Navigation is a term with broad usage in everyday life and can mean the act of moving, moving through an unknown environment, ascertaining a craft's position, or even browsing on the Internet. Originally, the term meant the skill of sailing a ship, in particular steering and maneuvering, and is derived from the Latin words navis and agere, meaning "ship" and "to drive." The modern field of study of navigation in a scientific context usually relates to the ascertainment or determination of position, velocity, and orientation of some object relative to a reference point and is used for all type of crafts and vehicles, such as aircraft, ships, submarines, and cars.
