[mə′rēn ‚nav·ə′gā·shən] (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.
Marine navigation is planning managing and directing a vessel’s voyage. The practice of marine navigation involves: good seamanship. professional knowledge and judgement. the application of science and technology.
Definition of navigation
1 : the act or practice of navigating. 2 : the science of getting ships aircraft or spacecraft from place to place especially : the method of determining position course and distance traveled. 3 : ship traffic or commerce.
Navigation derived from the Latin words “navis” (meaning “ship”) and “agere” (meaning “to drive”) is the process of accurately determining the position and controlling the movement of a craft or vehicle along a desired course.
The purpose of navigation is to ascertain the present position and to determine the speed direction etc. to arrive at the port or point of destination.
A navigation system is an instrument that determines the position of a vehicle and the route to a particular place. … The navigation system uses GPS signals to determine the vehicle’s current location and direction.
Each button corresponds to the direction that you can move in a menu. … For example to move right in a menu press the navigation button that is located on the right side. If you want to move down in a menu press the navigation button that is located on the bottom.
It is important in marine navigation for the ship’s officer to know the vessel’s position while in open sea and also in congested harbors and waterways. … Vessel traffic and other waterway hazards make maneuvering more difficult and the risk of accidents becomes greater.

The twentieth century brought important advances to marine navigation with radio beacons radar the gyroscopic compass and the global positioning system (GPS). Most oceangoing vessels keep a sextant onboard only in the case of an emergency.
The magnetic compass work in conjunction with the magnetic field of the earth and is the essential means of the direction indicating device. It is used to get a planned course for the voyage. This ship navigation equipment is usually fitted at the centre line of the ship on the monkey island.
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.
GPS is a system of 30+ navigation satellites circling Earth. We know where they are because they constantly send out signals. A GPS receiver in your phone listens for these signals. Once the receiver calculates its distance from four or more GPS satellites it can figure out where you are.
How do a GPS work?
How GPS works. GPS satellites circle the Earth twice a day in a precise orbit. Each satellite transmits a unique signal and orbital parameters that allow GPS devices to decode and compute the precise location of the satellite. GPS receivers use this information and trilateration to calculate a user’s exact location.
NAVIGATION SATELLITES. Artificial satellites can provide the basis for all-weather long-term navigation systems to determine with accuracy geodetic position speed and direction of a surface vehicle or aircraft north reference and vertical reference.
The methods used in this chapter include pilotage—navigating by reference to visible landmarks dead reckoning—computations of direction and distance from a known position and radio navigation—by use of radio aids.

A navigation system is a computing system that aids in navigation. … Navigation systems may be capable of one or more of: containing maps which may be displayed in human-readable format via text or in a graphical format. determining a vehicle or vessel’s location via sensors maps or information from external sources.
