Aquapix - Model INSAS -High-Resolution Interferometric Synthetic Aperture Sonar (InSAS)
Kraken has successfully developed and deployed a high-resolution Interferometric Synthetic Aperture Sonar (InSAS) called AquaPix®. AquaPix® is capable of providing detailed seabed images with a constant resolution better than 3cm x 3cm out to a range of 300m from each side of an underwater vehicle (600m swath). It can also produce 3D bathymetric data with a resolution better than 25cm x 25cm out to full range while delivering very high depth accuracy, in compliance with IHO S44 special order requirements.
AquaPix® is designed for use onboard Autonomous Underwater Vehicles (AUVs), Remotely Operated Tow Vehicles (ROTVs), Remotely Operated Vehicles (ROVs) and Tow Bodies. Its modular and scalable design supports variable length arrays, variable platform speeds, variable swath widths and interferometric bathymetric capabilities.
