This article aims to investigate the contemporary challenges of electronic navigation and assess the appropriate amendments should autonomous vessel technology becomes widespread in the near future. Vessel control systems and maritime communication are essential and sending and receiving alarm signals is critical to contemporary ship navigation. Numerous location and shipping information systems, such as GPS, Loran-C, and Decca, have arisen in recent decades to improve navigational safety. Other systems, including VHF and Inmarsat, have been developed to enhance the efficiency of maritime communication on board and to transmit risk and safety-related data. Additionally, safe navigation requires systems like Navtex, EGS, DSC, Epirb, and others [1].

In the paper, the author attempts to isolate, clarify, systematize, and classify various types, models and kinds of electronic chart systems, operating nowadays on the shipping market, which are a perfect example of the use of GIS (Geographic Information System) technology in widely comprehended maritime and inland waterway applications, in particular tries to promote internationally standardized system ECDIS (Electronic Chart Display and Information System), its RCDS mode (Raster Chart Display System), as well as Warship ECDIS (WECDIS), and Inland ECDIS (I-ECDIS). In the paper the author presents the general classification of electronic chart systems taking into consideration the following criteria: international standards, certification by classification society, used data base, updating system and certification by maritime administration.

The maritime high speed craft navigators` ultimate aim has for decades been to safely and efficient navigate the vessel to its destination. The last decade an increased use of technology has arrived at the maritime ship bridge. The use of Electronic Charts and Integrated Navigation Systems has revolutionized much of the work of the navigator, with the aim of enhancing the safety of navigation. The amount of information has drastically increased, and the need for a proper information management and an efficient visual scan pattern has been identified. Looking to other industries this has been introduced with success, and in this paper the authors present a proposed scan pattern for the maritime navigator. The analysis is based on an eye tracking data set collected from simulator- and field studies on board the world’s fastest littoral combat ship.

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.
