摘要
介绍了高纬海区天文观测的特点及在极区航行天文定位的方法,提供了采用计算机来解算天文观测船位的步骤,从而使高纬海区天文定位方便可行。同时也为全球天文观测计算机定位提供了参考。
A sruvey is made of the characteristics if astronomical observation is sea regions of high latitudes and the methods of celestial navigation in the polar regions. Steps are provided for computer-aided calculation of the ship' s position obtained by astro-observation, thus making feasible the astronomical position-fixing in sea regions of high latitudes and serving as a useful reference for global computer-aided position-fixing through astronomical observation.
