NORBIT iWBMSe
NORBIT iWBMSe
An integrated multibeam survey package with Applanix SurfMaster GNSS/INS, intended particularly for sheltered waterways. Its compact installation supports harbour, lake and river work where an economical integrated system is preferred and vessel motion can be managed within the survey requirements.
Integrated surveys in sheltered waters
iWBMSe combines broadband sonar with SurfMaster navigation for harbour, lake, river and nearshore surveys. Expected vessel motion, heading performance and attitude accuracy should be assessed together. NORBIT currently lists this platform as a Legacy product. The technical table follows brochure PS-150006-16; navigation specifications from higher-performance iWBMS variants have not been transferred to this model.
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.
