Comments

A fix is simply the determined position of a ship at sea at a given time. It can be determined using various methods, such a the observation of landmarks, celestial, radio, or satellite. The accuracy of a fix can vary depending on the method(s) used. Modern satellite fixes determine a position within a few feet, whereas older celestial or radio fixes can be off by much larger amounts.
