   Navigation systems including developments in e-navigation


Development of an e-Navigation strategy implementation plan

The Maritime Safety Committee at its 85. session approved the Strategy for the development and implementation of e-navigation, agreed at NAV 54. The Maritime Safety Committee then at its 86. session approved a proposal for a coordinated approach to the implementation of the e-navigation strategy. The proposal outlines a joint plan of work for the NAV, COMSAR and STW Sub-Committees for the period 2009-2012. The plan requires NAV 55 to finalize the user needs, while NAV 56 should finalize an initial system architecture, complete an initial gap analysis, initial cost benefit and risk analysis. This implies that NAV 56 should consider the recommendations of COMSAR 14 concerning the various components of the system architecture, consider the final report of the Correspondence Group, (- established by NAV 55), and finalize the user needs and the initial system architecture.

From an e-navigation perspective, the relevant devices within the ship environment are the transceiver station, the sensors and applications connected to the transceiver station, the Integrated Navigation System (INS) and the Integrated Bridge System (IBS). The GMDSS function has been included in the ship environment, with a direct link to the transceiver station and a link to the World Wide Radio Navigation System (WWRNS).

The transceiver station is shown as a single station, although in reality there may be several transceiver stations. It interfaces via links with the appropriate technical e-navigation services ashore.

As regards shore-based services there are technical services responsible for interfacing with the ship services. 

Operators ashore, such as VTS, port, pilot station and SAR operators, or lock operators, perform their tasks in co-operation with shipboard applications.  From the shore perspective, it is the functional links between the shore-based user applications and the shipboard applications that are most relevant, such as the provision of MSI.  A similar setup of interactions applies for ship-to-ship and shore-to-shore applications, and would include, for example, real-time and near real-time meteorological and oceanographic services.

Pilots also perform the same interactions as mariners before and when they are on board ships in pilotage waters. The above functional links are equally important to ensure efficient ship to ship, shore to ship and ship to shore communications.

IALA is currently developing a proposed Universal Maritime Data Model (UMDM) for e-navigation to meet requirements arising from the future implementation of e-navigation. It is therefore important to harmonize efforts in data modelling, with the aim of creating and maintaining a robust and extendable maritime data structure.
