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...

NexSon Bathmetrymetric and Oceanographic Sensor Packages

OceanTools Ltd announce the launch of their NexSon Bathymetric & Oceanographic Sensor packages. The NexSon Bathy/OSP contains high accuracy conductivity, temperature, pressure and altitude measurement probes for precision depth, altitude, conductivity, density and velocity of sound measurements. Systems are available in depth ranges of 700m, 1200m, 2000m and 4000m. Data from the subsea Bathy/OSP units is displayed on a stand-alone surface control unit, a NexSon sonar control unit, or on a PC running the Bathy/OSP software. The surface unit also contains an optional integral digital barometric pressure measurement. A range of output data strings are available to ensure compatibility with... (read more)

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...

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)

Xchange Sensor Heads Now Calibrated in Europe

AML Oceanographic (AML, Canada) has partnered with OSIL to offer Xchange sensor recalibration services at OSIL’s facilities in the UK. With a European recalibration centre, field-swappable sensor-heads become even more convenient for European users of oceanographic instrumentation. OSIL is expected to begin accepting Xchange sensor heads for recalibration by 1 March 2014. AML’s Xchange line is the industry’s only series of field-swappable sensor heads. Each sensor head contains its own embedded calibration, allowing the sensor to work with any AML instrument. Field-swappable sensors also streamline recalibration; instead of sending the entire instrument back to a calibration centre, a recalibrated sensor-head... (read more)

Tritech Sensor Selected for Student AUV

Tritech’s Micron sonar has been selected for the latest academic autonomous underwater vehicle (AUV). The acoustic design team at McGill Robotics, McGill University, Montreal, Canada, chose to incorporate a mechanical scanning sonar into their new-build AUV. The team now plan to integrate the Micron sonar into their software system in order to assist close-range positioning and detect objects in low-visibility environments. The team have also updated their AUV with new thrusters and are carrying out modifications to the frame and the pressure vessels. The Tritech Micron sonar is part of Tritech’s SeaKing range of mechanical imaging sonars. The Tritech Micron... (read more)

Ocean Observation Based on Networked Sensor Systems

The Ocean Observatories Initiative (OOI, USA) will construct a networked infrastructure of science-driven sensor systems to measure the physical, chemical, geological and biological variables in the ocean and seafloor. Greater knowledge of these variables is vital for improved detection and forecasting of environmental changes and their effects on biodiversity, coastal ecosystems and climate. Building on last century’s era of ship-based expeditions, recent technological leaps have brought a transformation in the approach to ocean research – the focus on expeditionary science is shifting to a permanent presence in the ocean. The ocean itself presents major obstacles to oceanographic exploration. We cannot... (read more)
