CALCULATION OF NAVIGATIONAL PARAMETERS IN MERIDIAN, EQUATOR AND PARALLEL SAILING BY MEANS OF RELATIVE COORDINATES AND CORRELATION FACTORS

Serđo Kos

Abstract

Meridian, equator and parallel sailing are seen as special sailing due to general regularity that can be unequivocally defined by relative coordinates  and . Based on the relative coordinates  and , and the correlation factors (1, 2, 3, 4), this paper infers equations for calculating the distance a vessel sails across the Meridian, Equator and Parallel, on
condition that the Earth is approximated by the sphere of the unit radius R1, selected radius R or selected ellipsoid determined by the semi-axes a and b.
The detailed method of determining the loxodrome course is explained on the basis of the sign of the corresponding relative coordinate. The result is completely defined navigational parameters for Meridian, Equator and Parallel sailing.

Keywords
