Abstract
The fundamental requirement of today's munition systems is the greatest lethality with minimal collateral damage. A guidance, navigation, and control (GNC) system is critical to meeting this requirement. Accurate, novel projectile navigation systems must meet the steep requirements imposed by gun launched projectiles. Development of projectile navigation systems requires a multidisciplinary background in the fields of estimation theory, dynamic systems, and aerodynamics. In this dissertation, the fundamental theory of projectile flight dynamic modeling is presented and applied to the navigation problem. The modeling and processing of magnetometers, devices that measure the direction and magnitude of the applied magnetic field, is derived. The magnetometer processing techniques are combined with the flight dynamic modeling to create projectile state estimators. The estimators are applied to specific projectile trajectories to demonstrate their performance.
