1. E-Navigation Integrated System Architecture Colin Brown safer lives, safer ships, cleaner seas

2. The Aim • “The aim is to develop a strategic vision for e-navigation, to integrate existing and new navigational tools, in particular electronic tools, in an all-embracing system that will contribute to enhanced navigational safety (with all the positive repercussions this will have on maritime safety overall and environmental protection) while simultaneously reducing the burden on the navigator” (IALA) safer lives, safer ships, cleaner seas

3. The Present Situation ? What is the status of the current and legacy aids available to navigators such as : • Position fixing systems ? • Collision and grounding avoidance systems ? • Charts & publications ? • Bridge displays and operation ? • VTS and other shore displays and operation ? • Communications ship/ship, ship/shore, shore/shore ? • Security ( commercial and safety related) ? • Training, certification and competence in general ? • etc., etc.. safer lives, safer ships, cleaner seas

4. An Optimum Future Situation ? • What are the desired E-Navigation capabilities ? • What are the gaps between what we have and what we want ? • What needs to be done to bridge those gaps ? • Is the technology available to do so ? • Is the technology scaleable for smaller vessels ? • Will the new system allow a phased migration to E-Navigation ? • Will it be capable of low cost generational change as new capabilities and functionality are developed ? safer lives, safer ships, cleaner seas

6. A Proposed System Architecture? • What kind of system architecture should UKSON propose? • How could its design be approached ? • What should we include in the design? • What has been done so far ? safer lives, safer ships, cleaner seas

7. Some System Architecture Definitions • A system architecture or systems architecture is the design or set of relations between the parts of a system. There is no strict definition of which aspects constitutes a system architecture, and various organizations define it in different ways, including: • A representation of a system in which there is a mapping of functionality onto hardwareand software components, a mapping of the software architecture onto the hardware architecture , and human interactionwith these components. • The structure of components, their interrelationships, and the principles and guidelines governing their designandevolution over time safer lives, safer ships, cleaner seas

8. This type of system architecture simply shows the data types within, and contributors to, the system : safer lives, safer ships, cleaner seas

10. Whereas this one just illustrates the major components : safer lives, safer ships, cleaner seas

11. Example - AMVER (Courtesy of US Coastguard) safer lives, safer ships, cleaner seas

12. So what do we need for an E-Navigation systems architecture representation which satisfies the definitions, is adequate for international recognition - and is of practical use ? safer lives, safer ships, cleaner seas

13. An E-Navigation System Architecture • It will be a representation because it will be used to convey the informational content of the elements comprising the system, the relationships among those elements, and the rules governing those relationships. • It will be a process because a sequence of steps will be prescribed to produce - or change - the architecture, and/or a design from that architecture, of the system within a set of constraints . • It will also be a discipline because the body of will be used to inform practitioners as to the most effective way to design the system within that set of constraints. safer lives, safer ships, cleaner seas

16. An Australian View • The following diagram is the output of the national workshop called on November 22nd by the Australian Maritime Safety Agency which, in many respects, could be called “a mariners’ view”, • Its major output is a descriptive model of the E-Navigation concept. • It lists inputs and outputs to and from an E-Navigation Core, but without detailing the system in which they are processed. • The model should be viewed in conjunction with the Correspondence Group diagram in the next-but-two slide. safer lives, safer ships, cleaner seas

18. CG Amalgamated Diagram • The following draft diagram, together with the Australian descriptive model shown previously, are the results of the international Correspondence Group work, co-ordinated in the UK by the Galileo Programme Division / Ports Division of the Department for Transport. • Modification and expansion of this and the AMSA diagrams are probably necessary. safer lives, safer ships, cleaner seas

20. Further work • UKSON members and all invitees to this workshop are requested to comment on the gap analysis and system architecture results presented to date and to suggest additions, improvements or other changes to it. • It is appreciated that such diagrams are simply graphical representations of a complex system, and that much supporting data is required. • Such data will include process flow analysis charts, breaking sections of the system down into component elements. safer lives, safer ships, cleaner seas
