| 摘 要： | 分析了传统的航迹计算方法存在的系统误差，引入了符号形式的子午线弧长正反解公式，推导出了可以消除该误差进而提高航迹计算精度的精确墨卡托航法。算例分析表明，该方法可以解决航海上不同地球参考椭球下的航迹计算问题，反解精度高达10^-4 m。

| Abstract: | The systematic errors in the traditional methods of track calculating are analyzed firstly,then the symbolic formulae of meridian arc's forward and inverse solution are introduced,finally the precise Mercator sailing method which could eliminate the systematic errors and improve the accuracy of track calculating is derived.Numerical examples show that this method could solve the problem of track calculating under different reference ellipsoids in navigation,and the precision of the inverse solution is up to... |
