THE METHOD OF IMPROVING THE ACCURACY OF SHIP POSITION DETERMINED BY DEAD RECKONING USING A CIRCLE OF EQUAL ALTITUDE

Abstract

In this paper, the theory of method to improve the accuracy of ship is proposed by using a circle of equal altitude of a single celestial body. On the proposed method, the accuracy of dead reckoning-determined ship position is enhanced when land marks are invisible. In addition, this method can be also used to find out the ship position when there is only a single celestial body observed.
