Canada-based GeoSpectrum Technologies, a subsidiary of Elbit Systems, on 10 August launched its C-Bass family of compact Very Low Frequency (VLF) long-range acoustic underwater transducers.
Traditional high-power underwater VLF sources are extremely large, costly and manpower-intensive to run, according to GeoSpectrum, so there is a clear market appetite for smaller, lightweight and more deployable solutions.
With a range of more than 2,500km, C-BASS is suitable for a subsea applications such as: communication/transmission from shore or surface units to submarines; diver alert and communications; communication with UUVs for control/positioning; minesweeping; and 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 20cm-diameter configuration that can fit in a medium-sized UUV up to the 1.1m-diameter unit used in a multisource high-power configuration for seismic exploration.
