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 include:

  • Integrated displays using Electronic Chart Display Information Systems (ECDIS)
  • Electronic Positioning Fixing Systems (EPFS)
  • Information prioritisation and alarm management
  • Maritime Service Portfolios (MSPs)
  • The Common Maritime Data Structure (CMDS) based on IHO S-100
  • The Maritime Cloud

e-Navigation encompasses a Service Oriented Architecture (SOA) based maritime, geolocated, Information Technology system; the communications backbone for which is known as the Maritime Cloud.

The Maritime Cloud consists of:

  • The Maritime Identity Registry (MIR)
  • The Maritime Service Registry (MSR)
  • The Maritime Messaging Service (MMS)


The MC allows the seamless interchange of data from service provider to service consumer via disparate physical communication technologies; satellite, VDES, LTE, etc.

As e-Navigation develops, the GLAs via R&RNAV are:

  • Supporting the UK Government and the IMO in e-Navigation development and standardisation
  • Participating in the work of IALA in developing requirements and standards for the shore-side infrastructure to support e-Navigation
  • Investigating the format and content of AtoN information the GLAs may need to provide to optimise the operation of e-Navigation
  • Investigating applications of e-Navigation that will provide benefits for the GLAs and their stakeholders
