The company

RTsys is specialised 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 defence, 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 recognised expertise in the defence sector and close collaboration with the French Navy enable us to develop innovative underwater detection tools and drones for use in anti-submarine warfare.

Our Technology power-sda

Technology SDA14

The « Powered by SDA » core is used in all RTsys products. The SDA card is full of cutting edge reliable technology for active and passive acoutic applications. It offers substantial calculations capacity, in a compact and portable format whilst remaining highly energy efficient. Used in conjunction with a Linux operating system, it really is a unique product given its calculation capacity, its compact size and its low energy use.

  • Wide range operating power (500mW – 3W)
  • Raw power 7 GFlops / 266 GMACS
  • Linux operating system
  • Synchronous multichannel transceiver (16 RX / 4 TX)

Our core technology relies on the complete mastery :

Of signal processing :

  • Sonar signal
