Abstract
With rapid development of electronics, the miniturized digital computer will be equipped on a ship near future. Under necessities of astronomical navigation with a digital computer, programs of distance and initial and final cources have been set up and tested between two points on the great circle. According to HITAC 5020 (FORTRAN IV), compilation requires 7sec., and computation 0.2sec. each set of the distance and the cources. Computation is executed in 7-figure, the accuracy will be sufficient for astronomical obsernations at sea.
