The IMO's e-Navigation concept is defined as "the harmonised collection, integration, exchange, presentation and analysis of maritime information onboard and ashore by electronic means to enhance berth to berth navigation and related services, for safety and security at sea and protection of the marine environment".
Structural components (many already exist on some vessels):
- Integrated displays using Electronic Chart Display Information Systems (ECDIS)
- Electronic Navigation Charts (ENCs)
- Electronic Positioning Fixing Systems (EPFS)
- Vessel route and status information
- Transmission of positional and navigational information using AIS
- Information prioritisation and alarm management
