Hydro-Tech Marine is a leading developer of underwater and hydrographic survey equipment for USVs (uncrewed surface vessels) and unmanned underwater vehicles such as ROVs (remotely operated vehicles) and AUVs (autonomous underwater vehicles).
We are experts in acoustic and sonar technology and in addition to our off-the-shelf products, we can leverage our strong research and development capabilities to create bespoke underwater surveying solutions to meet unique and demanding requirements.
The MS400U is a compact, lightweight and low-power multi-beam echo sounder that has been specially designed for small unmanned platforms such as USVs. Featuring an integrated surface sound velocity profiler and AHRS (attitude & heading reference system), it is ideal for surveying 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.
