Two ways of determination of orthodromic interposition coordinates will be presented with the secant method. In the second, tangent method unit change of orthodromic course (?K) will be used.}, issn = {2083-6473}, publisher = {Gdynia Maritime University, Faculty of Navigation}, keywords = {Orthodromic Navigation, Loxodromic Navigation, Quadrant Navigation, Meridian Sailing, Marine Navigation, Orthodromic Course, Loxodromic Course} }
