Opis:
Virtual electronic aids to navigation are being introduced into the present short range aids to navigation system in the form of Automated Information System radio-based aids. Research is also underway into the development of their equivalents for use in regions that feature hostile environments, are poorly charted and lack any infrastructure whatsoever to support traditional or radio navigation aids. Such aids are entirely virtual in nature and exist only as a digital data object that resides within an electronic navigation chart for display to mariners through an Electronic Chart Display and Information System. They are at present experimental in nature, and are not intended to replace existing physical or radio-based aids to navigation. Results of research are described in terms of fulfilling traditional navigation aid functions and the development of new functions that are only possible using virtual aids. Their advantages in design and implementation are highlighted, as are their limitations and shortcomings as compared to present methodologies. Notable, however, is the approach used to overcome limitations and shortcomings by considering attributes of the physical environment to ensure their proper location and display of correct characteristics. Such an approach is unique in the modern world, yet it emulates ancient methods of navigation using known landmarks and terrain features.

Opis:
This paper presents a comparative analysis of manoeuvring patterns through the fairway which is marked with physical and virtual Aids to Navigation (AtoN). The impact of V-AtoN environment on decision-making and on consequent manoeuvres has never been studied in such a way. The results published in this paper were obtained using TRANSAS Navi Trainer 5000 and TRANSAS ECDIS 4000 simulators where 12 deck officers with at least 5 years of sea service participated. The results of the study indicate that there is a significant difference in manoeuvring patterns between the two environments. In case of virtual environment, more intense drift angles, ROTs as well as XTDs are observed. The paper demonstrates significant impact of virtual environment on behaviour of OOW.

Opis:
The Automatic Identification System (AIS) provides situational awareness for vessels at sea. AIS has a number of known security vulnerabilities that can lead to a several types of attacks on AIS, including the ability to create ghost vessels, false warning or meteorological messages, or bogus virtual aids-to-navigation (AtoN). A number of methods, with varying levels of complexity, have been proposed to better secure AIS and, indeed, emerging AIS protocols will implement some of these mechanisms. Nevertheless, little has been done to secure the current standards, which will remain in use for some time. This paper presents Protected AIS (pAIS), a demonstration of capability implementation using public-key cryptography methods to address several AIS security vulnerabilities, maintain backward compatibility, and be able to interoperate with non-pAIS devices.

Opis:
The risk level of the Aids to Navigation (AtoNs) can reflect the ship navigation safety level in the channel to some extent. In order to appreciate the risk level of the aids to navigation (AtoNs) in a navigation channel and to provide some decision‐making suggestions for the AtoNs Maintenance and Management Department, the risk assessment index system of the AtoNs was built considering the advanced experience of IALA. Under the Formal Safety Assessment frame, taking the advantages of the fuzzy comprehensive evaluation method, the fuzzy‐FSA model of risk assessment for aids to navigation was established. The model was implemented for the assessment of aids to navigation in Shanghai area based on the aids to navigation three‐dimensional simulation system. The real‐time data were extracted from the existing information system of aids to navigation, and the real‐time risk assessment for aids to navigation of the chosen channel was performed on platform of the three‐dimensional simulation system, with the risk assessment software. Specifically, the deep‐water channel of the Yangtze River estuary was taken as an example to illustrate the general assessment procedure. The method proposed presents practical significance and application prospect on the maintenance and management of the aids to navigation.
