Knowra History of navigation History of navigation The history of navigation traces how people developed and used methods, instruments, and systems to determine position and travel across land, sea, and air.
Celestial navigation : A method of determining position or direction by observing celestial bodies. The Sun, stars, and planets provided reference points when landmarks were out of sight.
Cartography : The practice and study of making maps. Maps recorded routes, coastlines, and geographic knowledge for later journeys.
Polynesian navigation : Traditional wayfinding practices used by Polynesian voyagers to navigate across the Pacific. Star paths, swells, winds, and wildlife supported long ocean crossings without instruments.
Maritime navigation : The practice of planning and conducting travel by water. Seafaring drove many of navigation's most influential instruments and methods.
Age of Discovery : The period of European overseas exploration and expansion from the fifteenth through seventeenth centuries. Improved ocean navigation enabled longer voyages and sustained European expansion overseas.
Dead reckoning : A method of estimating position by advancing from a known point using direction, speed, and elapsed time. It let travelers estimate their position between observations or known landmarks.
Geodesy : The science of measuring Earth's shape, orientation, and gravitational field. Accurate navigation depends on models of Earth and consistent coordinate systems.
Wayfinding : The process of orienting oneself and choosing routes through an environment. Navigation's earliest forms relied on learned routes and environmental cues.
Aviation navigation : The methods and systems used to determine an aircraft's position and route. Aircraft added radio aids, inertial systems, and satellite positioning to navigation.
Columbian exchange : The transfer of plants, animals, people, diseases, and culture between the Americas and Afro-Eurasia after 1492. Ocean routes made possible by navigation connected ecosystems and societies across continents.
