Historical Naval Navigation and Timekeeping

Subject: Static GK (General Knowledge)

Book: General Time Knowledge

For centuries, sailors relied on accurate timekeeping to determine longitude at sea. John Harrison’s chronometer, invented in the 18th century, revolutionized navigation by maintaining consistent time despite ship movements and temperature changes. This innovation saved countless lives and fostered global exploration and trade. Today, GPS and advanced instrumentation handle tasks once managed by these painstakingly built clocks. But the legacy remains, illustrating how essential precise time was to conquering oceans and charting previously unknown territories.
