Research on Modeling Technology of High-Spin Projectiles with Geomagnetic Information

Abstract

This study introduces geomagnetic information related to attitude into the modeling process of high-spin ballistic projectiles. Measured values from geomagnetic sensors are utilized to calculate geomagnetic azimuth and angular rate. The relationship between geomagnetic azimuth, pitch angle, and yaw angle is described for trajectory modeling, providing a basis for aerodynamic parameter identification and 6-DOF trajectory simulation.
