Abstract

In geomagnetic navigation system, the shielding of projectile has a great effect on measurement of the magnetic sensor. So, in order to compensate the error, the software of ANSYS was adopted to research the shielding coefficient of projectile body in this paper. First of all, an introduction to the theory of geomagnetic field shielding coefficient was given to get the theory value, then the experimental value was got by ANSYS software, finally, the influence of permeability on the projectile magnetic shielding coefficient was analyzed. Through comparison, the result shows that the error of the experimental value and the theoretical value is very small, so the feasibility of using ANSYS can be verified to analyze the projectile magnetic shielding effectiveness.

Key words： geomagnetic navigation system; projectile magnetic shielding effectiveness; path analysis; finite element analysis
