been working on automated operations, such as auto docking, where the ROV pilot can direct the ROV to move autonomously to a docking point by moving a cursor on the screen, without any intervention on the joystick. It is the machine vision recognition software tied into the control and inertial navigation systems that allows it to perform those tasks consistently. This is still an emerging technology, and it takes a little time to dock autonomously. The reality today is that a really good pilot could do it quicker, but not necessarily consistently and repeatedly. The technology is evolving, but I expect

iXblue Expanding in Australia

Navigation, positioning and imaging firm iXblue said it is expanding its local capabilities in Australia. In 2019, it will focus on developing the company’s local expertise in Inertial Navigation Systems for both defense and civil markets.“We have been present in Australia for over 10 years with a dedicated Brisbane-based team of highly qualified engineers, hydrographers, geophysicists, program managers and equipment sales staff,” said Fabien Napolitano, CEO of iXblue. “Australia being a key market for iXblue, it was only natural for us to expand our capabilities in the region.

system, the Gaps system is equipped with a pre-calibrated USBL (Ultra Short Base Line) antenna and offers very high-precision geo-referenced positioning performance, particularly in shallow waters and in noisy environments. Its telemetry function also allows for the recalibration of the inertial navigation systems (INS) on board the underwater vehicle thanks to an acoustic communication link, as well as for the command and control of the AUV. The broad opening of its 3D antenna, up to as much as 200 degrees, also gives it unrivaled capacity in terms of horizontal tracking, enabling the system to cover

Mapping the Future

system architecture of autonomy for planning, analysis and execution is similar for AUVs and USVs but there are differences in sensors and functions because of the environment. Lack of GPS and radio communication are fundamental constraints to AUVs that are solved by acoustics and aided inertial navigation systems.USVs need advanced scene analysis and route planning to navigate safely in areas with maritime activity. There are significant thresholds to sufficient functionality and robustness of the individual systems. The most critical phases of the combined USV-AUV operation are launch and recovery

software operated aboard the vessel is a combination of open-source robotic operating systems and software developed by engineers Roland Arsenault and Val Schmidt at the center to tailor BEN’s behaviors for hydrographic seafloor survey. BEN is outfitted with state-of-the-art sonar and navigation systems to meet the seafloor survey requirements for nautical charting and safety of navigation. The navigation system provides exact positioning and attitude while BEN plows the ocean’s surface, while the sonar paints a swath of measurements below and to the sides of the vessel.On Saturday,

Greensea and ION have already collaborated to integrate ION’s optical magnetic heading sensor into Greensea’s INSpect navigation system to dramatically improve subsea vehicle navigation accuracy in remote GPS-deprived environments.“I am really pleased with how quickly we

University of Limerick Buys ROV for Renewables Research

Digital Single Market and Data Protection, Pat Breen TD.The Comanche ROV was selected due to its high thrust-to-drag ratio enabling it to operate in strong currents, typical conditions for the offshore renewables industry. The ROV is equipped to a high specification with precision positioning and navigation systems, camera and lighting systems and sonars. The systems will be used as a test bed for research to develop capabilities for inspection, maintenance and repair work on Marine Renewable Energy (MRE) infrastructure in the challenging strong wave and current conditions at MRE test-sites and offshore

The unique acoustic undersea environment is further compounded by the presence of a contoured, reflective ice canopy when submerged.   According to Pitts, operating in the Arctic ice alters methods and practices by which submarines operate, communicat

I’ve developed the propulsion, communications, and navigation systems and we are working with customers to understand the kind of data that they want. We’ve had a great response from all different sectors, and we expect to have something in the water by June 2018,” explains Durrant.

However, due to the unique positioning system and imaging systems, it was still possible to perform an accurate cleaning of the hull. Fleet Cleaner uses innovative navigation systems in order to ensure a high quality hull cleaning, even in such conditions. With the cleaning of the Vlieborg, and recently also the hull cleaning of the Marcor bulk vessel in Rotterdam, Fleet Cleaner has introduced itself in Dutch ports as the new standard for in water cleaning

We’re building a ‘get me where I want to go’ system.”   Kinnaman said the engineering challenge is the relationship – how the operator is to use the tools that are behind the scenes – the inertial navigation systems, the autopilots, the mission planning systems and the sonar interfaces. The interface that delivers the operator’s requirements is really the hard part, and that’s the relationship.   For the DPD Greensea has a number of deliverables according to Kinnaman. “STIDD builds
