GeoSpectrum Technologies, an Elbit subsidiary, has unveiled the C-BASS family of compact Very Low Frequency (VLF) long-range acoustic underwater transducers. According to the company, the system generates high power at very low frequencies from a small source which the firm claims is a technological challenge, with current high power underwater VLF sources available on the market being extremely large, costly and requiring a crew of at least a dozen people to operate.

Addressing these deficiencies, GeoSpectrum introduces the patented, C-BASS family of underwater transducers, offering the market a deployable system that is small in size and weight but still maintains the high-power and frequency range (bandwidth) of legacy systems. The company says it is robust, affordable, easy to operate and has ranges exceeding 2500 km with the ability to effectively operate under ice. Applications include communication/transmission from shore or surface units to submarines, divers’ alert and communications and communication with Unmanned Underwater Vehicles (UUV) for control/positioning or mine sweeping, as well as augmentation of submarine signatures when transiting in or out of ports or narrow passages.

C-BASS transducers are available in a variety of sizes and configurations from the 20 cm diameter configuration that can even fit in a medium UUV up to the 1.1 m diameter unit used in a multi-source high-power configuration for seismic exploration.
