Some aspects of the modernization plan for the GMDSS

Korcz K.

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

2017

Vol. 11, no. 1

167--174

Preliminary Modernization Plan for the Global Maritime Distress and Safety System (GMDSS) have been presented. On the base of a current status of the GMDSS and the discussion on a modernization topic some aspects of the Modernization Plan for the GMDSS, both regulatory and technical nature, have been described. Future work on the Modernization Plan for the GMDSS have been discussed as well.

Maritime Communications in RIS System for Inland Navigation

Lisaj A.

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

2015

Vol. 9, no. 2

287--291

The article presents the VHF communications system architecture for inland navigation within the area of operation of the RIS-PL Centre. The author has described the communication system modules used in the RIS on the Lower Oder stretch and presented the relevant equipment specification. The present condition of the system has been described, taking into consideration the location of its components, both in the field and in the environment, of key importance for VHF communication. The feasibility of implementation of GMDSS subsystems for integrated navigational data transmission in maritime and inland navigation at the RIS-PL Centre has been discussed.

Satellite-based AIS and its Comparison with LRIT

Cheng Y.

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

2014

Vol. 8, no. 2

183--187

The satellite-based Automatic Identification System (AIS) system has continuously been developed by the shipping industry in recent years. This paper introduces the satellite-based AIS including the concept, the system structure, the development and its new applications. The Long Range Identification and Tracking (LRIT) system, which is mandatory to be required on certain classes of ships engaged on international voyages to report their position at least every six hours using onboard communication means however, has similar kind of function of ship monitoring with the satellite-based AIS system. Based on the basic introduction of the LRIT system, this paper presents the comprehensive comparison between satellite-based AIS and LRIT in terms of the ship’s cost, the communication scheme, the monitoring coverage, the information details and the information creditability. The conclusion that the satellite-based AIS should be encouraged to effectively play a complement role to the LRIT system is advanced in the paper.

Some Radiocommunication Aspects of e-Navigation

Korcz K.

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

2009

Vol. 3, no. 1

93--97

In the paper some radiocommunication issues concerning Global Maritime Distress and Safety System (GMDSS) in respect of the e - Navigation have been described. Some aspects of the existing technical and regulation constraints and limitations referring to GMDSS equipment and systems have been given. The issues relating to the need of GMDSS modernization taking into account new technology and the discussion on the e-Navigation program have been presented.
