EvoLogics Presents 'Tiny' Modems

the S2C T are capable of simultaneous tracking and reliable bi-directional data transmissions with advanced networking. The “tiny” modems are fully compatible with existing EvoLogics hardware and deliver a great performance in most challenging conditions.EvoLogics S2C spread-spectrum communication technology stems from bionic concepts and over the years evolved into a whole ecosystem of products. This includes several series of underwater acoustic modems, modular underwater positioning systems (USBL, LBL, SBL), as well as a framework for developers in both networking and hardware design.The

OceanAlpha Launches 5G Unmanned Vehicle

A 5G unmanned surface vehicle recently made its debut in Barcelona, Spain. The new boat was unveiled at the Mobile World Congress 2019, where fifth generation of mobile communication technology (5G) was the "hottest topic", said Chinese company OceanAlpha, who developed the new vehicle OceanAlpha 5G alongside developed by Ericsson and China Mobile.According to its developer, the unmanned "environmental smart vessel" is designed to help address the problem of water pollution by quickly and efficiently collecting water quality monitoring data, identifying the cause of the

agreement as an opportunity to offer a further step-change in the solutions provided to customers. BMT will bring 30 years of marine instrumentation design experience and extensive integration expertise to the working arrangement, while Sonardyne will provide access to subsea data logging and communication technology including its SMART low-power subsea sensors.The two companies said they are already working on proposals for major operators globally, which would offer significant cost reductions on existing systems, with longer periods between maintenance

Mapping the Future

to operate without assistance for months at a time and is the first of a new generation of craft that can truly operate independently. Built by British company Hushcraft, Sea-Kit, combined with the deep and rich expertise of the GEBCO-NF Alumni Team, the Hugin AUV and autonomy, positioning and communication technology from Kongsberg Maritime certainly has the potential to provide a new, more efficient way to map the oceans. Of course the other eight teams all have innovative new concepts to prove, making it impossible to predict the winner of the Shell Ocean Discovery XPRIZE. But we will find out soon

RTsys will also highlight its web interface RAISONNANCE, which enables users to check underwater measurements such as oxygen, turbidity, temperature, pressure and acoustics in real-time. The company will also demonstrate how its underwater acoustic communication technology is used across its portfolio. On-water Demonstrations On-water demonstrations will take place throughout the three-day Oi18 on several participating exhibitor vessels. Exhibitors taking part in these include Braveheart, Briggs Marine, iXblue, MS-Geotech Ltd, Norbit and R2Sonic. R2Sonic

Water Linked Launches Underwater GPS System

.” Water Linked’s Underwater GPS system is designed to operate in challenging environments such as shallow water within ports or fish cages for aquaculture, environments where existing conventional underwater positioning systems break down. While the development of GPS and communication technology has been a key enabler for a wide variety of above-water innovations in the past decade, both have been limited below the ocean surface. Water Linked’s new technology will open several possibilities, including the Underwater GPS system and, in the future, underwater wireless communication

features and coming up with new configurations. The latest and biggest “under the hood” update is S2C 2.0 - at Ocean Business 2017 in Southampton, UK, the team will proudly present this boost to the very core of EvoLogics’ product family, the patented S2C spread-spectrum communication technology. EvoLogics reveal the S2C 2.0 after extensive research: enhanced with dynamic carrier arrangement, the wireless technology’s cutting-edge modulation and demodulation techniques aim to set new standards for reliable data transfers in highly dynamic subsea environment.

solutions. S2CM-HS will be available with a cable-mounted transducer, offering more options for system integration, for example, into diver communication systems. The M-series is fully compatible with the company’s standard S2C R and S2C R USBL series that rely on the patented broadband communication technology, overcoming the challenges of dynamic underwater environment to deliver a great performance in various subsea conditions. M-modems are smaller and lighter than the standard EvoLogics R-series devices, but offer an uncompromised performance of the full-sized product line. www.evologics

sensor systems with a range of different sensors integrated. They will be deployed for 12 months continuous operation on the Arctic seabed and are fully self-contained, powered by battery packages and able to wirelessly keep contact with the surface through Kongsberg Maritime developed acoustic communication technology. “It is the first time that research is being done on the entire methane emission system from the seabed to the atmosphere. To measure these emissions we need a lot of instruments that are at the forefront of development,” said Benedicte Ferré, team leader at CAGE responsibl
