中国古代的航海技术便十分发达。拥有多种在当时世界居于领先水平的航海技术。中国的天文航海技术发展历程有据可查.西汉时代的《淮南子》便记载着中国古代航海家以北极星来辨别海上的方向。这便是后世以在海上观测天体决定船舶位置的天文航海技术的雏形。晋代葛洪的《抱朴子》一书中也说.如果在云梦大泽中迷失了方向.便需要靠指南车来指明方向.如果是在大海中迷失航向,则要靠北极星所在的方位来找到正确的方向。直到北宋之前,我国古代的航海家们还是靠着太阳与星辰来辨别方向。到了宋代。航海技术取得了划时代的进步——由司南演变而来的指南针被发明出来了。
Ancient Chinese navigation technology is very developed. Has a variety of navigation technology in the world leading level. The development of astronomical navigation technology in China is well documented.The “Huainanzi” in the Western Han Dynasty recorded the direction of the Polaris by ancient Chinese navigators. This is the embryonic form of astronomical navigation technology for determining the location of the ship by later observing the celestial bodies at sea. Ge Hong’s “Baopuzi” also said in his book that if you lost your way in the Dazhu Yunmeng direction, you would need to specify the direction by the guide car. If you lose your course in the sea, Directions to find the right direction. Until the Northern Song Dynasty, China’s ancient navigators still rely on the sun and stars to identify the direction. To the Song Dynasty. Navigational technology has made epoch-making progress - the Compass, evolved from Division South, was invented.
