NORBIT WBMS BASIC

A compact wideband bathymetric sonar with Ethernet integration and an integrated sound-speed probe. WBMS BASIC suits projects using a separately selected positioning and motion system. Pressure-rated versions support subsea installations as well as conventional pole or hull mounting.

Build a system around external navigation

WBMS BASIC is suited to installations where position and motion sensors are selected separately. Ethernet connectivity, an integrated sound-speed probe and broadband signal processing support vessel, USV and underwater-vehicle integration. Standard and narrow-beam configurations have different along-track beam widths. Housing pressure rating, vehicle connections and cable arrangements should be specified for the intended installation.

Applications and survey workflow

Bathymetric data supports harbour maintenance, dredging assessment, route surveys and the inspection of submerged infrastructure. Survey line spacing and frequency are selected to balance feature definition, coverage and the expected water depth.

Before mobilisation, the survey team defines the coordinate system, vertical reference and required deliverables. Mounting geometry, sensor offsets and time synchronisation are checked as one installation. Positioning quality, vessel motion and sound-speed conditions are reviewed during acquisition so that the final dataset can be assessed against the project specification.

Integration and deliverables

The selected hardware and software configuration determines the available outputs and interfaces. A practical workflow includes installation checks, a trial line, field quality control and documented processing. Depending on the sensor, deliverables may include a bathymetric surface, an inspection image, a point cloud or an interpreted sediment profile. Kordil can evaluate the platform, operating environment and intended use when defining the system configuration.
