Sažetak
This paper deals with the use of ECDIS for plotting position by using celestial bodies. Standard intercept method results in the line of position (LOP) which should be plotted on the navigation (paper) chart or a hand-made auxiliary diagram, where two or more intersecting LOPs indicate the position of the vessel. The navigation (paper) chart is more convenient for direct plotting of LOP than standard blank paper (auxiliary diagram), but the paper charts are being increasingly replaced by electronic chart systems, i.e. the ECDIS (Electronic Chart Display and Information System) that is recognized as an official paper chart equivalent. Accordingly, everything that can be plotted on the paper chart should be also available in the ECDIS. This includes plotting of the astronomical LOPs. Although most of today’s ECDIS systems do not support ephemerides nor the possibility of the direct LOP’s determination, the available functions of manual drawing of different symbols and objects, combined with ERBL function, enable graphical plotting of LOPs and, eventually, fixing the vessel’s position. In addition to the analysis of standard astronomical LOP plotting (for fix and running fix), this work also analyses the ways the ECDIS can assist in approximate position determination when only the azimuths of celestial bodies are known. Certain recommendations for future ECDIS improvements are given as well.
