Abstract

In the geomagnetic navigation system of a common projectile, the vehicle's magnetic field is a main factor affecting the measurement accuracy of geomagnetic sensor. In order to eliminate or compensate the interference, the distribution of vehicle's magnetic field needs to be studied. In this paper, the magnetic equation was solved with magnetic scalar method. Three-dimensional static magnetic field simulation technology was studied. Numerical solution of magnetic induction distribution in the projectile was obtained by the finite element tool of ANSYS. The change rule of magnetic induction in the projectile with an external uniform magnetic field was analyzed through the contour plot and data curve.

Key words： geomagnetic navigation; vehicle's magnetic field; magnetic scalar method; ANSYS; uniform magnetic field
