    Opis:
    Although SOLAS still requires nautical paper charts on pleasure crafts, more and more sailors prefer navigating digitally. What are the impacts on their spatial abilities? We conducted a field experiment at the Baltic coast and two simulator experiments with altogether 40 sailors. Participants plotted and/or piloted routes either in the classic manner on paper charts or digitally on an ECS. We assessed the situation awareness, the cognitive map, and (for the simulator only) the wayfinding with and without the navigation media. We found that digital navigation significantly impaired the cognitive map. Its impact on situation awareness, however, depended on previous navigation habits: Only sailors who used their paper charts regularly and actively benefitted from the ECS. We concluded that ECS navigation with its high level of automation lastingly alters spatial perception at sea and impairs orienting. With the vulnerable electricity supply on sailboats, this is a safety issue for shipping.

    Opis:
    High level solution S4 of the IMO E-navigation Strategy Implementation Plan provides integration and presentation of available information in graphical displays received via communication equipment. At the same time, the problem of the correct application of digital selective calling (DSC) operational procedures in navigation practice has existed since the introduction of the GMDSS and requires a solution. This problem may be resolved on the base of integration maritime navigation and radiocommunication equipment. The article proposes approach for practical realization of this integration by implementing a SMART (specific, measurable, assignable, realistic, and timely) DSC interface within S4. Using this approach the practical realisation integration of AIS – DSC – Information display was implemented. It makes possible implementation of user-friendly human-machine interface (HMI) for navigator. An experimental prototype of communication graphical interface is designed, which allows effective decision-making on radio communication control/monitoring. The use IEC 61162-1/2 (Maritime navigation and radiocommunication equipment – Digital interfaces) data transfer provides standard inter-module connections and eliminates the negative impact of the equipment diversity from different manufacturers by means uniform HMI implementation.

    Opis:
    Digital selective calling (DSC) has a certain drawbacks, which have led to the fact that it is practically not used in address radio communications. Attempts to improve it only within the DSC system itself did not lead to any noticeable results due to neglecting of real user needs. The article proposes an approach to improve the user interface of DSC based on the integration of VHF MF/HF DSC equipment with the INS within the three main outputs of strategic direction of e-navigation development related to the integration of communication and navigation systems and, in particular, the S-mode. This approach allows us to significantly simplify the DSC user interface, based on the standardization of DSC integration for all three VHF MF/HF communication sub bands. For implementation such standardization an additional inclusion into the integration a satellite AIS system should be done. The feasibility of the proposal is supported by the existence of relevant IEC standards and IMO documents. The possibility of increasing the cyber security level of AIS messages in this interface is also considered.

    Opis:
    Standard ECDIS configuration doesn’t foresee interaction with Digital Selective Calling (DSC) device. We propose a reasonable way to eliminate the drawbacks of existing VHF radiotelephony using DSC and obtain new advantages in communication and navigation in the frame of existing conventional installations. The proposed innovation is based on ECDIS software updating and the interconnection to DSC equipment. ECDIS modernization would get rid a navigator of the routine procedures and handling with abstract data replacing them by understandable actions on ECDIS display. The proposed integration gives new abilities for smart addressed VHF/DSC communication by estimating the current navigational situation around the ship that is especially important in congested ports, waterways and poor visibility regarding human factor. The proposed modernization retains in operation all standard DSC and ECDIS functions and provides full compatibility with commonly used non-integrated equipment. Financial expenses to its implementation for ship-owner are minimal due to only software updating and standard cabling.

    Opis:
    Measurement of altitude traditionally made with sextant may be done with help of digital still camera. Factors influencing accuracy of this measurement done with help of such a device are described in the paper. Values of errors introduced by each of these factors are estimated basing on example technical data of typical digital camera. This analysis shows, which factors are the most important and if accuracy of altitude is sufficient for purposes of celestial navigation.

    Opis:
    Crowdsourced bathymetry (CSB) is relatively new concept of collecting bathymetric data. CSB can be defined as the collection and sharing of depth data (and metadata) measured and collected by non-traditional survey vessels equipped with navigation instruments, while maintaining their usual operations at sea. International Hydrographic Organization (IHO) has developed Guidance on CSB. This document provides framework for data collection, processing and information about data uncertainty. IHO has also developed model within CSB concept in order to make standardization of CSB data. The data collected using CSB may represent valuable supplement to the existing data collected by hydrographic survey. Despite this fact it is necessary to emphasize that CSB data cannot be used as official data. CSB data collection has also potential legal issues due to the character of sounding passage within territorial and internal waters of coastal states. This paper emphasized the differences between hydrographic survey and CSB. Advantages and disadvantages are analyzed with it's potential implication on safety of navigation. Due to the CSB data collection model limitations, development of bathymetric data collection model on national level is recommended.
