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.
