Evidence suggests that the magnetic compass was invented in China between 221 and 206 B.C. The earliest compasses were not used for navigation, but for fortune-telling. Chinese compasses became navigational orienteering devices between 1040 and 1044 A.D. and were used as maritime navigational devices by 1117 A.D.
This navigation aid was invented in 1912 by Donald M. Bliss (read Wikipedia) and improved and patented in 1924 by Morris Titterington, founder of PIONEER Co. This compass type equipped the Spirit of St. Louis when Charles Lindbergh flew from New York to Paris in 1927.e display here just a few examples: The model 06A, a landing compass was a hand bearing compass for use on the ground (for modern instruments see SESTREL, SAURA). Other compasses installed on-board of aircraft were based on a same design like the P series.
