This paper describes the use of a fluxgate compass to provide accurate heading information for autonomous underwater vehicles. Two sources of error are identified: steady-state bias and compass lag. Results of field tests comparing a fluxgate and a reference heading indicate the compass has excellent dynamic performances when both bias and lag compensation are applied. Plans for further laboratory testing of magnetic compass dynamic characteristics are discussed.
