"Innomar compact-usv" Sub-Bottom Profiler

Picture compact-usv SBP

The "Innomar compact-usv" model is intended to be used on uncrewed surface vehicles (USV / ASV). The high ping rate, a small footprint and the possibility of transmitting sound pulses over a wide frequency range ensure sub-bottom data with excellent resolution and very good sediment penetration. A user-friendly Windows data acquisition and system control software (SESWIN) is used for remote (Ethernet) operation. The "Innomar compact-usv" model acquires full-waveform data that can be processed with any seismic software (SEG-Y format). Innomar also provides the ISE post-processing software specialized on the Innomar SBP data.
