Side-Scan Sonar Deliveries

The MacArtney Group has during the winter and early spring delivered 6 EdgeTech 4200-FS side scan sonar systems in different countries. Three complete 300/600 kHz systems plus spares and one spare towfish has been delivered to The Royal Danish Administration of Navigation & Hydrography. This order also included 3 x 300 meter tow cable. One 4200 side scan system was sold to Geoconsult A/S in Norway for ROV installation and another AUV type 4200 system was delivered to Noordhoek, Holland, in connection with their purchase of 2 FOCUS-2 ROTV systems. The last system was delivered to GSI (Geological Survey of... (read more)

Forward-looking Sonar Upgrade

FarSounder will be launching a software upgrade for its FarSounder-500 and FarSounder-1000 forward-looking navigation sonars. The upgrade will increase the intuitive nature of the information and enhance users' understanding of the obstacles and sea bed ahead of their ship. The full release will be announced at SMM Hamburg and the Monaco Yacht Show later this year. At FarSounder’s recent customer demonstrations and technical training class, participants were introduced to a few of the upcoming new capabilities. A sampling of these features included Ping-to-Ping Sea Floor Stabilisation, Improved Sea Floor Imaging and Sea Floor Chart Overlay. FarSounder’s guests saw a demonstration... (read more)

Sentinel Sonar Order

The US Naval Underwater Warfare Center (NUWC) in Rhode Island (USA) has placed a contract with Sonardyne Inc., Houston (TX, USA) for the supply of an additional Sentinel Intruder Detection Sonar system.     The announcement follows the completion of rigorous acceptance and readiness trials by NUWC in 2008 when Sentinel was shown to meet the US Navy's performance requirements for diver detection. The latest contract adds an additional Sentinel to the new Integrated Swimmer Defence System. This is being led by the Program Executive Office, Littoral Mine Warfare (PEO-LMW - PMS480) and the first Sentinel was delivered to NUWC... (read more)

Acoustic Classification by Sonar

Disparate approach successful in cost-effective mapping
A breakthrough in signal conditioning has lead to significant improvements in single-beam and swath classification. With modern computers, this allows cost-effective bottom classification across multiple sonar platforms. The common dataset generated as a result of the highly successful shallow-survey conferences sponsored by the University of New Hampshire Ocean Mapping Group and the Defence Scientific and Technical Organisation of Australia is an ideal proving ground for classifying the same seabed using multiple platforms. The results of processing and classifying a common dataset are presented in this article. Acoustic seabed classification is in wide use for applications from habitat mapping to mine... (read more)

Sonar Uncertainty Instrument

L-3 Klein (USA) is to present the HydroChart 5000 (HC5000) Sonar Uncertainty Model at the upcoming Shallow Survey 2012 Conference to be held in Wellington, New Zealand, from 20th to 24th February 2012. The HC5000 is a portable, high-speed hydrographic survey system able to simultaneously collect IHO-quality bathymetry and co-registered, high-resolution, multi-beam side scan sonar data.   In order to qualify the system for use in hydrographic survey, L-3 Klein developed an uncertainty model which makes use of existing theoretical models of acoustic propagation, bottom and surface scattering, array processing, bathymetry signal processing, and statistical processing. This model was statistically... (read more)

Edgetech Sonar Demonstrated

EdgeTech is to demonstrate the latest technology in side-scan sonar and swath bathymetry at the upcoming US Hydro 2011 Conference in Tampa, Florida, from 25th to 28th April. EdgeTech's vessel, the Ocean Research II, will be outfitted with various equipment. EdgeTech's 4600 combines the high resolution 2D capabilities of a side-scan sonar with the 3D imagery of a multi-beam echo sounder. The result is a highly effective survey tool that produces real-time high resolution 3D maps of the seafloor and is simple to use and cost-effective. The 4200 is EdgeTech's most versatile side-scan sonar system and can be configured for... (read more)
