← HistoryWhich navigation error grows significantly when utilizing sextants at higher latitudes?
A)Refraction errors near the horizon✓
B)Parallax errors from lunar observation
C)Instrumental errors from thermal expansion
D)Time errors impacting celestial calculations
💡 Explanation
When using sextants at higher latitudes, the angle to the horizon becomes shallower causing a greater atmospheric path length which amplifies refraction errors because atmospheric density changes. Therefore refraction errors become significant, rather than parallax, thermal, or timing errors, as they are less dependent on latitude.
