What is ECDIS and how does it work?
The ECDIS utilises the feature of the Global Positioning System (GPS) to successfully pinpoint the navigational points. It also has to be noted that the ECDIS adheres to the stipulations set by the International Maritime Organisation, and thus it adds to the trustworthiness of the electronic chart system.
What types of charts does an ECDIS use?
An electronic navigation chart, also known as a vector chart, is the primary type of chart that an ECDIS uses. This is a fully modern, digital chart that incorporates all of the advantages of electronic navigation. Computer generation comes with a wealth of data and additional features, such as depth alerts and customizable visuals.
How does ECDIS comply with the SOLAS Convention?
ECDIS complies with IMO Regulation V/19 & V/27 of SOLAS convention as amended, by displaying selected information from a System Electronic Navigational Chart (SENC). ECDIS equipment complying with SOLAS requirements can be used as an alternative to paper charts.
Are all ships fitted with ECDIS?
Not all ships are fitted with ECDIS and hence one cannot be sure of technical ability with regard to positioning as well as navigation; the kind that ECDIS provides It is never prudent for the OOW to depend solely on the information on the ECDIS.
What are the main functions of ECDIS?
ECDIS has some functions which indicate not only chart's information but also other information and has functions that give to ship's navigator an alarm when a ship is approaching or entering into potentially dangerous areas. superimposing with Radar and other images, etc.
What is the difference between ECDIS and Radar?
ECDIS makes possible an automatic and continuous monitoring of the ship's position in relation to the planned track and the hydrographic situation. Radar/ARPA is an indispensable tool for navigation, detection, acquisition, tracking, and display of other ships for the purpose of collision avoidance.
What are the 3 mandatory sensors of ECDIS?
The sensors providing the data inputs to ECDIS are the following: The global positioning system (GPS and/or DGPS). The automatic identification system (AIS). The radar and automatic radar plotting aid (ARPA).
What are the 5 ECDIS mandatory alarms?
The five mandatory alarms (as per IMO ECDIS Performance standards) are: crossing safety contour, deviation from route, positioning system failure, approach to critical point and different geodetic datum.
How many types of ECDIS are there?
two typesThere are two types of electronic charts that an ECDIS can display: Raster Navigational Charts (RNCs) and Electronic Navigational Charts (ENCs,) otherwise known as vector charts.
What are the errors of ECDIS?
Source Error : An electronic chart can be as good as the original data it was derived from. Position shift : There will be position shift shown between GPS and actual position on the chart if the GPS and the chart are using different datum's.
What are the major parts of ECDIS?
ECDIS familiarisation should follow a structured plan and cover the following areas:familiarisation with available functions.familiarisation with the menu structure.display setup.setting of safety values.recognition of alarms and malfunction indicators and action to be taken.route planning.route monitoring.More items...•
What is ECS in navigation?
Electronic Chart System (ECS) is a new type of vessel navigation system and aid in decision making system. It can not only continuously give out the position of the vessel but also provide various types of information relating to navigation to effectively prevent all kinds of hazards.
What is ECDIS capable of?
ECDIS should be capable of displaying all chart information necessary for safe and efficient navigation originated by and distributed on the authority of government authorized hydrographic offices
What is ECDIS in navigation?
What is Electronic Chart Display and Information System (ECDIS)? The Electronic Chart Display and Information System (ECDIS) is a development in the navigational chart system used in naval vessels and ships.
What is ECDIS in real time?
All information is processed and displayed in real time. It eases the process of passage planning. One can get all necessary navigational information at a glance. Alarms and indications are in place to indicate and highlight dangers. Chart correction is made easier in ECDIS as compared to paper charts.
How long is the ECDIS course?
ECDIS Training. There are many institutes that conduct the ECDIS course. It is usually a 5 days extensive course for which candidates must have completed a year at sea as a Deck Cadet. Every institution has a different price range for the course and that must be checked on the institute’s website itself.
What is the IMO resolution for ECDIS?
In addition to the general requirements for shipborne radio equipment forming part of the GMDSS and for electronics navigational aids contained in IMO Resolution A.694 (17), ECDIS should meet the requirements of this performance standard
Do all ships have ECDIS?
Not all ships are fitted with ECDIS and hence one cannot be sure of technical ability with regard to positioning as well as navigation; the kind that ECDIS provides
Should ECDIS be avoided?
Over-reliance on ECDIS for navigational safety should be avoided until it is confirmed that all the data transmitted, received and displayed are accurate

What is an ECDIS?
However, an ECDIS isn't simply a digitized replacement for traditional charts.
What is the function of ECDIS?
The exact function of an ECDIS depends on the type of charts that a ship is currently using. When a ship deploys the latest electronic navigation charts, it enjoys the full breadth of information, automation and safety features. Sometimes, though, it's necessary to use Raster Charts, which are light on features.
How does ECDIS work?
The ECDIS works by incorporating robust, specialized electronic navigation software with many modern navigational tools. This includes fixtures such as GPS, RADAR, ARPA and numerous others. You can use your ECDIS to access information from these sources, check Tide Tables and check virtually all relevant navigational information.

What is ENC in a ship?
By using ENC's, the ECDIS is able to ascertain precise depth information and early-warning on any potential hazards along the route. A crew can gain even more precise information by calculating and inputting figures such as squat, which can pull a ship closer to the seabed. This information feeds into several other automated functions, providing for extremely accurate route safety judgments and automated safety warnings.
Is ECDIS a digitized chart?
However, an ECDIS isn't simply a digitized replacement for traditional charts. ECDIS charts typically incorporate much more information than past navigation tools, and automate many essential functions. For instance, the navigator now has a much lighter burden thanks to automatic route planning and monitoring.
