As ships and maritime transport have evolved, knowledge of navigation methods has also evolved, reaching today modern means that require less of the skills and time of navigators to determine the position of the ship on sees and oceans. However, the IMO resolutions maintain the obligation for seafarers to know the procedure for deter-mining the position of the ship based on the use of astronomical position lines, a process known simply as the "Intercept Method". As is well known, the classical "Intercept Method" involves a graphical stage aimed to determine the geographical coordinate of Fix position. This paper presents a combined method which eliminates the graphical construction which may involve plotting errors. The method introduces mathematical computation of fix geographical coordinates.
