Attitude Determination With Magnetometers for Gun-Launched Munitions

Abstract

Recent advances in digital signal processors (DSPs) and low cost sensing technology provide the capability for on-board attitude (orientation) determination for gun-launched projectiles. A complete. real-time solution for all three Euler angles (azimuth, elevation, and roll) that describes a projectile's attitude is presented, which uses magnetometers and angular rate sensors processed by a DSP. Unlike attitude estimation systems that rely exclusively on costly rate gyroscopes. magnetometers are used to stabilize drift errors. The proposed system fulfills the requirements of passive sensing, high-g survivability, small size, low cost, and low power.
