Norbit iWBMSh STX: Multibeam Sonar System


This most compact, highest resolution, tightly integrated, broadband multibeam sonar solution offering a curved array and GNSS/INS that is suited for the most demanding environments (Applanix OceanMaster). The iWBMSh STX is ready for rapid mobilisation and delivers highest XYZ performance for the price. The iWBMSh STX is fully integrated with the highest performing sensors to work in the most challenging environments (under bridges or in rough sea conditions). Small form factor, low power draw and tight integration allow 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 visualising the change in 3D bathymetry as a function of time. Hands-free system tuning ensures quality data on the first survey. Supported by DCT (Data collection Tool) for data acquisition.
