Hydroacoustic technologies including single and multibeam echosounders, and interferometric sonars are used by marine survey companies to produce bathymetric data that supports the sustainable use of marine sources.
The survey industry looks for technologies that can accommodate the strict requirements set by the International Hydrographic Society’s (IHO) S-44 standards, which have been set to ensure that the data provided is dependable and detailed enough for its intended application.
An echo sounder or sonar alone cannot be certified to IHO standards. Instead, the entire survey solution, including motion sensors and positioning system are rated as a single package able to meet one of five different levels with increasingly stringent demands.
GeoMB is a compact multibeam echosounder with integrated auxiliary sensors, delivering dependable, high-resolution bathymetric data. Operating at 400 kHz, it provides wide swath coverage and excellent vertical resolution, supporting surveys with demanding accuracy requirements.
GeoMB includes integrated Applanix navigation and an SVP, with serial support for third-party GNSS/MRU and SVP. Navigation data can also be output to external software.
