Dead reckoning is an ancient navigation method used by early mariners and explorers.
Before modern technology, navigators determined their current position by estimating direction and distance from a known point.
This technique was widely used during the Star Age, when celestial navigation with stars and dead reckoning helped sailors cross oceans.
They combined star positions with compass headings and estimated speeds to chart their courses.
Thus, the Star Age is associated with the use of the dead reckoning process.
