If the system needs to send a distress signal or a call
for help, this is done as follows. By pressing the
emergency button as shown in Figure 8, the signal is
sent to a special server via the nearest mobile phone
mast via a gateway, the information is then processed
by the operator, who directly initiates the rescue
measures, i.e. it is guaranteed that the signal is received
immediately.

The company can forward the information packet
from the gateway to the nearest Rescue Centre or VTS.
If the mobile signal is weak or absent, the information
can also be transmitted directly to the Thuraya satellite
or to another satellite system.
5 CONCLUSIONS
The use of Iridium and Thuraya satellite systems on
inland waterway vessels ensures the safety of
communication and navigation thanks to their global
coverage and the quality and reliability of their
communication.
In remote and inaccessible shipping areas where
traditional radio communication methods could fail,
satellite technologies enable integration with terrestrial
analogue-digital radio systems.
The solution proposed in this paper for the
integration of DSC devices with the Iridium system
enables precise and accurate tracking of the vessel,
immediate transmission of navigational information
and instant response and interaction with SAR centres
in emergencies where the lives of crew members are in
danger.
The integration of the DSC VHF subsystem for
shipping with the Iridium satellite system enables the
transmission of navigation information for the needs of
inland waterway vessels.
The algorithms used in the integration and
processing of navigation and operational data enable
comprehensive cooperation between ships in maritime
and inland traffic.
