Study on the Transformation Methods Between Rectangular Space Coordinate and Geodetic Coordinate

Aim\ To analyze the transformation methods between rectangular space coordinate and geodetic coordinate. Method\ Four iterative algorithm and one direct method were summarized and analyzed and one example is given. Results\ In the suggested four iterative algorithm,the forth method (using \%B→N→H\% iterative cycle) has the best precision. As comparing with the direct method,it has the same precision. Conclusion\ The study of GPS satellite positioning by analogy has some theoretic and practical value.
