SEERAD system to improve sea rescue

Fraunhofer FHR has announced a new project with FH Aachen and Raytheon Anschütz to develop a cost effective sea rescue radar to be used to locate individual persons or small boats over long distances.

{mprestriction ids="1,2"}Fraunhofer says that the SEERAD system will involve small transponders, located in life jackets for instance, that reflect the signals of future maritime radars, which then receive these signals using an extension module.

The project is funded by the German Federal Ministry of Education and Research (BMBF), and is based on the application of harmonic radar technologies.

With conventional maritime radars, Fraunhofer says that it can be difficult to detect small objects at sea in increasing swells because their reflections can barely be distinguished from the uneven surface of the water. For SEERAD, transponders the size of a bank card which can be integrated into life jackets, safety devices, or water sports equipment could return the signal of the maritime radar with twice its frequency.

Extending future maritime radars with a harmonic radar module that sends signals in the S-band and also receives them with twice the frequency in the C-band would allow these reflected signals to be recognised and locate a person who has fallen into the water, the researchers said.

The system’s range will reach up to one kilometre using passive reflectors only (without battery) and up to more than ten kilometres using active transponders powered by a water-activated battery. These tags can be produced at prices of less than ten Euro per piece, the companies said.{/mprestriction}

  • Fleet Xpress chosen for Nekton ocean research project

    Inmarsat’s Fleet Xpress has been chosen to provide the connectivity backbone enabling images captured by the deep ocean research institute, Nekton from the floor of the Indian Ocean to be transmitted to audiences worldwide.

    The Nekton Institute is an independent, not-for-profit research institute working in collaboration with the University of Oxford. It aims to accelerate the scientific exploration and protection of the oceans.

    The maritime high-speed broadband service provided connectivity to relay broadcast images from Nekton’s submersible off the Seychelles last year. Along with Associated Press, Sky News and Sonardyne, it won the 2019 IBC Innovation Award for Content Distribution and the 2020 Royal Television Society News Technology Award.

    The 2020 mission entitled ‘First Descent – Midnight Zone’ will include a 35-day long voyage starting in mid-March exploring biodiversity around the Maldives, Seychelles and the High Seas. Video, audio and - for the first time - data will be transmitted from the deepest parts of the High Seas in the Indian Ocean to the research vessel Pressure Drop, then relayed via Fleet Xpress to marine science projects focusing on sustainable oceans.

    “The ocean is a key part of each Maldivian,” said president Ibrahim Mohamed Solih of Maldives. “71 per cent rely on the ocean for their primary source of income. We have committed to a 5-year initiative to advance ocean protection and sustainably develop the blue economy. This expedition will help us establish the long-term sustainability of our economic growth, livelihoods and jobs through establishing marine protected areas to build ocean resilience”

    Deep ocean locations are often also the farthest from shoreside support. For high-tech research vessels monitoring and managing subsea activities today, reliable connectivity is becoming an operational as well as a safety need.

    “For all practical purposes, until now it has not been possible for research vessels in remote seas to transmit large quantities of data back to base in real time, let alone stream images suitable for high-definition TV broadcast,” said Peter Broadhurst, senior vice president, Inmarsat. “Nekton’s decision to work with Inmarsat has changed that.”

    Pressure Drop’s video-streaming capability has already been proven through her role in the ‘Five Deeps Expedition’, supporting the world’s only manned submersible able to descend to full ocean depth (11,000m). For its new mission, data from submersibles will feed into the 2022 Indian Ocean Summit, where Seychelles and Maldivian governments, and ‘First Descent’ partners seek to create a sustainable management plan for 2,000,000km2 of ocean.

    Part of the Pressure Drop project also sees Inmarsat installing Fleet Data, the maritime industry's first secure IoT platform, which extracts data from sensors and uploads it to a secure central cloud-based database for easy access with no additional airtime cost. Its use will enable the first-ever transmissions of water chemistry and geophysics datasets.

    Fleet Data will also allow scientific research to be shared onto an open source platform, with processed datasets made available so that registered marine scientists around the world can participate in a virtual Hackathon to interrogate data and publish findings within two weeks. All datasets will be blockchain-coded to ensure security, transparency, and decentralisation.

    “One of the biggest issues is that it can take months or even years to publish data analysis, by which time data may have less relevance and application. By using Fleet Data we can publish data in an instant via an Inmarsat API: this is ground-breaking for marine science and could accelerate the analysis and publication of ocean data,” said Oliver Steed, chief executive, and Nekton.

    Inmarsat’s yachting partner YachtProjects designed, installed and commissioned Pressure Drop’s management and communications systems, including ECDIS, CCTV and open port capability.

    Nekton’s research, sampling and survey technologies fully integrate with shipboard systems, with the YachtProjects’ Seawall package controlling the shipboard network and shaping bandwidth and streaming, with the terminal hardware provided by Intellian Technologies.
