Aerospace | 1. Angular distance north or south of the celestial equator; the arc of an hour circle between the celestial equator and a point on the celestial sphere, measured northward or southward from the celestial equator through 90 degrees, and labeled N or S to indicate the direction of measurement.2. (Symbol D) Magnetic declination. See equatorial system. (references) |

Energy | The angular position of the sun at solar noon with respect to the plane of the equator. (references) |
Mining | A. The horizontal angle in any given location between true north and magnetic north; it is one of the magnetic elements. Syn:variation; magnetic variation b. Angular elevation of a star above celestial equator when truly north of observer c. Angular deviation of magnetic compass from true north, observed in conditions where no local deviation affects it d. The angular change in the course of a borehole induced by deflection techniques, usually expressed in degrees. (references) |
Physics | A coordinate which, along with right ascension, may be used to locate any position in the sky. Declination is analogous to latitude for locating positions on the Earth. (references) |
Science | The angular distance from the equator to the satellite, measured as positive north and negative south. (references) |
Space | One of the two angles uses to specify location on the celestial sphere. Declination is like latitude, but unlike latitude, it is measured from the north pole. The pole has declination 0, the equator 90 degrees, the southern celestial pole 180 degrees. See right ascension and declination. (references) |
| The measure of a celestial body's apparent height above or below the celestial equator. (references) | |
Transportation | The angular distance north(+)or south(-)from the celestial equator of an object located on the celestial sphere, measured along the hour circle passing through the object. Source: European Union. (references) |

(From Wikipedia, the free Encyclopedia)
Declination (dec) is an astronomical term associated with the equatorial coordinate system. Dec is comparable to latitude, projected unto the celestial sphere, and is measured in degrees north of the celestial equator. Therefore, points north of the celestial equator have positive declination, while those to the south have negative declination.
