Modularity
Tethys One is a ready-to-use underwater drone, complete with a standard sensor package that guarantees advanced navigation and mapping capabilities.
Moreover, our underwater drone has the capability to bear diverse payloads and seamlessly integrates with environmental sensing, manipulation, or high-precision scanning functionalities. Enhance your 3D models by incorporating environmental data such as metal detection, current, pressure, temperature, oxygen levels, thickness, non-destructive testing (NDT), and beyond.
Click the payload tools
By emitting sound waves, sonar systems generate intricate images of underwater landscapes and objects, facilitating efficient seabed mapping and target detection.
Our piloting sonar, mounted on a tiltable head alongside the stereo cameras, allows the pilot to view both in front of and below the ROV, even in zero-visibility conditions.
In addition to a standard forward-looking multibeam imaging sonar, we also offer the option to install side-scan sonars.
