RTsys

Autonomous Underwater Vehicles, Underwater Acoustics and Systems Integration

RTsys specialises in the design and manufacture of innovative and reliable equipment and solutions in the fields of underwater drones or autonomous underwater vehicles (UAVs), underwater acoustics and systems integration.

RTsys has been developing state-of-the-art technologies for its clients on the global defence markets. Our high-performance systems provide clients with accurate information and the latest technologies in training and simulations.

Our strategy is to always satisfy our customers, and our work is based on ISO 9001 quality guidelines.

Ship sonar improvement

The OS3I solution improves current sonar performances and efficiency without having to replace the hull mounted and/or variable depth sonar by adapting itself to the existing hardware. The system is used for anti-submarine warfare, active and passive surveillance or acoustic simulation.

This fully-upgraded system provides high sonar performance at a lower cost. Sonar retrofit is therefore also quicker than the replacement of an entire sonar system.

Thanks to its numerical processing - beamforming up to 72 channels, 156kHz sampling, 24 bits - the user can choose between either standard signal processing such as beamforming as well as a new range of computer sonar processing like CW, combo and HFM, to name a few.

Furthermore, the modern man to machine interface of the OS3I, based on multiple HD-coloured monitors, simplifies the operation, provides accurate control of the reception panel and can be adapted to users' preferences.

Thanks to the mission simulator the OS3I can replay and generate a wide range of training missions like torpedoes or submarine approaches.

Underwater autonomous communication modules

RTsys manufactures autonomous modules that can send and receive voice and data across more than 2,000m in distance in noisy environments. These communication modules can additionally work as a digital player controlled by underwater acoustic communications. Our communication modules are well-equipped to combat shallow water and harbour environments, and are especially well-suited for harbour security, discrete underwater listening, underwater control and telemetry.

Passive acoustic systems

Thanks to its expertise in passive acoustics, RTsys can propose various configurations for underwater and surface zone surveillance.

Hydrophone network systems

Up to 72 hydrophones can be deployed on the seabed linked to the shore in real time through fibre-optic cables. From this onshore station, it can be possible to record, identify, localise and track different noise sources such as diverse submarines and surface ships.

Remote acoustic buoy

RTsys has designed the BA-SDA14, a small remote buoy equipped with a passive acoustic recorder. The recorder gives access to the acoustic data and the programming interface in real-time, at a maximum distance of 3,000m from a computer. The BA-SDA14 accepts up to four hydrophones, either passive or pre-amplified, depending on the type of noise to be recorded.

Furthermore, the BA-SDA14 can easily be programmed in autonomous mode, and can run for 12 days in continuous recording without having to recharge the battery. This system can be used for short-term passive acoustic surveillance and ship noise measurements.

Autonomous underwater vehicle: the COMET project

RTsys is working on a collaborative research project dedicated to developing a swarm of AUVs, or APV-Swarm.

The APV-Swarm is an autonomous and recoverable underwater vehicle dedicated to dedicated to various on-the-field applications.

Between three to ten collaborative AUV robots can be deployed simultaneously and with a distance of up to 1,500m between each AUV robot.

The COMET project will offer simplicity of implementation and reconfiguration, which will make cooperative underwater missions quicker and more effective.
