  • Three existing methods are compared,and a new ellipsoid expansion method considered ellipsoid misalignment is proposed based on analytic geometry theory.The influence on major semi-axis variation,station latitude variation and Gaussian Plain Coordinate caused by ellipsoid misalignment is examined.According to the experiments,the results from the proposed method and generalized geodesy derivation equation method agree well,and the proposed method is more intuitive.
