LONG ZHANG, YAN ZHANG, YI DING, PENG WANG

Abstract


This article studied the application of geomagnetic sensor in projectile attitude test, by using the dynamic signal data of projectile flight acquired from projectile-borne geomagnetic sensor, combined with projectile attitude motion model, created a method of measuring the projectile-borne geomagnetic signal and acquired the angle motion parameters of projectile in whole trajectory, then acquired the spin angular velocity attenuate law of the projectile and the whole trajectory projectile nutation angle change by analyzing the angle motion parameters. The research shows that the projectile angle motion parameters can be acquired from projectile-borne geomagnetic sensor test, which being comparative analyzed with projectile angle motion characteristics, come to the analysis of the stability and disturbance characteristics of projectile flight.
