KINEMATICS OF A TRACKING GIMBAL,

Abstract

This paper presents formulas for angular displacements, velocities, accelerations, and torques required about the individual axes of a two-axis gimbal system in which a tracking device swivels universally in error-free tracking of any specified tactic of an unaccelerated target. These formulas apply, for example, to missile and satellite trackers, theodolites, optical sights of weapons, and -- by extension -- to the weapon itself, displaced through a lead angle. The target can move in any direction through space, air, water, or on the ground. The gimbal system is carried on an unaccelerated platform and the pintle may be oriented any fixed spatial direction. The effect of target tactics on the choice of gimbal orientation is discussed, particularly in its effects on smoothness and speed of tracking. (Author)
