A navigator is the person on board a ship or aircraft responsible for its navigation.<ref name="">Grierson, Mike. Aviation History—Demise of the Flight Navigator, website, October 14, 2008. Retrieved August 31, 2014.</ref> The navigator's primary responsibility is to be aware of ship or aircraft position at all times. Responsibilities include planning the journey, advising the ship's captain or aircraft commander of estimated timing to destinations while en route, and ensuring hazards are avoided. The navigator is in charge of maintaining the aircraft or ship's nautical charts, nautical publications, and navigational equipment, and generally has responsibility for meteorological equipment and communications.

With the advent of GPS, the effort required to accurately determine one's position has decreased by orders of magnitude, so the entire field has experienced a revolutionary transition since the 1990s with traditional navigation tasks being phased out. The U.S. Air Force and U.S. Navy, for instance, no longer teach aviators how to do celestial navigation.
