Compact and high-resolution curved array bathymetric mapping system by NORBIT. This all-in-one, tightly integrated broadband multibeam turnkey solution offers high-resolution bathymetry over a    wide swath.    The high-end sonar with   Applanix   WaveMaster   II   (globally leading   GNSS/INS   system)   embedded into the unit ensures fast and reliable mobilisation and the highest quality survey sounding in all conditions. The WBMS is based on a  flexible sonar platform that utilizes the latest analogue and digital signal processing.  With broad  R&D  expertise,  NORBIT  has developed,  from the ground-up,  exciting new technology that allows existing and new applications to benefit from the advantages offered by a compact wideband curved-array multibeam sonar and supported by DCT (Data collection Tool) for data acquisition.

The  NORBIT  WINGHEAD  i77h  is  a  compact  ultra-high  resolution  curved  array  broadband  multibeam  sonar  offering  tight integration with GNSS/INS (Applanix OceanMaster) that is designed for use in the most demanding operational environments  such  as  under  bridges  or  in  rough  sea  conditions.  Characterised  further  by  a  small  form  factor;  low  power  draw  and  tight  integration,  WINGHEAD  i77h  installation  can  occur  on  surface  survey  platforms  ranging  from  small USVs to large vessel permanent hull mounts. Supported by DCT (NORBIT Integrated Data Acquisition Software) for efficient survey data acquisition.

NORBIT’s bathymetry solution now includes data acquisition (DCT), this survey utility tool aims to simplify standard bathymetry survey operations. The bathymetry grid is displayed in a web browser allowing quick indication of the coverage and data quality in real-time while running the survey.

DCT is especially suitable for small boats and single-person operations as well as USV’s with low-bandwidth radio connectivity to the operator. DCT can be operated from a simple touch screen of a navigation plotter, tablet, smartphone, or PC and offers lean web browser accessible tools to efficiently plan the survey mission. With a tap of a finger or by a mouse click, users can draw lines, generate several wing lines with given spac-ing in just seconds. Each line can be adjusted, moved, rotated, resized, or deleted as needed. The available real-time displays in DCT are depth, sounding density, backscatter, and standard deviation. All four displays run concurrently on one, or several clients, e.g. skipper can view depth display and surveyor, or QA remote assistant can view standard deviation and sounding density display.
With the simple user interface DCT comes with a powerful data sharing capabilities based on PostGIS and GeoServer frameworks. DCT supports standard WMS and WFS protocols offering seamless integration with GIS software such as QGIS and other for immediate data access and further processing in any user workflow.

METRICA S.A. in collaboration with Norbit Subsea carried out a live demonstration for applications related to Berth Clearance and Pier Inspection using the Norbit iWBMSh compact multibeam system combined with Leica ScanStation P40.
The demo was held in Port of Patras.
