SBG Miniature Inertial Sensors SBG Systems released the Ellipse Se-ries, a new product range of miniature inertial systems replacing the IG-500 Series. For the same budget, custom- ers beneÞ t from higher accuracy, ad- vanced Þ ltering and features inspired from high end inertial navigation systems. This new series of miniature inertial systems beneÞ ts from a new design, new sensors, new capabilities and new algorithms. Weighting from 45 grams, Ellipse sensors are designed to be ß exible. The Ellipse-A model provides 3D orientation and heave. For navigation, users can connect their own GPS with the Ellipse-E, or use the internal one by choosing the Ellipse-N model. The amazing El- lipse-D completes this state-of-the-art miniature sensor family. This model is a little larger than the rest of the series because it integrates a Survey- grade L1/L2 GNSS receiver with two antennas for unmatched heading and position accuracy. ITAR Free Ellipse A, N, E models are available for order. The Ellipse-D model will be available on Q1 2015. www.sbg-systems.com Image: SBGBowtech Lamp Range ExtendedBowtech Products Ltd., a producer of subsea vision systems, announced the arrival of the LED-S-Series lamp, a smaller, 10,000 lumen version of its 20,000 lumen LED-V-Series underwater ß oodlight. The LED-S-Series lamp has been designed to offer a smaller, lighter and lower lumen output than its LED-V- Series using the same technology. Out- putting up to 10,000 lumens with a beam angle of 80 degrees in water (narrower angles are available) the lamp is suitable for illuminating large areas for HD view- ing tasks. Manufactured in corrosion re- sistant hard anodized aluminum with an acrylic window, the lamp is rated to op- erate at 6,000m ocean depth. The LED- S-Series lamp is available as either 100- 120Vac or 130-150Vdc, with a selection of connectors and connector positions available. www.bowtech.co.uk Hydro-Lek Manipulators on Italian Navy ROV Hydro-Lek delivered two Þ ve-function manipulators to Italian ROV manufac- turer, Ageotec, for the Italian Navy for submarine research and rescue. The ma- nipulators are Þ tted onto a Pegaso ROV system which also includes a motorized winch, silenced diesel power generator as well as a USBL and sonar system. Ageotec were selected by COMSUBIN (the Italian NavyÕs diver unit) to provide an open frame ROV system for visual and instrumentation research, objects recovery and underwater rescue. The system accomplished its Þ rst mission in April and is now fully operational. With a lift capacity of 40kg, the Hydro-Lek HLK-HD5 is a rugged work class Þ ve- function arm and incorporates a continu-ous jaw rotate assembly and three hy- draulic cylinders. Constructed from 316 stainless steel, HE30 aluminum and high density polyethylene, the HLK-HD5 is designed for the smaller ROV for heavy duty underwater tasks. www.hydro-lek.com Contact Rationalizing and Map Corrections Software Chesapeake Technology Inc. (CTI), a producer of real-time sonar acquisition and GIS based processing software for seaß oor mapping, announced two new capabilities that it claims will allow us- ers to better organize sonar contacts and improve sonar mosaic accuracy. New Contact Rationalizing, available on So- narWiz version 05.06.0052, is designed to allow a user to combine contacts into a single merged target with an average position. Also available with a software update is the Map Corrections feature. Similar to the Contact Rationalizing tool, it allows users to select a common target on separate sonar Þ les and calculate the offset between an average position. The Map Corrections tool goes an additional step by then applying the offsets to the sonar Þ lesÕ navigation thereby improv- ing the accuracy and image of the sonar mosaic.www.chesapeaketech.com Ellipse-N model with integrated GNSS receiver Image courtesy of Bowtech Photo courtesy of Hydro-Lek Image courtesy of CTI www.marinetechnologynews.com Marine Technology Reporter 59MTR #8 (50-64).indd 59MTR #8 (50-64).indd 5910/10/2014 12:22:45 PM10/10/2014 12:22:45 PM
