Systems (ECS)


AIS (automatic identification system)

a system which complies with the requirements of IMO resolution MSC.74(69) Annex 3.*


ARPA (automated radar plotting aid)

a system which complies with the requirements of IMO resolution A.823(19).†


ATA (automated tracking aid)

a system which complies with the requirements of IMO resolution MSC.64(67) Annex 4.‡


base display

see “display base”.


CCRP (consistent common reference point)

a location on own ship, to which all horizontal measurements such as target range, bearing,

relative course, relative speed, CPA or TCPA are referenced, typically the conning position of

the bridge.


clearing line

see danger bearing.


CPA (closest point of approach)

the closest distance a tracked target is expected to pass own ship.


conspicuous features

objects, either natural or artificial, which are distinctly and noticeably visible.


danger bearing

the maximum or minimum bearing of a point for safe passage of an off-lying danger.


display base

the level of information which cannot be removed from the presentation of a vector format

ECS database, consisting of information which is required at all times in all geographic areas

and all circumstances. It is not intended to be sufficient for safe navigation.


display equipment

a device capable of representing information visually.


ECDIS (electronic chart display and information system)

a navigation information system meeting requirements of IMO Resolution A.817(19), as amended

which, with adequate back-up arrangements, can be accepted as complying with the up -to-date

chart required by regulation V/19 of the 1974 SOLAS Convention, as amended, by displaying

selected information from a system electronic navigational chart (SENC) with positional

information from navigation sensors to assist the mariner in route planning and route monitoring,

and by displaying additional navigation-related information if required.. *


ECS (electronic chart system)

navigation information system that electronically displays vessel position and relevant nautical

chart data and information from the ECS database on a display screen, but does not meet all

the IMO requirements for ECDIS.


ECS database

the database used by an ECS.


ECS database presentation

see operational display area.


ENC (electronic navigational chart)

the database, standardized as to content, structure and format, issued on the authority of

government authorized hydrographic offices. The ENC contains all the chart information

necessary for safe navigation and may contain supplementary information in addition to that

contained in the paper chart (e.g. sailing directions) which may be considered necessary for

safe navigation. The ENC product specification is contained in Appendix B to IHO Special

Publication No S-57


EPFS (electronic position fixing system)

a receiver for GNSS or a terrestrial radionavigation system, or other means, suitable for use

at all times throughout the intended voyage to establish and update the ship’s position by

automatic means.



the directi on in which the bow of a ship is pointing expressed as an angular displacement

from north.


important indication

a marking of operational status of displayed information which needs special attention, e.g.,

information with low integrity or invalid information.



measured, acquired, computed or manually entered data that is presented according to

international conventions, appropriately complemented with type, source and properties so

that it can be understood, within the context of its presen tation, by properly trained mariners.


inland ENC (inland electronic navigational chart)

the database, standardised as to content, structure and format , issued for inland navigation.

The Inland ENC complies with the IHO standard S-57, enhanced by the additions and

clarifications of the Inland ECDIS Standard . The Inland ENC contains all essential chart

information and may also contain supplementary information that may be considered as

helpful for navigation.



the property of information as being accurate, valid and uncorrupted with regard to specified

requirements and verified by comparing data from more than one independent source.



time interval between an event and its result, including time for reception, processing,

transmission and display.



an area of the display that is allocated to the interactive display and operation of a structured

menu for the selection and entry of operational parameters, data and commands. The menu

display, when selected, is typically replacing parts of or the whole data display.


MKD (minimum keyboard display)

a minimum display and input device for AIS that provides the following:

Display of at least (3) lines of data. Each line to display at least bearing, range, and name

of ship. Horizontal scrolling of bearing and range is not allowed. The title of the display

shall be visible.

Manual input of voyage and safety related messages, control of AIS and data selection.

The MKD is an essential part of the AIS and it may be remote.


nautical chart or nautical publication

a special -purpose map or book, or a specially compiled database from which such a map or

book is derived, that is issued officially by or on the authority of a Government, authorized

Hydrographic Office or other relevant government institution and is designed to meet the

requirements of marine navigation.


NTM (notice to mariners)

a periodic publication used to correct charts and publications.
