ECDIS is an advanced navigational system used by ships. It combines electronic charts with radar, GPS, and other navigational aids to provide a comprehensive view of the ship’s position about its surroundings. ECDIS allows for safer navigation, more efficient route planning, and real-time updates on weather conditions, sea state, and other essential factors that can affect a ship’s voyage. This system has become increasingly popular due to its ability to improve safety at sea and reduce the risk of human error in navigation. The purpose of an ECDIS is to provide more accurate, safe navigation for the ship. This system combines radar, GPS, and other navigational aids for greater accuracy and faster route planning. It also provides real-time updates on weather conditions, sea state, and other essential factors that can affect a voyage at sea. An ECDIS has become increasingly popular due to its ability to reduce the risk of human error in navigation while improving safety at sea.

Electronic Chart Display And Information System (ECDIS)

An improvement in the nautical chart system used by ships and navy vessels is the Electronic Chart Display and Information System (ECDIS). The marine crew of a ship now has an easier time locating specific places and obtaining directions thanks to the usage of computerized charts.


By showing specific information from a System Electronic Navigational Chart, ECDIS conforms with IMO Regulations V/19 and V/27 of the SOLAS convention as modified (SENC). Paper charts can be replaced with ECDIS technology that complies with SOLAS regulations.

Along with increasing navigational safety, automated features like route planning, route monitoring, automatic ETA computation, and ENC updating considerably reduce the effort of the navigator. Other advanced navigation and safety functions offered by ECDIS include continuous data recording for later analysis.

The ECDIS uses the Global Positioning System (GPS) function to identify navigational locations accurately. Additionally, it should be emphasized that the ECDIS complies with the rules established by the International Maritime Organization, which increases the reliability of the electronic chart system.

In its simplest form, ECDIS is a navigational information system that interfaces with various navigational tools like the GPS, Gyro, RADAR, ARPA, Echo Sounder, and others.

Additionally, ECDIS includes and displays data from other nautical publications like tide tables and sailing directions and data from other sources, including radar, weather, ice conditions, and automatic vessel identification.

What Are The Uses Of ECDIS In Ship?


ECDIS is a computer-based navigation system used on ships to provide navigational information. It is used to display electronic charts and other navigational data and provide route planning, monitoring, and tracking capabilities. ECDIS is an essential tool for the safe navigation of ships, allowing the crew to make informed decisions about their voyage. Using ECDIS helps reduce the risk of human error in navigation and increases safety at sea. It also allows for faster passage planning, improved situational awareness, and better decision-making when navigating difficult conditions. ECDIS can also be used to monitor vessel performance, such as speed over ground or fuel consumption, helping ship operators save time and money. ECDIS is now mandatory on larger vessels in most countries. Although the development and use of electronic navigation were not new, the introduction of ECDIS technology marked a significant change in modern navigation. Electronic navigational systems have been used since the late 1970s, but they were designed primarily to support military operations. Early electronic charts needed more features and required manual updating by the navigator, making them less useful than paper charts. The addition of graphical displays and digital presentation increased awareness of what could be done with computers in chart display, opening up possibilities for how freely data could be shown on screens and changes.

How To Use ECDIS In Ship?

ECDIS is a technology used in the maritime industry to help ships navigate safely. ECDIS provides a digital platform for navigation and replaces traditional paper charts. It also allows ships to identify obstacles in their path and avoid them. The system combines data from various sources, such as weather, maritime notes, and route planning, into one digital platform on a tablet or computer.


ECDIS is used by mariners to plan, monitor, and execute safe voyages on the sea. It helps them to track their ship’s position, speed, heading, course over ground, distance traveled, and other important information related to their voyage. In addition, ECDIS can also be used for route planning by providing detailed information about the terrain of the sea floor and any potential hazards that may lie ahead. With its user-friendly interface, ECDIS makes it easier for mariners to understand the navigation data they are presented with. A navigation chart is a detailed map showing an area’s coastline or waters. They are drawn to scale, are accurate, and can be used for several purposes in navigation. , including calculations of distances, speed, and direction. They can also be used in chart plotting to give the position of any point on the chart. A navigation chart is sometimes called a maritime chart or nautical atlas. Nautical charts are available on ECDIS displays and have been made more accurate with improved cartography in recent years, thanks to modern GPS receivers and computer mapping programs. In addition, they are now being made interactive so that they can be downloaded onto one’s tablet or smartphone for use when away from shore. The precision of these new interactive charts is limited

Troubleshooting the Electronic Chart Display and Information System (ECDIS) on a ship can be daunting, especially when you are in unfamiliar waters. The ECDIS is a complex system that requires knowledge of navigation and charting systems to operate correctly—troubleshooting the ECDIS on a ship and tips for avoiding potential problems. We will also discuss everyday use cases for troubleshooting the ECDIS, including data entry errors, software issues, hardware malfunctions, and more. ECDIS is functioning correctly so that your voyage is safe and successful. The ECDIS is a complex system and requires knowledge of navigation and charting systems to operate correctly. Common Use Cases of Troubleshooting the ECDIS: Data entry errors: If you receive a data entry error while working on the ECDIS, your data will likely be saved incorrectly. Keep your data and clear the system cache using a command keystroke as a first step in troubleshooting this issue. Software issues: Many software-related problems can be resolved by simply restoring or re-installing the software of your choice. Hardware malfunctions: If you are experiencing any issues with the hardware components of your ECDIS, such as malfunctioning displays or buttons, it might be time for an upgrade!


Ambiguous Presentation Of Sector Lights

Sector lights are beacons that direct ships to avoid rugged terrain, such as underwater obstructions, using several hue light beams. Lights are on a separate layer and turned off by default in the ECDIS sector. The ECDIS sector light icons do not relate to the specific hazard they indicate, in contrast to the paper chart equivalents. To be sure of their meaning, the officer must study pilot documentation. The officer did see the sector light in the Nova Cura collision, but he mistook it for another shallow spot on the road. The safety board concluded that interpretation mistakes are possible because the ENC chart’s sector light indicator is not apparent.
