大地线临界点和赤交点位置的确定

Determinning the Critical Point and the Equator Crossing of a Geodesic

  • 摘要: 本文专论大地线的临界点与赤交点,给出用嵌套系数精确求定其位置的方法。并以算例结果表明其精度。

     

    Abstract: In this paper,the two special points of a geodesic is described:The critical point and the equator crossing are defined by some special terms respectively.The positions of the critical point and the equator crossing of a geodesic are determined with the nested coefficient method.Finally the accuracies of the positions are shown by some prectical examples computed.
