← HistoryWhich consequence results when excessive 'dip' exists when using a sextant at sea?
A)Inaccurate celestial altitude measurements✓
B)Overestimation of ship's latitude
C)Chronometer synchronization failure
D)Deformation of lens and mirrors
💡 Explanation
Inaccurate measures occurs because refraction causes the observed horizon to appear higher than its geometric position; this error is the Dip of the Horizon. Because it increases altitude angles, therefore navigational calculations become flawed, rather than causing instrument or timing malfunctions.
