Volumetric 3D acoustic beamforming and PIPE parallel processing

Coda Octopus Echoscope real-time 3D sonars utilize proprietary volumetric phased array technology.

Unlike conventional multibeam echosounders that sweep narrow swaths along the vessel track, Echoscope generates an expansive 3D acoustic pyramid up to 50° × 50°, computing over 16,000 to 20,000 spatial coordinate points per ping.

This capability enables continuous real-time 3D monitoring of dynamic subsea operations regardless of water turbidity or current speed. The 375 kHz mode provides survey ranges up to 150+ meters for search and navigation, while the 610 kHz mode offers millimeter-level target inspection.

The Parallel Intelligent Processing Engine (PIPE) processes multiple independent 3D acoustic datasets simultaneously without reducing ping rates, enabling concurrent seabed mapping and automated tracking of moving subsea targets.

Precision inertial navigation and dynamic heave compensation

Accurate subsea point cloud georeferencing relies on high-grade motion compensation. The Coda Octopus F180 Series combines tactical-grade inertial sensors (IMU) with multi-frequency GNSS receivers in a rugged subsea-rated enclosure.

Advanced Kalman filtering continuously fuses GNSS carrier phase measurements from twin antennas with inertial data, providing True Heading accuracy of 0.05° at 2 m baseline and dynamic roll and pitch precision of 0.025° even in heavy sea states.

Real-time heave calculations achieve 5 cm or 5% accuracy, delivering low-latency motion corrections to Echoscope 3D sonars and multibeam sonars via Ethernet and serial interfaces.

Digital geophysical data logging and processing in DA4G

Coda Octopus DA4G series geophysical workstations provide high-performance digital acquisition for marine site surveys, supporting simultaneous inputs from side-scan sonars and sub-bottom profilers.

Input channels feature 24-bit ADCs with dynamic range exceeding 90 dB and analog bandwidth up to 100 kHz. Optical and galvanic isolation protects measurement circuits from vessel electrical noise.

Surveys are recorded in native Coda (.cod) format with export to XTF and SEG-Y standards. Integrated GeoSurvey and Survey Engine tools automate slant-range correction, TVG gain compensation, and seabed mosaicing.

Diver Augmented Vision Display (DAVD) in zero-visibility diving

Subsea construction and rescue operations in zero optical visibility carry high operational risks. The Coda Octopus DAVD system projects real-time 3D sonar imagery from Echoscope directly onto a transparent HUD in the diver helmet.

Divers perceive underwater structures, valves, pipelines, and seabed obstructions with complete clarity, receiving real-time navigation waypoints and instructions from the dive supervisor.

Surface supervisors monitor the exact 3D spatial position of divers relative to subsea assets, cutting dive operation durations by 50 to 70 percent while enhancing mission safety.

Subsea wet-mateable interconnects and ruggedized cabling

Hydroacoustic survey reliability depends on marine cable integrity. Coda Octopus equipment utilizes industry-standard SubConn and Impulse subsea wet-mateable and dry-mateable connectors.

Interconnect cables feature heavy-duty polyurethane (PUR) outer jackets resistant to abrasion, UV radiation, hydrocarbon oils, and hydrostatic pressure up to 3000 meters depth.

Internal conductors isolate power lines from high-speed Ethernet data pairs, with optional integrated Kevlar strength members designed to withstand multi-ton dynamic towing loads.
