What is Electronic Navigation Systems?

Electronic navigation are forms of navigation that ships, land vehicles, and people can use, which rely on technology powered by electricity. Methods of electronic navigation include: Satellite navigation, satellite navigation systems. Radio navigation, the application of radio frequencies to determining a position.


The main aim of e-Navigation is to enhance navigation safety of the ships while simultaneously reducing the burden on navigational officers. A well coordinated and systematic system under e-navigation would considerable increase the efficiency of the ships not only at the sea but also at the ports.

Frequently Asked Questions

What are the 3 types of navigation?

As with different ways to describe location, there are also different ways to navigate places. Three main types of navigation are celestial, GPS, and map and compass.

What is the difference between ECS and ECDIS?

A genuine ECDIS is a high quality ECS that meets the requirement of the IMO performance standard and has been tested by an independent type -approval authority. Only type-approved ECS can legitimately be called ECDIS and only they are considered by the regulatory authorities to meet the requirements of SOLAS.

Which device is used for navigation?

A satellite navigation device, colloquially called a GNSS receiver, GPS receiver, or simply a GPS, is a device that is capable of receiving information from GNSS satellites and then calculate the device’s geographical position.

How is radar used in navigation?

A mandatory aid to navigation, the radar is used in identifying, tracking (with integrated ARPA) and positioning of vessels (including one’s own vessel) among other things in order to adhere to the COLREGs so as to safely navigate a ship from one point to another.

Why is electronic navigation important for oceanographers?

Because the ship’s GPS position is embedded in these transmissions, all essential information about vessel movements and contents can be uploaded automatically to electronic charts. The safety and security of vessels using this system is significantly enhanced.

What do you understand about Ecdis?

The Electronic Chart Display and Information System (ECDIS) is a sophisticated route charting, planning, and navigational system that allows members of the Marines Corps to accurately map out their voyages and minimize risk along the way.

What are the 4 types of navigation?

The field of navigation includes four general categories: land navigation, marine navigation, aeronautic navigation, and space navigation.

What was used before GPS or digital navigation?

To do this, Columbus used celestial navigation, which is basically using the moon, sun, and stars to determine your position. Other tools that were used by Columbus for navigational purposes were the compass, hourglass, astrolabe, and quadrant.

What are the three main tools of navigation tools?

Maps, compasses, astrolabes, and calipers are among the early tools used by ocean navigators. In the modern era, these tools have been largely replaced by electronic and technological equivalents. Despite these early beginnings, it would take many centuries before global navigation at sea became possible.

How is GPS used in navigation?

The Global Positioning System (GPS) is a navigation system using satellites, a receiver and algorithms to synchronize location, velocity and time data for air, sea and land travel.

What is safety of navigation?

Safety systems for general navigation are the basic tools used by mariners to fix vessel position, obtain information about the physical environment and operating conditions, and communicate with other vessels and shore-based personnel.

What is navigation in maritime?

(navigation) The process of directing the movements of watercraft from one point to another; the process, always present in some form when a vessel is under way and not drifting, varies with the type of craft, its mission, and its area of operation.

What system is used for marine communications?

VHF radio made ship-to-ship communication a reality, and shortly thereafter Digital Selective Calling (DSC) allowed for greater communication capabilities including remote control commands that could transmit and receive distress signals, place urgent safety calls, and put out routine messages.

What is the name of process of navigation?

Answer. Answer: Web navigation refers to the process of navigating a network of information resources in the World Wide Web, which is organized as hypertext or hypermedia. The user interface that is used to do so is called a web browser.

Is navigation the same as GPS?

S.NO. GPS is a fully-functional satellite-based navigation system. Satellite navigation is a system based on a wide network of artificial satellites. GPS satellites transmit continuous microwave radio signals composed of two carriers, two codes and a navigation message.
