1 INTRODUCTION
The e-Navigation technologies, which integrate the
operation of sea and inland waterway navigation
systems, are applied in the River Information Services
(RIS) system in the process of communications data
management. [9]
Improvement of the safety of navigation and
reduction of the number of errors, including human
errors, e.g., committed by the officer of the watch, is
the most important criterion of collaboration of the
integrated communications platform at a RIS centre
with the VTS systems, rescue coordination centres
(RCCs), and shore-based stations. [11],[12]

SYSTEM USING THE E-NAVIGATION
STRATEGY [9]
2.1 River Information Service (RIS) system [2]
The River Information Service (RIS) system supports
and coordinates the planning of transport on inland
waterways. [1],[3]
Using advanced ICT technologies, a RIS centre
manages traffic in inland waterway transport by
providing operational (e.g., immediate navigation-
related decisions) and strategic (e.g., voyage
planning) services related to the management of
terminals and cargo handling operations. [16]
A RIS centre facilitates reliable verification and
processing of statistical data on inland waterways in

ABSTRACT: The article presents at e-Navigation strategy and implementation plan for RIS centres supporting
inland navigation.
The author describes the RIS centre system architecture and modules collaborating in the process of data
transmission based on e-Navigation technologies.
The functional requirements of e-Navigation strategies for distress communications procedures and ensuring
the safety of inland navigation in compliance with the EU directives are described.
The components of e-Navigation, which integrate state-of-the-art satellite and terrestrial radio communications
systems in the process of effective and efficient management of navigational data transmission, are presented.
The feasibility of implementation of e-Navigation strategies for the Multifunctional Communication System
integrating digital and analog data processing systems in maritime and inland navigation are analysed.
A technological model of the Maritime Navigation Cloud supporting data exchange in the e-Navigation system
is put forward.

the EU Member States. The e-Navigation strategy
makes it possible to harmonise data transmission
standards used by inland navigation authorities for
the purpose of monitoring and strategic planning of
the entire transport chain. [15],[23]
2.2 The e-Navigation strategy architecture for services
provided by RIS centres [6], [23]
The e-Navigation strategy is aimed to integrate
navigational data transmission systems. Increasing
the radio communications capacity, e-Navigation
technologies utilize terrestrial and satellite systems as
well as broadband Internet. [4], [5]
Elements of the e-Navigation strategy (Fig. 1)
integrate state-of-the-art ICT systems available
onboard ships with shore-based stations through RIS
centres. [8]
The module of collaboration between the World-
Wide Radio Navigation System (WWRNS) and the
Common Maritime Data Structure (CMDS) presented
in Fig. 1 ensures uniform operation of the data
management system. [6], [24]
The services performed at a RIS centre are aimed
at coordinating distress alerts. The World-Wide Radio
Navigation System uses the FleetBroadband satellite
broadband terminal equipped with a Distress Call
button in the Voice Distress Services application,
implemented onboard inland waterway craft. [12]
The proposed e-Navigation architecture, which
meets the functional requirements of the RIS system,
features the Marine Service Portfolio module
integrating both sea and inland waterway services.
The MSP is designed to supervise efficient and
effective transmission of navigation data required by
the OOW, with simultaneous correction and
elimination of transmission errors. [6]
3 MODEL OF E-INS INTEGRATED WITH THE RIS
SYSTEM [17]
The e-INS navigation module (Fig. 3), based on e-
navigation technology and integrated into the RIS
system, performs the following functions [13]:
records, verifies and delivers processed data from
external and internal sensors of navigational
instruments, ensuring reliable distribution of
information;
provides a real-time graphical representation of
the navigation process to the OOW;
warns the data operator at the RIS centre of
imminent danger and prepares the system for the
distress procedure;
by means of the Integrated Radio Communication
(IRS) module, enables the captain to communicate
via VHF, MF/HF radio and satellite systems (SAT).
[23]
Using the integrated e-INS navigation system, the
RIS centre applies the UN/EDIFAC (Electronic Data
Interchange for Administration, Commerce and
Transport) standard, uniform across the EU, in the
process of data transmission in electronic ship
reporting. [3], [7]
Application of the e-INS navigation system in the
operation of the RIS centres allows collaboration with
the navigation bridge of inland craft and facilitates:
[14], [17]
finding parameters of the ship’s motion;
imaging the navigational situation on the basis of
ECDIS and Inland ECDIS;
finding the vector of motion of one’s own ship;
position fixing, using the radio navigation and
satellite methods. [8]
