摘要
以地球椭圆体为基础,通过理论公式推导,得出了船舶东西向航行、南北向航行及其他航向航行时恒向线航线的航向和航程的精确计算数学模型.介绍了在各种情况下恒向线航向和航程的求取方法,航向以圆周法度量,航程统一到以法定海里为单位,并给出计算流程框图,便于计算机自动进行航迹推算.该航迹计算模型有较广泛的适用性,无论赤道一侧航行或跨赤道航行均能适用.
Based on spheroid, mathematical model of accurate calculation of both the course and distance in rhumb line is proposed in this paper, by theoretical approach with formulae, when ship sails along latitude, longitude and the others. The solutions to the precise sailing under above three different conditions are introduced, the course shown in clockwise and the distance in conventional nautical mile. The flow chart of the calculation procedure is chalked out so that computer can perform such calculations. The model of calculation can be used whenever ship sails on hemisphere or across the earth's equator.
