A new method of fixing the position coordinates was presented in this paper. The ratio of distances was taken as a navigational isometer. It was proved that so defined navigational isometer is characterised by many advantages. The distances to seamarks can be measured both directly and indirectly, e.g. from hydroacoustic or radionavigational measurements and other. Having a limited knowledge of the signal propagation conditions, accuracy of the position coordinates can be increased, employing the ratio of distances. It follows in connection with elimination of this part of the errors which are proportional to measured distances. Moreover, results of the position accuracy analysis, considering the assumptions that were made, were described in the paper. Practical realisation of the naval hydroacoustic navigation system covering the Gulf of Gdańsk, was presented.
