Which limitation constrained the accuracy of dead reckoning navigation before Harrison's chronometer?

💡 Explanation

Before accurate chronometers, longitude estimation depended on dead reckoning and distance estimation because longitude calculation requires very precise time knowledge, leading to cumulative error with each course change. Therefore the uncertainty was highest in longitude, rather than latitude or magnetic declination which relied primarily on celestial observations or magnetic compass variations.
