Sonardyne Equips Brazilian Research Vessel

Ultra-Short BaseLine (USBL) positioning technology supplied by Sonardyne Brasil Ltda.The 64-meter-long vessel, which is operated by the University of São Paulo, undertakes research projects spanning global climate change to biodiversity in Brazilian waters. It will be equipped with a Sonardyne Ranger 2 USBL high precision acoustic positioning system to enable the Alpha Crucis’ 21-strong science team to precisely track their instruments and sensors to beyond 7 kilometers.Ranger 2 accurately tracks the position of subsea targets by precisely measuring the range and bearing from a vessel-mounted

. Specific tasks will include ensuring public safety with regard to the Boone Hydroelectric Dam, maintaining healthy waterways through the monitoring of water quality and preserving history through the recovery of Civil War-era UXO. Before the launch and operations, each team must complete Explorer, Ranger, Navigator and Scout challenges.The first team from England to qualify for the prestigious MATE ROV competition, Avalon Underwater Robotics, comprises of 17 multidisciplinary students from the Faculty of Engineering.

depending on the system options selected. These options include instrument configuration, transmission of state of health and triggered event or snippet data transmission at up to 9,000 bps.6G-inside capability also means that Aquarius is compatible with a range of other Sonardyne technologies, including Ranger 2 Ultra-Short BaseLine (USBL) positioning and telemetry, as well as its unmanned surface vehicle (USV) GPS-Acoustic payload box and Tsunami Detection System.Both companies have global reputations for provision of class-leading technology to academic, public, governmental and private organizations

Center.The MATE ROV Competition requires students to apply math, electronics, engineering and physics skills from the classroom toward solving problems based on real-world workplace scenarios. The competition challenges students from K-12, community colleges and universities within four levels (EXPLORER, RANGER, NAVIGATOR and SCOUT) to design, build and test underwater robots to complete specified, simulated real-world missions. They also must organize themselves into mock companies, an exercise that encourages them to develop entrepreneurial thinking and business and project management skills, while spurring

Teledyne Introduces New ADCP

Building upon the 20-year success of its Long Ranger Acoustic Doppler Current Profiler (ADCP), Teledyne RD Instruments (TRDI) announces the launch of its next-generation long-range ADCP, the Pinnacle 45.Rated to a depth of 2,000 meters, the 45 kiloHertz phased array Pinnacle ADCP delivers a 1,000-meter current profiling range with a decreased size and weight, a game-changing field-swappable system configuration for real-time or self-contained applications, independent or interlaced long-range and high-resolution modes, as well as many other innovative new features and product enhancements.The Pinnacle

The capability to plug in other navigation sensors to aid the AUV’s position was also critical and a second upward-looking Syrinx DVL is being incorporated to provide tracking on the underside of the ice. A2KUI will also be equipped for acoustic tracking using Sonardyne’s Ranger 2 Ultra-Short BaseLine (USBL) system, which is fitted to the UK research vessels RRS James Cook, RRS Discovery and the new polar research vessel RRS Sir David Attenborough.”Dr Alex Phillips, Head of Marine Autonomous Systems Development, at the NOC, says, “The development of Autosub2KUI

the transmission and reception of acoustic signals from the surface to an ROV. In a farm with up to 200,000 fish in any one cage, it has been thought that this could pose significant challenges for some acoustic based systems.In the trials, at the Korsneset SINTEF ACE site near Trondheim, Norway, a Micro-Ranger 2 Ultra-Short BaseLine (USBL) positioning system was used to track an Argus Mini ROV through a pen containing an estimated 150,000-200,000 salmon. Micro-Ranger 2 is Sonardyne’s latest USBL positioning system, designed for users with no previous experience of USBL equipment. It features a small

The Fusion 2 system works through Sonardyne’s Navigation Sensor Hub (NSH), which also supports the company’s Ranger 2 USBL system, so users will need fewer systems in their inventory and on board their vessels

array comprised seven full-depth moorings. Initially, each mooring was topped with an uplooking ADCP to monitor strong flows in the upper 350 m. Peak speeds were almost 2 m/s. In a later deployment, moorings near the core of the Current were terminated deeper. They carried an uplooking 75 kHz Long Ranger ADCP to measure currents in the upper 500 m.The Current was about 200 km wide and reached 3000 m depth. The water transported was 84 million cubic meters per second. A similar discharge was reported for the upper 2000 m of the Gulf Stream where it leaves the U.S. coast.In addition to quantifying
