| Abstract: | Based on the solution to univariate cubic equation, this paper puts forward a rigorous coordinate conversion method from Cartesian system to geodetic system. An example is given to validate this method. It can be used in practice in stead of the existing conversion methods which are on the basis of iteration procedure. |
