Abstract: This paper deals with a direct method for computation of a ship's position from the observation of two selected stars without the need to use the altitude difference method known as the Marcq St. Hilaire method. The St. Hilaire method is the indirect one, since once the altitudes and azimuths of two celestial bodies have been computed, it is necesary to carry out an additional procedure (either graphical or mathematical) in order to obtain the coordinates of the observed position (intersection of the position lines). Thus, the availability of a direct method is of interest.
