墨卡托航行和大圆航线的微机计算法

Microcomputer-aided Calculation of Mercartor's Sailing and Great Circle Track

根据本文数学模型、程序,借助PC—1500微型计算机可以快速计算墨卡托航行（可连续求得推算船位,能求得预配流压差情况下的真航向和航速）、大圆航线和混合航线的问题。其计算精度较高,足以满足航海上的要求。

Using the mathematical and the programs presented in this paper, quick calculation can be made, on a micro-computer, PC-1500, of Mer-cartor's sailing (Dead reckoning can be done continuously and the true course and speed can oe found with the preset drifting) and of the Great Circle and the Compositive Tracks, with their accuracy up to the navigation requirements.
