Methods of electronic navigation include: Satellite navigation, satellite navigation systems. Radio navigation, the application of radio frequencies to determining a position.
What is the advantage of e-navigation?
e-navigation can thereby help reduce navigational accidents, errors and failures by developing standards for an accurate and cost-effective system that would make a major contribution to the IMO’s agenda of safe, secure and efficient shipping on clean oceans.
What are the 4 stages of passage planning?
There are four stages for passage planning:
- Appraising all relevant information.
- Planning the intended voyage.
- Executing the plan taking account of prevailing conditions.

- you have to pay port duties and taxes.
What are the disadvantages of electronic navigational chart?
Currently, the main disadvantage of the electronic chart is screen size, although large displays of more than 40 inches are becoming affordable. The minimum size of display for an approved ECDIS is 21 inches, which provides about a sixth of the coverage area of the traditional paper chart.
How often should operational checks on navigation equipment be done?
The OOW should undertake daily tests and checks on the bridge equipment, including the following: Manual steering should be tested at least once a watch when the automatic pilot is in use. Gyro and magnetic compass errors should be checked once a watch is possible and after any significant course alteration.
