The MS400U is a low-SWaP (size, weight and power) multibeam echo sounder that has been specially designed for small USVs and surface platforms. Featuring an integrated surface sound velocity profiler as well as the Applanix POS MV SurfMaster marine inertial sensor, it is ideal for surveying underwater terrain and bodies of water such as lakes, reservoirs and rivers.
The system has been specifically optimized to deal with large changes in attitudes experienced by smaller unmanned vessels, utilizing 512 acoustic beams with sophisticated dynamically-focused beamforming technology. The MS400U meets the International Hydrographic Organization (IHO) accuracy standards for hydrographic surveys, as well as China's National Hydrographic Survey Code.
