Abstract

In order to eliminate the systemic errors in the traditional methods of track calculating, the symbolic formulae of meridian arc´s forward and inverse solution are introduced, then Mercator sailing which could solve the problem of accurate track calculating is given. The calculation formula of Middle latitude is derived from its geometrical definition based on an elliptical earth, and then the precise middle latitude sailing method is available. Numerical examples show that the two methods derived by this paper could solve the problem of accurate track calculating under different reference ellipsoids in navigation.
