Sonardyne USBLs Installed on Brazilian Geoscience Vessels

Brazilian geoscience services company OceanPact Geociências has chosen deep water positioning technology from Sonardyne Brasil Ltda. to support its geophysical, geotechnical and environmental research operations across the region.Ranger 2 Ultra-Short Baseline (USBL) systems have been installed on board OceanPact’s research vessels Seward Johnson and Austral Abrolhos, both currently on hire to Brazilian oil major Petrobras. The systems will be used to precisely track the location of underwater equipment and sensor packages deployed from the ships, including seabed corers, towed sensors and

VideoRay ROVs Equipped with Sonardyne Positioning

VideoRay LLC and Sonardyne International Ltd. have been working together to demonstrate enhanced remotely operated vehicle (ROV) operations through integration with positioning systems.UK-based underwater positioning specialist Sonardyne initially integrated Micro-Ranger 2 Ultra-Short BaseLine (USBL) technology with VideoRay’s Mission Specialist Technology for ROVs in 2018. Since then, the systems have been deployed together in a range of applications from aquaculture to mine countermeasures operations.Sonardyne’s Micro-Ranger 2 USBL system is designed for shallow water tracking of divers

Survey Vessel Launched for Geo Plus

Dutch shipbuilder Royal Niestern Sander said it has launched a new vessel currently under construction for hydrographic survey firm Geo Plus BV. The newbuild, to be named Geo Ranger, is due to be christened and delivered this summer.The contract for the construction of the hydrographic research vessel Geo Ranger was signed by the builder and Geo Plus in April 2019.After the start of construction in September 2019, the ship was transported in early February from the construction hall to the quay side to prepare for the launch, which took place on March 7.The ship (yard number 864) was designed together

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. Representing Mechanical Engineering, Automatic Control and Systems 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

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

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
