Navigation systems including developments in e-navigation  

Navigation systems

D Morgan ILS

This study provides descriptions of major onboard subsystems which form part of current bridge and navigation systems.

These subsystems include:

 Radar and Automatic Radar Plotting Aids (ARPA)
•  Electronic Chart Display and Information Systems (ECDIS)
•  Compass technologies
•  Global Satellite Navigation Systems (GNSS)
•  Long Range Aid to Navigation (LORAN) and eLORAN
•  Automatic Identification System (AIS)
•  Global Maritime Distress and Safety System (GMDSS)
•  Voyage Planning and Weather Routing
•  Voyage Data Recorders (VDR)
•  Integrated Bridge Systems/Integrated Navigation Systems (IBS/INS)
•  Vessel Traffic Services (VTS)
•  Long Range Identification and Tracking Systems (LRIT)
•  Portable Pilot Systems

The study concludes that the present state-of-the-art subsystems listed above will be the building blocks for e-navigation systems of the future and addresses how they can be integrated to contribute to the efficient collection, exchange, presentation and analysis of maritime information to enhance berth to berth navigation and related services.
It is suggested that the rapid pace of technology and the increased functionality which will be provided on the e-navigation bridge of the future bring with them a need to examine and update the regulations and standards which apply to on-board navigation systems. There is a need for continuing dialogue between the relevant regulatory authorities and stakeholders.
This study has concentrated on the on-board equipment and technologies relevant to e-navigation. Many of these are on-board subsystems of larger navigation related systems (e.g. GNSS, GMDSS, AIS/ LRITS networks). The design of future onboard e-navigation systems must therefore be considered as an integral part of the overall e-navigation concept.
