Attitude and Velocity Estimation of a Projectile using Low Cost Magnetometers and Accelerometers

Abstract: A guided and controlled ammunition requires a performing navigation system. In this paper, an attitude and velocities estimation process is presented. It is based on a 3 axis magnetometer and 2 axis accelerometer. The estimation process is divided into 3 successive observers. Each observer is validated on simulations. Then the complete process is tested on free flight measurements. The results show that low cost sensors combined with a simplified 6 degrees of freedom projectile model are sufficient to estimate angular velocities without using the gyroscopes.
