The History of Navigation

Modern travelers by land, sea, and air rely on accurate navigation without thinking about it, but this capability developed gradually over time. Dag Pike, a highly experienced sailor, traces the development of navigational techniques from five thousand years ago to the present day. Early explorers venturing into unknown waters depended on the sun and stars for direction. Over time, navigators adopted mathematical methods, astrolabes, sextants, and increasingly precise clocks to measure latitude and later longitude. Recent decades have brought major advances through electronic navigation systems, GPS, and satellite technology that have transformed travel. Focusing primarily on marine navigation while also covering other forms of travel, Pike examines both the successes and failures in humanity's efforts to explore the world. The work combines entertainment with detailed information about navigation's history.
