説明

Fixing by two horizontal angles has some remarkable features. It enables to determine ship's position at coastal area without special navigational instruments such as a radar or a compass. However, this method is seldom used because the procedure of measuring horizontal angles by a sextant and determining the position by a station pointer is considerably bothersome. Authors made experiments to validate the measured horizontal angle of selected objects on a photograph satisfies the requirement for fixing a position in coastal area. Some problems are found to be solved hereafter, but the result suggests this method to be feasible, we believe. New methods to determine the position by calculation are also proposed.
