What are the basics of navigation?
Basic Navigation
- Longitude and Latitude. To be able to describe your position anywhere in the world, you can use Latitude and Longitude.
- Speed & Distance. 1 Nautical Mile = 1852 metres.
- Time. When working out time, it is best to use the 24 hour clock.
- Steering a Course.
- Variation.
- Deviation.
- Relative Bearings.
- Transit Bearing.
What is terrestrial and coastal navigation 2?
Terrestrial and Coastal Navigation 2 enables a prospective marine deck officer to plan and conduct a passage and determine the ship’s position. The course includes topics on sailings, position lines and positions.
How many main navigation types are there?
Structural navigation can be further subdivided into two types: main navigation and local navigation.
How do chartplotters work?
How does a chartplotter work? A chartplotter combines the GPS data with electronic charts. Generally you simply download these charts, or maps (payed or for free) from your computer onto the device. The maps are simply an interface to make it more easy for us humans to use GPS.
What is terrestrial navigation?
Terrestrial Navigation-is the method of navigation in which the position is determined through terrestrial objects/landmarks such as headlands, buoys, lighthouses, or any objects on the surface of the earth.
What is the use of navigation?
Navigation is the art and science of determining the position of a ship, plane or other vehicle, and guiding it to a specific destination. Navigation requires a person to know the vehicle’s relative location, or position compared to other known locations. Navigators measure distance on the globe in degrees.
What are the uses of navigation system?
Location – determining a position. Navigation – getting from one location to another. Tracking – monitoring object or personal movement. Mapping – creating maps of the world.
What is navigation key?

Where does DED come from?
Where does ded come from? Ded is a misspelling—intentional or otherwise—of dead. An early use of ded comes from a folk etymology for the old navigation term dead reckoning, a way of calculating your location, especially at sea, by estimating the distance and direction you’ve traveled.
What is Dr position in ship?
dead reckoning, determination without the aid of celestial navigation of the position of a ship or aircraft from the record of the courses sailed or flown, the distance made (which can be estimated from velocity), the known starting point, and the known or estimated drift.
What is dLat and dLong?
The sides of the top triangle are Distance, difference in latitude (dLat) and Departure. Departure is the longitude distance in miles. The lower triangle relates Departure to the difference in longitude (dLong.)
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.
