Innomar Essential Parametric Sub-Bottom Profiler
Innomar Essential Parametric Sub-Bottom Profiler
Innomar Essential SBP model is intended to be used on small boats and uncrewed surface vehicles (USV / ASV) in inshore and nearshore environments. 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.
Electronic beam stabilization across (roll) or along track (pitch) is used to compensate for wave-induced vehicle movements.
A user-friendly Windows data acquisition and system control software (SESWIN) is used for remote (Ethernet) operation. Innomar essential 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.
