A Unique Solution for Flight Body Angular Histories

Abstract

U.S. Patent 638155, Projectile Orientation In Navigation TERms (POINTER), was awarded in June 2002 for the design of a constellation of optical and magnetic devices and a processing methodology that provides a solution for the projectile pitch and yaw angular history. The POINTER solution is obtained from the simultaneous solution of a system of equations describing respective sensor output as functions of projectile orientation. Because one of these equations is quadratic, there are two possible solutions. An alternate set of simultaneous equations that yield a unique POINTER solution have been identified and is presented herein.
