Gyrocompass and Motion Sensor

The OceanFOG north-seeking gyrocompass is a compact survey-grade gyro offering extremely fast run-up times of less than three minutes and also features an integral motion sensor that calculates heave to a typical accuracy of 5cm or 5%. Unlikeolder and potentially unreliable ring-laser gyros with their inherent longrepair times, the OceanFOG uses state of the art fibre-optic gyros and MEMSaccelerometers. What setsthe OceanFOG has a standard list price at around two-thirds of the price of itsnearest competitor and that is comes with a conditional lifetime warranty.   (read more)

Sound Velocity Sensor

Valeport's miniSVS sound velocity sensor has been upgraded to offer higher specifications, with temperature or pressure measurement options. The miniSVS has been engineered to now include a high-accuracy PRT temperature sensor to increase versatility and compatibility with third-party systems. Together with standard titanium housing and a specially developed carbon composite sensor, the miniSVS offers durability and resistance to corrosion. The carbon composite sensor offers benefits in resisting deformity due to impact, thus not affecting calibration, and has virtually zero expansion with temperature, so that acoustic path length remains constant whatever the water temperature. Valeport's digital signal processing technique ensures that... (read more)

Sonardyne Motion Sensor Technology

Sonardyne International has launched a new marine Attitude Heading and Reference System (AHRS): Lodestar. Lodestar has been developed to overcome the problems associated with conventional sensor platforms. The Lodestar AHRS is a natural extension of the Sonardyne product range and has been developed for seamless integration with the company’s widely used LBL (Long BaseLine) and USBL (Ultra-Short BaseLine) acoustic positioning systems. It will also be welcomed by users with any requirement for motion compensation to support operations in any sea conditions. These are likely to include platform stabilisation, dynamic positioning, buoy monitoring, subsea construction and towfish and ROV/AUV operations. Available... (read more)

Multi-sensor Mapping

Integrating Data Streams for Coastal Science and Management
Among the most exciting advances in remote sensing are the innovations being made in multi-sensor data fusion. This can exponentially increase both the quality and quantity of information in the sensed environment. View Larger Map Scientists and practitioners in the National Oceanic and Atmospheric Administration (NOAA) and across the Federal government collect and use remotely sensed data for a wide range of activities including coastline mapping, military and disaster response personnel support, weather tracking, ecosystem monitoring and also to inform coastal planning officials and decision-makers on climate change adaptation strategies. Researchers continually strive to enhance the value, timeliness and efficient... (read more)

DP Reference Sensor Contract

Dynamic Positioning Services has been awarded a contract by Shell U.K. to supply and support a Guidance Navigation DP Reference sensor called RadaScan. The contract involves the installation of up to eleven RadaScan systems on board Shell’s contracted fleet of platform supply vessels, and the supply of ninety passive positioning transponders which will be installed on all Shell North Sea installations and mobile drilling unit supported from Aberdeen (UK). RadaScan is an advanced radar based positioning sensor for DP vessels, which was released to the market in 2006 following four years of development by Guidance Navigation, a Leicester-based company. The... (read more)

Field-swappable Sensor Heads

AML Oceanographiics in the final stages of field-testing the oceanographic industry's first field-swappable conductivity and temperature sensors. C-Xchange and T-Xchange are added to the devices for sound velocity and pressure, making all sensors of the company field-swappable.     Each Xchange sensor contains its own embedded calibration, meaning that individual sensor heads can be moved from instrument to instrument without recalibration. This flexibility promises to alter the way that users interact with their instruments.   With C-Xchange and T-Xchange sensor heads, CTDs  will no longer need to be returned to a service centre for recalibration. Similarly, individual instruments can be reconfigured on the... (read more)

Valeport Introduces Pressure Sensor

UK-based Valeport has added a pressure sensor to its range. The ultraP has been redesigned from the connector up. This has resulted in an exchangeable pressure sensor which is ultrafast, compact and dependable, providing levels of performance that are demonstrably ahead of competitive products. Suited to system integrators and OEM applications, the new ultraP has been designed to allow users to maintain the best possible accuracy with the facility to select the depth rating that best suits the user’s operational depth, with options from 10 through to 600bar. The pressure sensor, housed within the ultraP’s rugged titanium casing, is a... (read more)

Radar Level Sensor

The Valeport VRS20 Radar Level Sensor uses non-contact technology and can be installed easily. The device uses 25GHz pulsed k-band radar to measure water level to an accuracy of ±10mm. It has been designed to work with Valeport’s TideMaster tide logger or to operate as a stand-alone device with optional integrated GPRS telemetry. Alternatively it can interface with a third-party data logger. Non-contact radar technology avoids issues of traditional submerged devices, such as fouling and corrosion. Data collection is a simple process for the Valeport VRS20, with RS232, RS485 and SDI 12 communication as standard. With a wide range 9... (read more)
