Abstract:

There are many models of ballistics trajectories. The high-resolution 6-degree-of-freedom 6-DOF models require many computations and a small time increment. The modified point mass models ignore the spinning of the round to reduce the computational requirements. Selecting a model to use for ballistics estimation or tracking requires tradeoffs between system accuracy and computation expense. The purpose of this report is to present reduced state models simpler than the 6-DOF model that can be used to model the trajectories using an extended Kalman filter. These filters can be used to enhance the performance of smart munitions.
