“From Harrison to GPS” – Richard Easton at The Explorers Club, NYC

Public Lecture Series feat. Richard Easton – May 5, 2014 from The Explorers Club on Vimeo.

From Harrison to GPS – This lecture traces the development of navigation from the 18th century longitude problem to the invention of the Global Positioning System. Easton will describe the two major proposed solutions to the longitude problem: accurate clocks as developed by John Harrison and observations of celestial objects such as lunars and the Jovian moons. He will then trace the history of satellite navigation proposals culminating in GPS which combines the two 18th century proposals, putting accurate synchronized clocks in satellites which are artificial celestial objects.
