Which navigational error increases through prolonged periods of cloud cover when navigating with an 18th-century sextant?

💡 Explanation

A lack of celestial observation forces reliance on dead reckoning, accumulating position error because Estimating position relies on speed, time, and course calculations; therefore the uncertainty in estimated position grows, rather than direct observation correcting the heading.
