| Abstract: | An analysis of magnetic disturbance was made and the geomagnetism under different disturbance was discussed based on turntable tests. Geomagnetism compensation was also proposed by employing mathematic fitting to eliminate heading errors caused by fixed magnetic disturbance. The experimental results demonstrate that the fitting compensation can remove magnetic errors effectively and can provide stable heading with an accuracy of 2.00°. |
| Keywords: | electronic compass magnetic interference erroer compensation heading measurement attitude determination |
