e-Navigation and Future Trend in Navigation

The International Maritime Organization (IMO) adopted the following definition of e-Navigation: “e-Navigation is the harmonised collection, integration, exchange, presentation and analysis of maritime information onboard and ashore by electronic means to enhance berth to berth navigation and relat-ed services, for safety and security at sea and protection of the marine environment”. A pre-requisite for the e-Navigation is a robust electronic positioning system, possibly with redundancy. A new radar technology emerged from the last IALA-AISM conference held in Cape Town, March 2010, where almost all the manu-factures companies involved on navigation surveillance market presented –at various state of development- solid state products for VTS and Aids to Navigation indicating a new trend for this application. The paper present an overview of the systems for global navigation and new trend for navigation aids. The expected de-velopments in this field will also be briefly presented.
