The **NORBIT WINGHEAD i77h** is a compact, ultra-high-resolution multibeam sonar system designed for precise underwater mapping and inspection tasks. This curved array sonar excels in delivering detailed bathymetric data, making it essential for marine surveys in challenging environments.

Engineered by NORBIT Subsea, the WINGHEAD i77h features a 0.5 × 0.9-degree beam width, providing exceptional resolution for shallow water operations. Its true 1024-beam beamformer ensures precise results across various survey applications, supported by industry-leading acoustic robustness.

What is the NORBIT WINGHEAD i77h Multibeam Sonar?

The WINGHEAD i77h represents a breakthrough in sonar technology as the first cylindrical ultra-high-resolution curved array bathymetric system. Built on a modern analogue and digital platform, it incorporates advanced signal processing for rapid mobilization and high-performance surveys.

Key technical characteristics include integrated GNSS/INS for accurate positioning and real-time sound velocity measurement for reliable depth accuracy. The system's lightweight and compact design facilitates easy deployment, transport, and operation from small vessels or uncrewed surface vehicles (USVs).

This sonar outputs roll-stabilized bathymetry, high-quality imagery, and backscatter data, enabling comprehensive analysis of underwater terrains and structures. Its dedicated pipeline mode optimizes performance for inspecting pipelines and cables, a critical function in offshore infrastructure maintenance.

Core Functions and Technical Capabilities

At its core, the WINGHEAD i77h functions as a multibeam echo sounder, emitting acoustic pulses to map the seafloor and submerged objects with pinpoint accuracy. The curved array configuration allows for wide swath coverage while maintaining high resolution, outperforming traditional flat-array sonars in complex environments.

The system's 1024 beams provide dense data point clouds, essential for generating detailed 3D models. Acoustic robustness ensures consistent performance even in noisy or reverberant waters, such as harbors or estuaries. Real-time processing capabilities allow operators to review data on-site, reducing post-processing time.

Beamforming and Resolution Advantages

Unlike multi-sector sonars, the true beamformer in the i77h forms independent beams simultaneously, minimizing artifacts and maximizing data quality. This results in beam widths as fine as 0.5 degrees athwartship, capturing subtle seabed features like small rocks or erosion patterns.

Positioning and Environmental Integration

Integrated GNSS/INS compensates for vessel motion, delivering georeferenced data accurate to centimeters. Sound velocity profiling adjusts for water column variations, ensuring depth measurements remain dependable across salinity and temperature gradients.

Primary Use Cases for the WINGHEAD i77h

The NORBIT WINGHEAD i77h supports a broad spectrum of marine survey applications. In shallow water bathymetry, it maps coastal zones, rivers, ponds, and lakes with high fidelity, aiding in navigation charting and environmental monitoring.

For pipeline and cable route surveys, the dedicated mode enhances detection of crossings, free spans, and burial conditions. Structure inspections—such as quay walls, bridges, and offshore platforms—benefit from its imagery and backscatter outputs, revealing corrosion, debris, or structural integrity issues.

Harbor and estuary surveys leverage its compact form for confined spaces, while coastal operations provide data for erosion studies and beach nourishment projects. The system's compatibility with USVs and UUVs extends its reach to autonomous missions, reducing personnel risk in hazardous areas.

Why the WINGHEAD i77h Matters for Industry

In the global marine survey sector, the WINGHEAD i77h addresses key demands for efficiency and data quality. Offshore energy projects, including oil, gas, and renewables, rely on precise seabed mapping for site assessments, cable laying, and maintenance. Its high resolution minimizes survey revisits, cutting operational costs.

Hydrographic offices and port authorities use it for updating nautical charts and ensuring safe navigation. Environmental agencies benefit from its ability to detect habitat changes or pollution impacts with detailed backscatter analysis. The shift toward uncrewed operations amplifies its relevance, as USV integration supports scalable, cost-effective surveys.

Competitively, the i77h stands out for its balance of performance and portability. Compared to larger systems, it offers similar resolution in a deployable package, appealing to contractors serving diverse markets from Arctic coasts to tropical ports.

Consumer and Broader Market Relevance

While primarily an industrial tool, the WINGHEAD i77h indirectly benefits consumers through safer shipping routes, reliable energy supplies, and protected coastlines. Recreational boating and fishing communities gain from improved charts derived from its surveys. Research institutions use it for academic studies on marine ecosystems, contributing to global sustainability efforts.

In the commercial market, demand stems from expanding offshore wind farms, subsea cable networks for data centers, and port expansions worldwide. Regulations like those from the International Hydrographic Organization (IHO) mandate high-order surveys, which the i77h fulfills efficiently.

Deployment and Operational Advantages

The compact design—lightweight head and processing unit—enables quick setup on vessels as small as 5 meters or USVs. This portability suits remote or rapid-response surveys, such as post-storm assessments or emergency pipeline checks. Power efficiency supports extended operations without heavy generators.

USV and UUV Compatibility

Optimized for uncrewed vehicles, the i77h interfaces seamlessly with autopilot systems and remote control software. Low SWaP (Size, Weight, and Power) characteristics make it ideal for long-endurance missions, gathering data over large areas autonomously.

Technology and Innovation in Multibeam Sonar

NORBIT's WINGHEAD series pioneers cylindrical array technology, curving the transducers to match acoustic propagation patterns for uniform beam performance across the swath. Advanced signal processing filters noise, enhancing signal-to-noise ratios for clearer imagery.

Outputs include processed XYZ point clouds, water column data, and amplitude images, compatible with standard software like QINSy, Hypack, or NavLab. This interoperability streamlines workflows for surveyors worldwide.

Global Supply Chain and Availability

As a product of NORBIT Subsea, a Norwegian specialist in sonar systems, the WINGHEAD i77h is available through a network of marine technology distributors. Its modular design allows upgrades, extending lifecycle value. Manufacturing leverages precision engineering for reliability in harsh marine conditions.

Competition and Market Positioning

In the multibeam sonar market, the i77h competes with systems from Kongsberg, Teledyne RESON, and R2Sonic, distinguished by its ultra-compact form and pipeline-specific optimizations. Its price-to-performance ratio appeals to mid-tier survey firms entering high-resolution segments.

Regulatory and Adoption Trends

Adoption aligns with IHO standards for bathymetric surveys (S-44 edition), where order 1a/1b requirements demand sub-decimeter accuracy—the i77h delivers. Growth in autonomous maritime ops drives uptake, with USVs proliferating in Europe, Asia, and North America.

Case Studies in Real-World Applications

Surveyors have deployed the i77h for riverbed mapping in estuaries, revealing sediment dynamics critical for flood management.
