1530年代,“在船或其他船隻上行駛的行爲”,源自法語 navigation(14世紀)或直接源自拉丁語 navigationem(主格 navigatio)“航行,導航,航行”,是 navigare “航行,越過,海上行駛,駕駛船隻”的動詞過去分詞詞幹的行動名詞,源自 navis “船”(源自 PIE 詞根 *nau- “船”)和 agere “啓動,驅動,向前驅動”的詞根(源自 PIE 詞根 *ag- “驅動,拉出或向外拉,移動”)。指“指導船隻航行的科學或藝術”始於1550年代。
The management of the sails, etc., the holding of the assigned course by proper steering, and the working of the ship generally pertain rather to seamanship, though necessary to successful navigation. The two fundamental problems of navigation are the determination of the ship's position at a given moment, and the decision of the most advantageous course to be steered in order to reach a given point. [Century Dictionary]
帆的管理等,通過適當的操舵保持指定的航向,以及船舶的工作通常更多地涉及航海技術,儘管這對於成功的導航是必要的。導航的兩個基本問題是在給定時刻確定船舶的位置,以及決定爲到達給定點而應採取的最有利的航線。[世紀詞典]
