The direction of the track relative to magnetic north.



Related Terms

COMPASS TRACK

The direction of the track relative to compass north

GRID TRACK

The direction of the track relative to grid north

NORTH

The primary reference direction relative to the earth; the direction indicated by 000° in any system other than relative. True north is the direction of the north geographical pole; magnetic north the direction north as determined by the earth’s magnetic compass; grid north an arbitrary reference direction used with grid navigation.

FLUX GATE

A detector that gives an electric signal whose magnitude and phase are proportional to the magnitude and direction of the external magnetic field acting along its axis; used to indicate the direction of the terrestrial magnetic field.

RELATIVE BEARING

A bearing relative to the direction of the ship: the clockwise angle between the ship's direction and an object.

MAGNETIC DIP

Angular distance between the horizontal and the direction of a line of force of the earth’s magnetic field at any point. Also called DIP, MAGNETIC INCLINATION.

ELECTROMAGNETIC INDUCTION

The production of electromotive force (EMF) in a conductor through relative motion of a conductor and a magnetic field, or by the change in the strength of magnetic flux around the conductor.

MAGNETIC RANGE

A range oriented in a given magnetic direction and used to assist in the determination of the deviation of a magnetic compass.

VIBRATING NEEDLE

A magnetic needle used in compass adjustment to find the relative intensity of the horizontal components of the earth’s magnetic field and the magnetic field at the compass location. Also called HORIZONTAL FORCE INSTRUMENT.

ELECTROMAGNETIC WAVES

Waves of associated electric and magnetic fields characterized by variations of the fields. The electric and magnetic fields are at right angles to each other and to the direction of propagation. The waves are propagated at the speed of light and are known as radio (Hertzian) waves, infrared rays, light, ultraviolet rays, X-rays, etc., depending on their frequencies.
