History

Which positional error increased for early Royal Navy ships relying on dead reckoning after protracted voyages?

A)Inaccurate compass bearing alignment
B)Accumulated longditude calculation error
C)Sextant altitude measurement discrepancy
D)Chronometer time synchronization drift

💡 Explanation

Early navigation relied on estimated speed and course, but longitude calculations suffered from accumulated error over time because accurate chronometers were unavailable, therefore ships often arrived far from intended locations, rather than errors strictly in bearing or altitude at points.
