This book explores the Galilean method for geolocation, placing it in historical and astronomical context. It bridges the techniques developed by the Greeks and medieval astronomers with later innovations like precision clocks, 20th-century wireless technology, and space-based navigation.
The primary source is the twenty-volume National Edition of the Works of Galileo (published 1890-1909 by Antonio Favaro) and the update edited by Michele Camerota and Patrizia Ruffo in 2019, which includes previously unpublished documents on Galileo's negotiations with the Spanish government for selling his longitude-determining method at sea.
This book inspired the 2024 \"International Research Day in the World
