Question
History

Which consequence arose when the earlier mariner's astrolabe was replaced by the octant during 18th-century navigation?

A)Smaller observed solar altitude errors
B)Increased instrument manufacturing complexity
C)Greater susceptibility to thermal expansion
D)Decreased sensitivity to observer motion

💡 Explanation

Navigation accuracy improved at sea because the double reflection principal in the octant corrected observational errors, therefore yielding a more stable and reliable measurement, rather than persisting inherent errors caused by the single sighting plane on the astrolabe.
