be used for long range communications with submarines, UUVs and other underwater assets.

Contact GeoSpectrum Technologies for more information.

WaveAway – Diver Deterrent System

Continuously Available Anti-diver Defense

Family of Projectors Used in Diver Deterrent SystemThe WaveAway diver deterrent system from GeoSpectrum provides a less-than-lethal means against hostile divers and swimmers. It is based on a customized low frequency sonar system source that can operate continuously. WaveAway transmits acoustic noise that deters and neutralizes incoming divers and swimmers with escalating effects. WaveAway will dismantle the intruder’s motivation and capability to approach the protected site and cause them mission abort or failure to execute. System operation is not dependent on detection of the intruders and does not involve firing weapons of any kind.

Diver Deterrent System ProjectorWaveAway can be installed statically in strategic locations or operated from a patrol boat or unmanned surface vehicle (USV). WaveAway can be part of an integrated maritime security suite to include active and passive diver detection systems, radar, Electro-Optics, video surveillance, physical barriers, command & control, and more.

LRAM – Long-Range Acoustic Messaging System

Long Range Covert Communication with Submarines

LRAM System Components

LRAM System Concept Illustration

LRAM System Concept with Expendable Buoy and Persistent USV Options

LRAM provides integrated under water (UW) communications covering both broad ocean areas and the shallows up to the shore line.

The common LRAM modem architecture can be applied to submarine, UUV, and diver communication as well as remote activation of underwater devices. LRAM also enables the production of a multimode receiver capable of receiving all modes, and will allow 2-way communications with a distressed submarine.

LRAM utilises a proven scalable modem software architecture designed to provide robust, reliable, and power-efficient through-water communications to extended ranges.

The system enables co-operative Anti-Submarine Warfare (ASW) between submerged submarines and UUVs and air and surface assets. LRAM provides on-demand connectivity to submarines and UUVs operating in direct and associated support, increasing the value of UW platforms as fleet assets.
