In this paper, a novel approach is proposed to determine the ship position by combining the azimuth of a celestial body and the planning route of ship. Firstly, the equation relating the azimuth of observed body to the ship position in spherical coordinate system is described. Secondly, Mercator sailing method in the marine navigation is employed to to initialize the result of ship position. Finally, simple iterative method is applied to obtain the ship position.
