摘　　要：将地球视为椭球体,利用墨卡托投影理论建立恒向线正解与反解计算模型;通过对计算公式进行修正,实现跨180°经线计算。计算模型通过程序设计语言实现并被应用于航迹分析和航线分割;计算结果与文献资料和航测数据进行对比,验证模型的准确性。Based on the ellipsoid model of the earth,the calculation model of the forward and inverse solutions of rhumb-line’s problem were established by employing the Mercator projection theory.After modifying the computing formulas,the model was applied to the cases of crossing the antimeridian.The calculation model was realized by an original code and applied to track analysis and route segmentation.The results of the model were compared with the related literature and the real ship data.The accuracy of model was validated accordingly.
