VT TSS Launches MAHRS

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)

LinkQuest Data Fusion Functions

LinkQuest high-speed underwater acoustic modems have recently incorporated data fusion functions. All LinkQuest modems can now interface to up to eight underwater sensors or devices using the RS232 interface. These systems can also sample up to sixteen analogue inputs simultaneously and provide up to 1Gbytes of permanent storage on a compact flash disk. Using this platform, LinkQuest Inc. delivered two sets of UWM2000 modem systems to Fugro Change Inc. Early 2003. These systems interface to a DigiQuartz depth sensor, a load cell and a compass and pitch/roll sensor. The sensor data is stored on a compact flash data logger at... (read more)

CodaOctopus F180s for Fugro

CodaOctopus has recently delivered two new F180 position and attitude systems to Fugro Survey Pty in Perth, Australia and conducted on-site operator training for twenty surveyors and engineers, including classroom and at-sea instruction. The Octopus F180 was selected by Fugro Survey after lengthy and intensive trials which established it as a credible and cost-effective solution for precision attitude and position data, ideally suited for multibeam survey. Providing high accuracy pitch, roll and heave data, together with inertia-aided position and heading, the F180s will be used in conjunction with Fugro's Reson multibeam sonar. With applications ranging from large vessel deepwater survey... (read more)

First Bluetooth Echosounder

The SonarMite Echo Sounder is the result of nearly two years research and development resulting in a series of equipment designed around the WinSTRUMENT concept and using the latest portable computers, integrated with new measurement technologies. The SonarMite extends the idea of a rugged design and minimalist interface to produce a 'Blue Box' system in which the user interface is provided by integrated software running on a portable computer connected via a Bluetooth link. The use of wireless technology enables the instrument to be waterproof and capable of use in a hostile environment, while the more sensitive computer features may... (read more)

AC-ROV Concept Vehicle

Ac-cess and their engineering partners at All Oceans (UK) have been researching, developing and testing materials and components leading to development of the AC-ROV concept video camera and sensor platform. This has six thrusters, all identical, to give the operator all the viewing control that will ever be needed. Four full-bore vectored horizontal thruster units give equal forward, sideways and pan control, whilst two vertical units give powerful up, down and pitch control. A one handed (left or right) 5-axis controller makes for a very simple and versatile operator interface. Flight Freeze is a further feature that may be selected,... (read more)

New Ball Joint Monitoring System

Nautronix delivered the first of a new system to its customer GlobalSantaFe for its vessel, Glomar Arctic III. The new Ball Joint Monitoring system integrates data from the Nautronix USBL positioning systems, in this case a RS914, and vessel data to provide a complete monitoring system. The system meets requirements put on GlobalSantaFe by their customer to provide continuous monitoring, logging and alarm capabilities for the lower ball joint, and related vessel data. The system also reads vessel pitch, roll and heave information, all of which is displayed and logged. The system also provides full monitoring capability and to view... (read more)

IXSEA to Introduce SAFE HEAVE

IXSEA introduces features with OCTANS III, a complete firmware and hardware redesign of the renowned through the industry motion sensor and gyrocompass Octans. SAFE HEAVE, Self-Adaptive Filtered Estimated Heave, is a dynamically tuned new heave filter concept that can assess heave parameters in true real time. As a result, not only the behaviour of the heave filter is always optimal, whatever the conditions and whatever the size of the vessel but also it does not require any set-up from the user. Using the latest progress in mathematical techniques, SAFE-HEAVE is particularly well adapted to changing swell conditions like harbour waves,... (read more)

EASYTRAK

Applied Acoustic Engineering has announced the full scale launch of their new Ultra-Short Baseline (USBL) tracking system, first seen at Oceanology International 2004. The UK based company has designed EASYTRAK as an economical solution for tracking a variety of targets including ROV’s, towfish and divers. EASYTRAK is compatible with all of Applied Acoustics’ transponders, with the added versatility of being able to track most other makes. 94 standard frequencies are pre-programmed into EASYTRAK, with the facility to set up an additional 4 user defined channels. A built in pitch roll and heading sensor has been added for automatic position compensation,... (read more)

New Parametric Sounder from Atlas Hydrographic

Atlas Hydrographic has introduced a new parametric multibeam sub-bottom profiling system, Parasound DS-3. The highest performance parametric system of its type presently available, it provides very precise high-resolution sub-bottom and water column data from 10m to full-ocean depth. Parasound DS-3 is capable of sediment penetration in excess of 200m while sampling data at up to 50 kHz frequency at all depths down to 10,000m. Digital pulse modulation ensures optimum signal-to-noise ratios, with Chirp and Barker code modulations as standard features and customised pulse modulation also available. A multi-pulse function permits transmission and receipt of up to 13 self-contained pulses within... (read more)
