Sensor Fusion Applications at EGU 2014

Optech, Canada, will be at the European Geosciences Union General Assembly 2014 from 27 April to 2 May in Vienna, Austria. Attendees with an interest in Lidar/sonar fusion or disaster response will enjoy Optech Worldwide Channel Partner manager Dario Conforti’s presentation explaining how Optech distributor Codevintec surveyed the wreck of the Costa Concordia. By combining a motion-compensated Optech ILRIS and a Teledyne RESON SeaBat multi-beam echo sounder on a research vessel, Codevintec mapped the wreck both above and below the surface of the water in a single pass, employing specialised software to merge and visualise their data in real time...

PAVS-150 Phased Array Velocity Sensor

Teledyne RD Instruments (RDI) has released the 150 kHz Phased Array Velocity Sensor (PAVS) for extended-range navigation applications. The PAVS150 is the industry's first 1,000-metre depth-rated compact Doppler Velocity Log (DVL) designed to provide precision velocity data at up to 500 metres of altitude above the seafloor. Driven by customer demand, this extended-range bottom-tracking capability makes the PAVS150 suited for aiding navigation systems on board any platform where the ability to transition from the deep waters of the open oceans to the shallow operating environments of the littoral zone is seen as a critical enabler.Designed with the Unmanned Underwater Vehicle...

UV Nitrate Sensor Added to Buoy System

The National Oceanic and Atmospheric Administration's (NOAA, USA) Chesapeake Bay Interpretive Buoy System (CBIBS) is a network of observing platforms that deliver meteorological, oceanographic and water-quality data live to the web at hourly intervals. The network has recently come under budgetary pressure and has been threatened with closure. In a cooperative effort to highlight the utility and value of the system, Satlantic (Canada) has recently partnered with CBIBS Project Manager Doug Wilson to provide a SUNA UV nitrate sensor for the Susquehanna site. It is hoped that the addition of the real-time continuous nutrient time series data will help promote the... (read more)

Canadian-UK Collaboration for Tidal Sensor Technologies

Canadian and British researchers will join forces to collaborate on two projects in developing new sensing technologies for tidal energy applications. The two project teams each feature industry and academic expertise from Canada and the UK and will introduce environmental monitoring and measurement sensor systems aiming to reduce risk and uncertainties associated with the deployment and operation of in-stream tidal devices. Sensor deployment and testing will be carried out in both Canadian and UK waters. Additional expected outcomes are to build Nova Scotia technical capacity in tidal energy and to contribute to the sector’s emerging global supply chain. The two... (read more)

Imagenex Adds Sonar and Sensor Interface Relay

Imagenex has released the Model 878 high-resolution sidescan sonar which runs two sonars simultaneously on each side at different sound wavelengths for enhanced image clarity. The new DT100 Sensor Interface Relay (SIR) provides a central connection point for bathymetric sensors including sonar (1 or 2 units), GPS, MRU, gyro/heading, and sound velocity. The DT100 multibeam echo sounder has been revised. The sidescan sonar Model 878 'RGB' (triple simultaneous frequencies) has undergone a facelift and become more affordable. Both models are equipped with an optional echo sounder and a built-in orientation module as well as depth and temperature sensors. Powered by... (read more)

Free TRIAXYS Next Wave Sensor Training

The TRIAXYS Wave sensor has proven itself capable in hundreds of deployments over the past 10 years. In 2010 it was upgraded to the TRIAXYS Next Wave sensor, with several new features added including continual wave sampling and expanded interface and memory capabilities. Reo Phillips is to give a free training session during Ocean Business 2011, Southampton, UK. Reservation is required.     Reo Phillips, AXYS Director of Operations and lead engineer in the development of TRIAXYS, will be on hand at the Ocean Business Conferenceto provide free training on how to use and get the most from this sensor....

CTD Sensor with Integrated UV Antifouling LED

A UV-LED (ultraviolet, 250-300nm @500µW, light-emitting diode) is integrated into the conductivity sensor quartz cell (patent pending) of Idronaut’s 305Plus CTD probe. The UV-LED sterilises the early growth of biofouling, thus eliminating environmental drift in a conductivity sensor. The Idronaut 305Plus CTD Probe complies with the European rules which do not permit the use of Tributyltin (TBT), a very toxic and poisoning (carcinogenic) substance which has been banned by the international government agencies. It is mandatory to protect any recessed conductivity cell, which presents a very small diameter and may get contaminated or even clogged. It also operates in polluted... (read more)

Longest Multi-Sensor AUV Pipeline Inspection

KONGSBERG has completed the world's longest multi-sensor AUV pipeline survey using one of its HUGIN 1000 Autonomous Underwater Vehicles (AUV). The pipeline inspection took place from 9th to 11th February 2011, in the Hjelte fjord near Bergen, Norway and the HUGIN 1000 was operated from the Royal Norwegian Navy vessel HNoMS Maloy. The subject of the inspection was two subsea pipelines going to the Mongstad oil refinery. The HUGIN 1000 AUV was equipped with a suite of KONGSBERG imaging equipment including the HISAS 1030 synthetic aperture sonar, EM3002 multi-beam echo sounder and an optical camera with LED lighting. The instruments... (read more)

XSENS Sensor Fusion DSP Module for Sagem

Sagem (Safran Group) is to integrate Xsens' sensor fusion signal processing modules in a new line of inertial navigation system products. As part of the supply agreement, Xsens has customised its 3D motion tracking sensor fusion algorithms to take full benefit of Sagem's Coriolis resonating gyros and silicon accelerometers.     Building on the XKF-3 sensor fusion algorithms for dynamic 3D orientation estimation, Xsens is delivering a custom DSP module which outputs very accurate vertical reference values, even in dynamic situations. Fabrice Delhaye, VP Sales of Sagem comments: "Xsens has a thorough understanding of our specification and application, which they... (read more)

First Seaglider with Rockland Scientific Turbulence Sensor

Kongsberg Underwater Technologies, USA, has delivered the first Seaglider vehicle equipped with a Rockland Scientific International (RSI) MicroPod turbulence sensor. The vehicle was commissioned by the UK's University of East Anglia (UEA). The MicroPod package is the result of extensive collaboration between KUTI and RSI in an effort to develop a sensor solution that is suitable for integration on Seaglider’s low-drag composite fairing. This sensor configuration minimises any potential impact on the high glide efficiency of the Seaglider. Ocean turbulence is being recognised as an increasingly important parameter for understanding and modelling climate change. It provides a measure of the... (read more)
