Spectacular Positioning for MBARI Epedition

ROV tracking technology supplied by Sonardyne Inc. in Houston, USA to the Monterey Bay Aquarium Research Institute (MBARI) provided performance during an expedition to study recently discovered deep sea hydrothermal vents in the Gulf of California. Installed on MBARI’s Western Flyer research vessel, the Ranger 2 USBL system was used to track the position of the ROV Doc Ricketts as it dived down 12,500 feet (3,800 metres) to the seafloor and flew around the Pescadero Basin vent field, collecting video and samples for analysis. Despite the challenging conditions created by the vents spewing out super-heated seawater and suspended solids, the... (read more)

Centimetre-level Offshore Positioning Service

Fugro, headquartered in The Netherlands, has introduced a further advance in the field of GNSS augmentation with its high-accuracy G2+ service, designed to benefit offshore operators around the globe who require positioning and measurement accuracy at centimetre level. G2+ is an enhancement of Fugro’s G2 service (based on GPS and GLONASS) and utilises highly advanced GNSS augmentation algorithms developed in-house by its leading GNSS augmentation experts. The code and carrier-phase signals transmitted by GPS and GLONASS satellites are monitored globally by Fugro’s worldwide network of reference stations. These observations are processed centrally in real-time using the company’s proprietary algorithms to... (read more)

Dredge Efficiency and Precise Positioning

Integrating Dredging and Hydrographic Techniques
Dredgers involved in mining for (precious) minerals and metals often work in an inland dredging pit. Dredgers float in a ‘wet environment’ where the surrounding water is used as transport medium. The fact that the minerals are mostly covered in various sediments is one of the biggest problems in mining them. This article describes some of the techniques used in these dredging operations and illustrates the importance of integrating techniques and information. Most minerals, like rutile and zirconia, are to be found on top of a layer of clay with the highest concentrations found closest to it. Pewter is mostly... (read more)

Underwater Positioning Systems and Transponders

Kongsberg Maritime has launched during OTC a new range of acoustic underwater positioning systems and transponders, designed to harness the power of 'Cymbal' signal processing protocol whilst also being backwards compatible with the HPR 400 protocol and analog transponders. Other systems on display at OTC include HiPAP 501/451/351/351P, which are the second generation acoustic underwater positioning system offering improved position accuracy, longer range capability and faster data telemetry.  The new cNODE series of transponders consists of three models: Maxi - a full size transponder with large battery capacity, floating collar and release mechanism, and long life operation, designed primarily for...

Workshop Success Influences Future of Dynamic Positioning

Sonardyne International, in conjunction with Guidance Navigation and Veripos, UK, recently held a one-day user workshop focusing on the latest advances in Dynamic Positioning (DP) reference sensor technologies. More than 50 industry experts from a wide selection of companies gathered in Houston, USA, to review current Position Monitoring Equipment (PME) solutions and to discuss the industry’s future requirements. Significant focus was given to the integration of inertial technologies with acoustics, GNSS, laser and radar sensors, examining practical experience and real world examples whilst discussing opportunities for DP integration that would improve performance, increase availability and reduce risk. Other discussions throughout... (read more)

NovAtel Launches GNSS+INS Positioning Device

NovAtel, Canada, has recently added the IMU-ISA-100C as an Inertial Measurement Unit (IMU) option to its SPAN GNSS+INS line of positioning products. The IMU-ISA-100C is a near navigation grade IMU for platform stabilisation, general purpose navigation, photogrammetry, remote sensing and ground mobile mapping applications. Commercially exportable, the IMU-ISA-100C integrates easily with a NovAtel SPAN capable receiver to provide a tightly coupled 3D navigation solution. Offering customers continuous position, velocity and attitude (roll, pitch and azimuth) measurements, a SPAN system is stable and available even through periods when satellite signals are blocked or unavailable. With the IMU-ISA-100C, customers will receive near... (read more)
