ddu_1025_logo.jpgRTsys is a European company specialising in the development of underwater acoustic solutions for research, defence and offshore construction. RTsys develop all their hardware, electronics, and signal processing capabilities in-house, and regularly collaborate with major international research institutes on cutting-edge acoustic studies.

RTsys’ products include a range of highly configurable subsea acoustic noise recorders, with low power, multiple input and channel options, as well as moored or towed operating modes. These recorders are ideal for environmental monitoring, cetacean research, and noise impact studies for seismic, shipping, and subsea construction. RTsys also offer buoy-based recorders with real-time telemetry, for live monitoring of noise criteria exceedance.
