The Marine Chronometer

Before the mid-18th century, navigators were unable to accurately determine their longitude at sea. In an effort to encourage innovators to develop a method for precisely determining a ship’s longitude, the British government began offering a prize in 1714.

He spent the next 30 years improving his chronometer and was awarded a good deal of money as a result. What do ships use to navigate today? Discuss
