L-3 Klein 5000 V2 Multi-Beam Side Scan Sonar

L-3 Communications Klein Associates have introduced their upgraded version of their System 5000. The L-3 Klein 5000 was the first commercial Side Scan Sonar system to employ cutting edge Multi-Beam technology. L-3 Klein has continually made incremental improvements to the System 5000 over the years. Now we have completed an upgrade and technology refresh to the 5000 and are proud to introduce the new L-3 Klein 5000 V-2. L-3 Klein has added a Reconnaissance Mode which extends long range coverage to 250 metres per side while maintaining along track resolution at 10cm to 38m, 20cm to 75m increasing to 36cm...

See It, Feel It

At Ocean Business, you not only have to listen to the sales pitch of the exhibiting companies or to look at the brochures. There are plenty of opportunities to see the equipment in action, to see what they do and to compare their work in reality. You can book for vessel demos or trials in a test tank.   Hydro International was invited to join Reson on Monday afternoon, before the opening of the show, to see the Reson sonars in action. Surveying the harbour of Southampton on board of Southampton's Port Management Protector, a few remarkable features were discovered... (read more)

Planet Ocean to Distribute Seastick

Planet Ocean has announced its partnership with Italian autonomous underwater vehicle manufacturer GABRI covering the UK and Ireland. The GABRI Seastick AUV incorporates several features that set it apart as an AUV and it can also be used with a tether turning it into a powerful remotely operated vehicle. The all-plastic construction gives it an extremely low magnetic signature. Together with the traditional forward dive controls and stern rudders the SEASTICK incorporates two, variable pitch thrusters using low power, silent, frictionless, magnetic induction motors which allow hovering and vertical movement in the water column. Fully customisable payload drawers and choice... (read more)

Underwater Inertial Navigation

Advanced Navigation has announced the release of its Sublocus underwater navigation system. This is an underwater inertial navigation system featuring north-seeking fibre-optic gyroscopes and accelerometers with a GPS receiver and pressure depth sensor. These are fused together in Advanced Navigation's fusion algorithm to deliver positional accuracy of 0.08% of distance travelled. The systems also provide highly accurate roll, pitch, heading, heave, depth and altitude. Sublocus is also available with an integrated RDI Workhorse Navigator DVL for combined acoustic and inertial navigation in the one product. Both models are supplied with a subsea GPS antenna and are rated to 3,000 metres... (read more)

Olex Integrates Spatial Inertial Navigation System into Marine Vessels

Nexans Olex has successfully integrated Spatial, an inertial navigation system, into its hydrographic vessel. Spatial is a ruggedised miniature GPS-aided inertial navigation system and AHRS that provides accurate position, velocity, acceleration and orientation. It combines temperature-calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor with an advanced GNSS receiver. Olex was seeking a new inertial navigation system in their multibeam sonar mapping systems for two key reasons. Firstly, they needed more accurate position and orientation data than their existing inertial navigation system could provide. Secondly, affordability was a central objective to help widen the market for inertial motion sensors and bring in... (read more)

Odom Multi-beam and e-Chart Software

Odom Hydrographic Systems has presented the ES3-M, a portable, beam-forming multi-beam that incorporates the best features of products from two industry leaders in one compact package.   The result of the combined efforts of Odom and Teledyne TSS is the uniting of Odom's ES3 multibeam with the survey proven DMS line of motion sensors. The technical cooperation of the two companies has resulted in a system with virtually zero fixed offsets (roll and pitch) between the two central components of the Hydrographic Multibeam System. Eliminating offsets means quicker installations, faster calibrations and reduced setup errors, helping to maximize productivity.  ... (read more)

Solid State Logging Compass

AOSI's EZ-COMPASS-3AL LOGGING Compass incorporates a three-axis Magnetometer with tilt and temperature compensation and a onboard rewritable memory that allows independent storage of up to 20,000 readings and transferable to any PC. The 1.5"x2.0"x0.5" module weights about 11° and generates heading, pitch, roll, magnetic field and temperature over RS232 or RS422 ports by using all solid state components. Compass measures tilt angles up to +/-90 arcdeg and includes tilt linearization, hard and soft iron calibrations and high rate of throughput without any moving parts. EZ-COMPASS-3AVL is a vertical version and EZ-COMPASS-3AHL is the horizontal version. Both versions fit 0.9" diameter... (read more)

Impact Subsea Launches ISM3D AHRS

Impact Subsea has announced the launch of a groundbreaking underwater Attitude & Heading Reference System - the ISM3D. It utilises high-grade MEMS-based accelerometers, angular rate gyroscopes and magnetometers that feed into a fusion engine driven by a dual-core micro-processor. The unit provides heading to ±0.5° of local magnetic north with pitch and roll to ±0.05° accuracy. For optimal performance, a hard and soft iron calibration can be performed on the unit once installed on the ROV, AUV or other underwater platform. This ensures that a consistently accurate heading is provided at all times. In areas where a large amount of steel... (read more)

Multibeam Echosounder for Medium to Deep Water

The RESON SeaBat 7160 multibeam echosounder has been developed for marine exploration, seafloor habitat mapping and hydrographic charting in medium to deep water (3 to 3,000m). Equipped with X-Range, it provides improved system immunity to external noise. The system can operate in water depths of between 3 to 3,000 metres, offering up to 512 high-density equidistant beams with a selection of coverage modes including features such as variable and steerable swath, together with real-time pitch and roll stabilisation maximising useable swath and performance. The SeaBat 7160 also provides the collection of high-density water-column data all wrapped up in a processing... (read more)

For nearly two years the sales team at VT TSS had been receiving orders for a combined installation of its Meridian gyro-compass and its Dynamic Motion Sensor (DMS). It was, therefore, suggested to VT TSS that it would be easier if the two units could be combined in one box. They would be easier to install and easier to use, and so the company developed the Meridian Heading and Attitude System (MAHRS). One notable new attribute is the deck plane correction, which was made possible by the use of an internal algorithm that can correct the gyroscope with highly accurate... (read more)
