Ocean Aero to Supply Vehicles for Homeland Security

agreement to deliver a variety of the company’s autonomous underwater and surface vehicles (AUSV) models to the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) for a research, evaluation and testing program.Ocean Aero will deliver a mix of its Navigator and Discovery models and working closely with DHS and other program participants—the U.S. Coast Guard (USCG), U.S. Customs and Border Protection (CBP), The University of Southern Mississippi, the U.S. Naval Research Laboratory (NRL), and Cherokee Nation Strategic Programs, LLC.

Here, the DVL transducers, the inertial motion unit and the depth sensor are housed together, offering a number of advantages. For instance, the individual DVL beams are used to update the INS solution while also computing a DVL velocity vector. The result is a more accurate and robust

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.

Cook was not an exploiter,” said Lindblad. “He was a true explorer with a variety of remarkable qualities,” he enthused, continuing, “Cook was a great navigator, curious and deeply concerned about the future of places he visited, like Tahiti or Australia. He worried about what would happen to these pristine areas when westerners bringing disease and destruction would come and settle. Places he visited had generally happy social structures, far more so

ASV BEN (Bathymetric Explorer and Navigator) is a custom prototype built by SV Global Unmanned Marine System for University of New Hampshire’s Center for Coastal and Ocean Mapping. ASV BEN has a state-of-the art seafloor mapping system that can map depths reaching 650 feet. (Photo: Ocean Exploration Trust)

Searching for Shipwrecks

they would discover new shipwrecks and natural features such as sinkholes, fish habitats, and interesting geological formations.During the two-week expedition, researchers mapped areas within the sanctuary with a multibeam sonar system aboard autonomous surface vehicle ASV BEN (Bathymetric Explorer and Navigator) from University of New Hampshire’s Center for Coastal and Ocean Mapping. BEN is a state-of-the-art robotic vehicle that looks like a small yellow boat. Unlike most boats, though, it doesn’t carry people; instead, it is piloted by crew members back on shore. Using sonar and GPS, BEN

MATE ROV Competition Planned in Tennessee

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 innovation

Teledyne RDI Rolls Out New DVL

Teledyne RD Instruments (TRDI) has launched its next-generation Doppler Velocity Log (DVL), the Tasman DVL.In 1995, Teledyne RDI designed and manufactured the industry’s first DVL, the Workhorse Navigator, aand has since delivered thousands of units globally to provide precision onboard navigation for subsea and surface vehicles.The new 600/300 kilohertz Tasman DVL, with its reduced size, weight and increased range, has been designed to supersede the Navigator with increased accuracy, and an industry first innovative field replaceable phased array transducer design, the manufacturer said.

that highlighted Jet City: Aircraft, Earthquakes, and Energy, 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
