← HistoryWhich outcome occurs on long sea voyages when a chronometer loses accuracy by a few seconds per day relative to GMT?
A)Longitudinal position error increases steadily✓
B)Latitudinal position becomes more questionable
C)Celestial navigation accuracy improves negligibly
D)Star visibility reduces over longitudes
💡 Explanation
Ephemeris calculations rely on accurate time-keeping; because a chronometer’s timing error accumulates linearly, `dead reckoning`, introduces longitude error; therefore, the position's east-west error increases steadily, rather than latitude because latitude is based on celestial angles regardless of time.
