Standardization of interface for VHF, MF/HF communication using DSC within Itsintegration with INS in the framework of e-Navigation concept

Koshevyy V., Shishkin O.

593--596

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.

ECDIS Modernization for Enhancing Addressed VHF Communication

327-331

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.

Advantages of Preservation of Obligatory Voice Communication on the VHF Radio Channel 16

137--141

Channel 16 of the VHF radio band is the most commonly used way of communication between vessels. Alt-hough there are strict rules not to use it for routine communication, many officers neglect them. When Digital Selective Calling had been presented to the GMDSS system, it was no longer obligatory to keep a watch on channel 16, however, on the waters of the United States such an obligation is still in force. Officers find DSC system quite difficult to use so the European countries should revise their politics and consider restoration of obligatory watchkeeping on channel 16.

GMDSS as a Data Communication Network for E-Navigation

Korcz K.

TransNav : International Journal on Marine Navigation and Safety of Sea Transportation

2008

Vol. 2, no. 3

263--268

In paper the functional requirements and the radiocommunication services of Global Maritime Distress and Safety System (GMDSS) in respect of the E- Navigation has been described. Some aspects of the improvement of GMDSS equipment and the utilization of the improved GMDSS as a data communication network for E-Navigation has been presented. The items relating to technical improvement of the GMDSS which should be considered as one of the discussion on the strategy plan of E-Navigation was given.
