【Abstract】 In this paper,we point out some of the limitations of the traditional Bessel’s formular based algorithm of inverse solution of geodetic problem and present an improved algorithm to combat such deficiencies.Compared with the traditional algorithm,the improved algorithm has the advantages of no oddity,easy computing and programming.We also point that Bessel’s mapping is not an isomorphic mapping.So it is impossible to fit to arbitrary distance of inverse solution geodetic problem.更多还原
