IXSEA, headquartered in Marlay le Roi,

France specializes in navigational, subsea positioning and imagery systems and solu- tions. This spring the company launched

SHADOWS, a new Synthetic Aperture

Sonar (SAS) device which is tethered to a ship and towed at specific depths and dis- tances from the ship. As a towed body, it is robust and rugged for rough sea conditions.

According to Anne Berg, of IXSEA,

SHADOWS is the first commercially avail- able off-the-shelf Synthetic Aperture Sonar (SAS) on the market. It is designed to be a quick and efficient high-performance sonar system with synthetic aperture processing, which offers unparalleled image quality in real-time. IXSEA's CEO Thierry Gaiffe hopes that SHADOWS will set a new industry standard for all sidescan sonar sur- veys. "This turnkey integrated survey solu- tion provides real-time, georeferenced mosaic output with 15 cm resolution over 600 m swath with full coverage directly beneath the transducer, therefore cutting survey time and costs."

SHADOWS side scan towed fish can be used for cable routing, offshore mining, pre-dredging surveys, small objects search on the seabed and shipwreck search and sal- vage. Not surprising is the fact that SHAD-

OWS is compatible with GAPS and POSI-

DONIA, IXSEA's Ulta Short Base Line (USBL) positioning systems.

SHADOWS includes SAS processing,

Gap filler frontal sonar module, GPS inter- face and gigabit data link. It is indeed the full package with fish towing system, work- station, software, raw data storage and backup solutions.

IXSEA, has a history of developing and providing innovative technology and expe- rience with for obtaining all sorts of images from the sea floor. It also integrates seismic, sonar and magnetometer imagery data in one spot for easy interpretation.
