ATTITUDE ESTIMATION AND PRECISION GUIDANCE OF A SPINNING ARTILLERY SHELL

Abstract

Guided munitions enable precise targeting and minimal collateral damage. Accurately determining an artillery shell’s orientation in flight allows real-time trajectory adjustments for maximum effectiveness. Spinning enhances stability but complicates attitude estimation due to dynamic disturbances. This research explores cost-effective techniques to estimate the attitude of spinning artillery shells using a magnetometer, accelerometer, GPS, and gyroscope integrated into a Kalman filter framework. The estimated orientation (roll, pitch, yaw) enables real-time trajectory corrections. A guidance algorithm will refine the shell’s path based on its position, orientation, and target coordinates. This system is critical for modern defense, allowing remote-launched munitions to strike with high precision while reducing costs. By continuously adjusting deviations from the intended flight path, it enhances accuracy and aligns with advanced military strategies focused on precision and efficiency.
