Terrestrial maritime radio communication system
using digital selective calling (DSC) during the
practical operation as the core part of the GMDSS
revealed obvious imperfections for the user - the
officer of the watch (OOW) of a marine vessel.
Evident shortcomings of DSC were noted from the
first years of the GMDSS operation to the present [7, 8,
11]. The complexity of DSC operational procedures,
the choice of frequencies and the variety of transceiver
control panels evidently do not contribute to the
correct implementation of radio communication
procedures by the OOW, and often leads to neglecting
the DSC at all. Attempts to correct the situation within
the framework of improving only the DSC equipment
(enlarged screen, soft keys, scroll handles) did not
give much result.
The idea of radically improvements DSC interface
on the base of integration communication and
navigation equipment was suggested first in [8]. This
suggestion is fully compatible with the E-navigation
strategic direction which (that) envisages further
development of means of radiocommunication and
navigation on the base of their integration (on the
platform of Integrated Navigation System (INS)) and
the implementation of modern digital information
technologies in navigation.
In fact in document “First draft of revision of
resolution A.806 (19)” [11] the improvements of
MF/HF DSC were suggested to be provided in the
frame of E-navigation concept.

ABSTRACT: 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.
