The completion of ECDIS mandatory implementation period on-board SOLAS vessels requires certain operational, functional and educational gaping holes to be solved. It especially refers to positioning and its redundancy, which represents fundamental safety factor on-board navigating vessels. The proposed paper deals with primary and secondary positioning used in ECDIS system. Standard positioning methods are described, discussing possibilities of obtained positions’ automatic and manual implementation in ECDIS, beside default methods. With the aim of emphasizing the need and importance of using secondary positioning source in ECDIS, positioning issue from the standpoint of end-users was elaborated, representing a practical feedback of elaborated topic. The survey was conducted in the form of international questionnaire placed among OOWs, ranging from apprentice officers to captains. The result answers and discussion regarding (non)usage of secondary positioning sources in ECDIS were analysed and presented. Answers and statements were elaborated focusing not only in usage of the secondary positioning system in ECDIS, but in navigation in general. The study revealed potential risks arising from the lack of knowledge and even negligence. The paper concludes with summary of findings related to discrepancies between theoretical background, good seamanship practice and real actions taken by OOWs. Further research activities are pointed out, together with planned practical actions in raising awareness regarding navigation with ECDIS.

The paper deals with two different approaches to orthodromic navigation approximation, the secant method and the tangent method. Two ways of determination of orthodromic interposition coordinates will be presented with the secant method. In the second, tangent method unit change of orthodromic course (ΔK) will be used.

Konieczność usprawnienia przewozów kolejowych w relacji wschód-zachód wynika z potrzeb rynkowych. Utrzymująca się w ostatnich latach tendencja do wzrostu wymiany handlowej pomiędzy krajami byłego Zwiaązku Radzieckiego i krajami daleko-wschodniej Azji (Chiny, Korea) z Europą Zachodnią wymusza potrzebę rekonstrukcji systemów transportowych i poszukiwania efektywnych rozwiazań. Szczególna uwaga zostaje zwrócona na transport kolejowy, który jest w stanie spełnić współczesne wymogi w zakresie jakości i bezpieczeństwa przewozów.
