Compass These numbers allow the compass to show azimuths or bearings, which are commonly stated in this notation. The magnetic compass was first invented as a device for divination as early as the Chinese Han Dynasty (since about 206 BC), and later adopted for navigation by the Song Dynasty Chinese during the 11th century.The use of a compass is recorded in Western Europe and in Persia around the early 13th century.his is an approximation of a milli-radian (6283 per circle), in which the compass dial is spaced into 6400 units or mils for additional precision when measuring angles, laying artillery, etc. The value to the military is that one angular mil subtends approximately one metre at a distance of one kilometer.

When Was the Compass Invented? The truth is, there was no such thing as the compass in ancient times, and even after the compass was invented, it wasn’t used all that much for marine navigation. Sailors in ancient times charted their course by the stars, and did not use a compass. No one knows where or when the first compass was invented. It may have been in China or in the Near East or in Italy. All we know is that the compass was first mentioned in the 12th century, and that it was first used on a European ship in 1345. These early compasses consisted of an iron needle attached to a piece of wood or cork that floated in a bowl of water. It wasn’t until the 19th century that a really dependable compass was invented. But the compass is no longer used on ships, it’s been replaced by a much better device called the gyrocompass.
