Innomar SES-2000 AUV Sub-Bottom Profiler
The Innomar SES-2000 AUV model performs like a Innomar SES-2000 compact SBP and is intended to be used on AUVs working up to 2,000m below sea level.
The high ping rate, a small footprint and the possibility of transmitting sound pulses over a wide frequency range ensure echoprints 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 SES-2000 AUV 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 SES-2000 SBP data.
