摘　　要：北冰洋特殊的航行环境给天文导航方法的应用带来了特殊困难。本文基于对北冰洋与天文导航相关的特殊航行环境,即气象、海洋、地理、天象和光照环境及其对天文导航影响的分析,探讨北冰洋航行天文观测、天文定位和天文定向存在的具体问题,并从技术、操作和设备等方面给出相应的解决对策,可为我国开展北冰洋航行提供有益的借鉴。Special navigational environments using celestial navigation. Based on the analysis of navigation in the arctic ocean, such as the weather, of arctic navigation lead to special difficulties when special navigational environments related to celestial the ocean condition, the geographical condition, the apparent motion of celestial bodies and the illumination condition, the special difficulties when using celestial navigation is discussed and the solutions of celestial observation, celestial fix and celestial direction determination are given.
