Norbit iWBMSh- High-End Turnkey Multibeam Sonar System for High-Resolution 3D Imagery and 4D Experience

Norbit iWBMSh STX is the first, ultra-high 3D resolution bathymetric surveying solution featuring Applanix High-End OceanMaster (globally leading GNSS/INS) system. The iWBMSh STX is fully integrated (IMU, Gyro, GNSS, multibeam, side scan, snippets, backscatter, water column) with highest performing sensors to work in the most challenging environments and sea conditions. Small and lightweight form, low power consumption and tight integration allows installation on any survey platform (permanent hull mount or pole mount). NORBIT STX uses rapid electronic transmit beam scanning to combine proven 2D bathymetry into 3D georeferenced bathymetry. For dredge application a 4D experience is achieved by visualizing the change in 3D bathymetry as a function of time.

Applanix High-End OceanMaster technology blends GNSS data and acceleration data from an IMU and heading from the GPS Azimuth Measurement System to produce a robust and accurate full position and orientation solution. The WBMS sonars are based on a state of the art analog and digital platform featuring powerful signal processing capabilities, offering roll stabilized bathymetry and several imagery and backscatter output

The compact and lightweight form enables for simpler, less robust mounting infrastructure than earlier generation multibeam sonar systems. Low power consumption allow flexibility for installing on very small survey vessels. All these features increase efficiency and for sure quality.
