GeoSwath Plus

MBE GeoSwath Plus is an ultra high-resolution sonar system designed for multibeam bottom survey with accuracies according to the IHO SР-44 providing efficient simultaneous swath bathymetry and side scan seabed mapping. The system is a productive survey tool for the shallow water environment and inland waters achieving swath coverage of up to 12 times the water depth with up to 5000 soundings in one ping.

The system uses GeoSwath Plus software under Windows for real-time data acquisition, system calibration, post-processing including fair charts and 3D visualization. Data filtering and post-processing are possible with QINSy software as well. The typical set-up for over-the-side installation comprises a dual transducer head mounted onto a V-plate which can additionally hold a sound velocity sensor (MiniSVS), altimeter and a motion reference unit (MRU). Versions of GeoSwath Plus for AUV and ROV deployment are available.
