MATE ROV Competition Planned in Tennessee

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

, which gave a nod to the location as this year’s competition theme.The competition has certainly evolved over the years – and not just in terms of numbers. About five years ago we added a fourth competition level or class called NAVIGATOR (the progress is now SCOUT – NAVIGATOR – RANGER – EXPLORER).Why was that done?We did this because, in 2008, we recognized that middle schools were the fastest growing population of competition teams. We certainly hadn’t tried to proactively reach that population. As a matter of fact, our MATE grant focused on community colleges and

Oceanscan Invests in Sonardyne Acoustics

International equipment supplier Oceanscan has added underwater acoustic positioning technology from Sonardyne International Ltd. to its rental fleet. The Mini-Ranger 2 Ultra-Short Baseline (USBL) vessel-based systems and Wideband Sub-Mini 6 (WSM 6) transponders have been acquired by Oceanscan following client demand for accurate and reliable underwater tracking technology to support their projects, especially in the growing offshore wind and shallow water hydrographic survey markets. Compact, portable and quick to install, Mini-Ranger 2 offers a standard operating range of 995 meters, extendable
