| Abstract: | According to the solution of spherical harmonics associated with the magnetic field of the Earth,and the actual situation of our sea area,an auto-correction technique has been given to correct the deviation of magnetic direction. The results,which can be used in underwater direction,are keeping well with the chart materials provided by national survey departmant. |
