The Revolution and Evolution of e-Navigation Systems—Part 2.

Excerpt from U.S. Coast Guard Proceedings of the Marine Safety & Security Council magazine by Mr. Bill Cairns, F.R.I.N., IALA e-Navigation Committee chairman.

International Association of Marine Aids to Navigation and Lighthouse Authorities

The IALA e-Navigation Committee is structured specifically to support the IMO:

The e-Nav Position, Navigation, and Timing Working Group identifies and examines technologies that may contribute to effective position, navigation, and timing, including radar and associated aids to navigation, terrestrial positioning systems, global navigation satellite systems augmentation, visual and optical techniques, echo sounders, inertial navigation, and alternative uses of existing systems.

The Portrayal Working Group evaluates new proposals for displaying e-Navigation-related information, including AIS application-specific messages, virtual AtoN, and marine information overlays.

The Automatic Identification System Technical Working Group focuses on efforts including AIS aids to navigation, satellite detection, terrestrial long-range AIS, and the next generation of AIS.

The Communications Working Group studies operational and technical requirements for communications and information systems in e-Navigation.

The Architecture Technical Working Group harmonizes sensor and architecture integration. In addition to creating the conceptual and technical framework for a shore-based e-Navigation system, the architects are developing a data model and an “e-Navigation stack” analogous to the International Organization for Standardization open systems interconnection stack.

International Hydrographic Organization
The International Hydrographic Organization is at the heart of the development of electronic navigational charts. IHO has built electronic navigational chart data presentation and transfer standards leading to a template for a new data model known as S-100: IHO Hydrographic Geospatial Standard for Marine Data and Information.

Committee on the Marine Transportation System
The Committee on the Marine Transportation System is a federal inter-departmental committee chaired by the Secretary of Transportation to create a partnership of federal departments and agencies with responsibility for the marine transportation system.

The committee works to develop and implement national marine transportation system policies that are consistent with national needs and reports its views and recommendations to the president.
