等角航线-
为了克服计算航法在地球圆球体上解算精度低的缺点，研究了地球椭圆体面上进行等角航线（恒向线）正、反解算的理论，并以算例进行校核。
For overcoming the defect of the low solution accuracy of computing navigational method on circle earth the normal and inverse solutions of conformal course ( rhumb line ) on the ellipsoid are studied in the paper and checked by examples as well .
