A Ballistic Filter for GPS and Accelerometer Measurements
Abstract
This report extends the work of Andrew A. Thompson described in the report titled Ballistics Filtering, ARL-TR-4735, published in March 2009, by showing the process of realizing the ideas through a simulation. By providing a concrete example it is hoped other realizations of the ideas can be pursued with a reasonable effort. Ballistic Filtering describes the dynamic equations that can be used to form Extended Kalman Filters (EKF) for the estimation of a projectile's trajectory. The steps associated with initialization and implementing an EKF are demonstrated through a specific task. The performance of an EKF processing Global Positioning System (GPS) observations is compared to the performance of an EKF processing both GPS and axial accelerometer observations.
