摘　　要：将地球视为椭球体,利用贝塞尔投影理论建立大地线长度计算模型。修正原始公式,使算法适用于跨赤道和跨180°经线计算。通过与文献资料对比验证计算模型的准确性。将计算模型应用于智能船数据分析,讨论气象预报的准确度。The earth was regarded as an ellipsoid,and the calculation model was established to solve the geodetic-distance problem by employing the Bessel’s mapping.The original formulas were modified so that the algorithm could be applied to the cases of crossing the equator or the antimeridian.The accuracy of the model was validated by comparing with the related literature.The calculation model was applied and the accuracy of meteorological forecast was discussed.
