    Opis:
    A watch officer in sailing a ship uses many kinds of navigational information to prevent marine disasters. Especially in coastal sea area such as narrow bay or port, many ships crowds and marine disasters tend to occur more often. In these regions, effective presentation of variety navigational information is very important. On other hand, a car navigation is very effective in road traffic, However, it is not used almost in sea traffic. Our objective in this paper is to apply a car navigation to ship sailing. Also, a marine navigation system proposed by us was compared with a car navigation system. In this study, authors tried some ways of utilizing car navigation technology for the sea. To improve navigational security and safety, we investigated whether car navigation systems could be applied to marine traffic. The applicability was evaluated through several comparisons of our navigation assistance device using GIS.

    21st century challenges
    Opis:
    For nearly the entire post-World War II period, naval and air navigation relied primarily on ground-based radionavigation systems. However, the spontaneous development of satellite systems gradually led to their disappearance. They are currently used partly in air operations and marginally in maritime navigation in some areas around Asia, in Russia and in the Middle East. However, at the beginning of the 21st century, the threat of effective interference with satellite systems began to be raised, which led to an increased interest in restoring or upgrading ground-based systems as backup systems in the Western world. In this context, the approach of Russia is interesting, as it is associated with the vast majority of deliberate GPS interference. There are reports in the world literature that various ground-based radionavigation systems operating in Russia are still observed. The article analyses, on the basis of the few available sources, information on the ALFA system, about which the least is known, and there are many indications that it is ready for use.

    Opis:
    The purpose of this study was to ascertain the level of academic performance in Auxiliary Machinery 2 subject and navigational trip among marine engineering students at maritime university, specifically JBLFMU-Molo, Iloilo City, Philippines. It further aimed also to determine the relationship of the two variables. The researchers used the quantitative research method and employed the descriptive statistics for the analysis of data among the randomly selected participants of the present study. The statistical tools were frequency, mean, and Pearson’s r. To come up with the data needed for this study, the questionnaire – checklist on “Navigational trip” was developed by the researchers. Results revealed that as an entire group, the level of academic performance was “excellent” and the navigational trip was “moderately satisfactory” among marine engineering students. The correlation between navigational trip and auxiliary machinery 2 subject was “positive and significantly correlated.”

    Opis:
    NaAVIC, is a free and downloadable Electronic Chart System app specifically developed for boats of all sizes looking for safe and reliable professional navigation functionality on mobile devices and/or laptops. The app offers a range of features to make navigation easy and reliable, delivered through a clear and intuitive interface designed specifically for navigating at sea. The capabilities cover the range of essential features needed to maintain safety and situational awareness. Separate processes for download and update of the electronic chart data is not required because data is streamed in real-time from a cloud based open source database. The data is supplied to NaAVIC from Nautilus Cloud, a cloud based infrastructure designed for Marine Data, Solutions and Services for Government Organizations, Commercial Industry and Consumers. Nautilus Cloud is a “cloud native” approach and leverages high quality, open source components as its base technology. It uses open standards throughout to build a low-cost system which is flexible and has a much greater degree of interoperability with pre-existing components. A key feature of the Nautilus Cloud platform is the expansion of data holdings into a much wider family of related geospatial data products including the S-100 framework, harmonized metadata, raster and real-time sources. In essence, NaAVIC can operate on real-time and up-to-date information from charting agencies without a separate updating process. This enables the integration of real-time tides, weather, currents and other oceanographic information.

    Opis:
    The paper presents design and realization of computer decision support system in collision situations of passage with greater quantity of met objects. The system was implemented into the real ship electro-navigational system onboard research and training ship m/v HORYZONT II. The radar system with Automatic Radar Plotting Aid constitutes a source of input data for algorithm determining safe trajectory of a ship. The article introduces radar data transmission details. The dynamic programming algorithm is used for the determination of safe optimal trajectory of own ship. The system enables navigational data transmission from radar system and automatic determining of safe manoeuvre or safe trajectory of a ship. Further development of navigator’s decision support system is also presented. Path Planning Subsystem is proposed for the determination of global optimal route between harbours with the use of Ant Colony Optimization algorithms.

    Opis:
    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.

    Opis:
    The paper presents the processing of EGNOS integrity data received either directly from the satellite network or the Sisnet internet relay. Relationship between the individual frames in EGNOS messages has been described. Usefulness of these data was indicated by the three examples. In the first example data form EGNOS was used to compare integrity parameters and the calculated position error. In further examples the simulated position with error and calculated integrity parameters were implemented together. The results were presented in two ways: with use of dedicated program which presents only ship contours (the one not covering GNSS uncertainty and the one covering this uncertainty called Marine Vessel Protection Area) and as a layer in existing ECDIS.
