Company RTSYS : underwater acoustics, underwater drones and sonar

RTsys is specialized in passive and active underwater acoustics and drones. We have more than 30 years of expertise and extensive business experience in the development of high-tech products. Our innovations are used not only in the civil sector, but also for defense, and are equipped with SDA (Synchronous Data Acquisition) technology, developed by our R&D team.
Within a context of increased monitoring of the marine environment, in connection with reducing noise pollution, we are the front-runners in acoustic monitoring, following huge investment in research and development, and in cooperation with the scientific community. Our recognized expertise in the defense sector and close collaboration with the French Navy enable us to develop innovative underwater detection tools and drones for use in anti-submarine warfare.

Core SDA technology
