3DSS-iDX: Combined Side Scan and Multibeam System

Integrated INS Shallow Water Mapping/Imaging System

3DSS-iDX: Combined Side Scan and Multibeam System

3DSS-DX combines multibeam bathymetry and sidescan sonar data into a single, streamlined system. Utilizing a patented signal processing methodology, it extends the conventional extends the single angle-of-arrival principle used in interferometric systems to accommodate multiple simultaneous backscatter arrivals. When combined with the 3DSS-iDX Multibeam Echo-Sounder Signal Processing Engine, the result is unsurpassed resolution and bathymetric accuracy over swath widths that can exceed 14 times water depth. Accurate, high resolution, ultra-wide swath echo-sounding and 3D/2D imagery, with integrated real-time surface sound velocity, high accuracy INS position / attitude and optional RTK, PPK, PPP provide the best available hydrographic survey and imaging performance in shallow water. The real-time 3D software enables accurate measurement of complex seabed and water-column features like pipelines, wrecks, cables, subsea structures hazards and habitats.

At the heart of the 3DSS-iDX sonar is Ping DSP’s state-of-the-art SoftSonar™ electronics technology with ultra-low noise, wide dynamic range receivers, state-of-the-art acoustic transducer arrays, Gigabit Ethernet, easy-to-use software interface, and integrated support for a wide range of third party survey software and hardware.
