Ice And Ship Safety Data Network To Launch In 2022
A newly established consortium is going to develop a network for low Earth orbit satellites delivering ice chart data to ships at sea. The new system will use the new AIS VDES radio data exchange system, to increase safety at sea.A new research project called MARIOT (Maritime IoT) is going to develop a low Earth orbit satellite network based on the new VDES (VHF Data Exchange System) technology. The consortium behind the project is headed by the Danish satellite operator Sternula. The satcom developers GateHouse, Space Inventor, and Satlab as well as Aalborg University, and the Danish Meteorological Institute also participate in the project which will initially focus on the need for improved communication and navigation services in the Arctic Ocean.VDES technology is the second generation of the Automatic Identification System (AIS). Today, the AIS standard is used to monitor marine traffic by more than 200,000 ships. However, AIS has a limited reach of only 30 nautical miles and is also limited to transfer on only certain types of data. VDES will enable global connectivity through satellite networks as well as efficient transfer of more data types.  “VDES offers a faster and more efficient data connection compared to other satcom services on the market, and after the VDES standard was assigned global radio frequencies last year, we now have the opportunity to launch the first global VDES network improving navigation services and security for ships sailing through treacherous passages, Per Koch explains.Besides shipping companies operating in the Arctic Ocean, the VDES network is also relevant for maritime security and navigation services, e.g. for sailing directions and coastal monitoring, and can also be used by the maritime industry to monitor marine engines and critical equipment on board.The contribution from GateHouse is mainly related to data communication. More specifically by ensuring that data can be communicated to and from the individual satellites to the ground station. This include inter-satellite capabilities and advanced algorithms for data routing in satellite constellation.GateHouse, Space Inventor, and Satlab will develop the hardware and software components for the project while Aalborg University-based on its extensive experience with launching smallsats will contribute with technology and expert knowledge. The Danish Meteorological Institute will participate with its ice chart service, which is in development and will be tailored to the VDES network. The MARIOT project will be managed by Sternula and is sponsored by the Danish Innovation Fund.Press release from MarineLink.com
