In order to realize the tracking of ocean going ships,firstly, the space parameters of the great ellipse route were determined according to the starting point and end point of the route, and ellipse arc length formula was inversely solved by using the symbolic iteration method to acquire the corresponding centrifugal angle of the ship in the great elliptical route .Then, the auxiliary space rectangular coordinate system was established based on the great ellipse route, and the ship position was converted to the Earch Ellipsoid by the coordinate system rotation, so as to realize the ship position estimation process based on the great elliptical route.Finally, two routes were taken as examples to verify the effectiveness of the algorithm in ship position estimation at any time. It can provide a reference for the position estimation of ocean going ships to a certain extent only need to know the starting point, the end point and the speed of the ship.
