The ‘ahoi -underwater modem’ is a wireless networked sensing device that is integrated into micro autonomous underwater vehicles (µAUV). Underwater communication is a mandatory requirement as enabling technology. For this, only acoustic communication is suitable since radio waves suffer from heavy absorption in water, and poor visibility exclude optical approaches. The 'ahoi -underwater modem' is the only acoustic modems that can easily be integrated into the µAUVs.
μAUVs enable automated, unsupervised environmental underwater monitoring, inspections, and interactions with the environment. Applications range from automated water-quality monitoring over inspections of bridges and wind parks, to supporting divers in dangerous missions.
