Fundamental limitations of rotational motion sensing for precision pointing applications
Abstract
This paper explores the underlying concepts used in the sensing of rotational motion and establishes fundamental limitations affecting the performance for precision pointing mechanizations. The paper further discusses bandwidth considerations, and the effects of these considerations on specific sensor implementations. Illustrative examples are presented, including representative gyro and inertial angle sensor candidates, to show how different concepts have been used to achieve the levels of performance available today and where improvements in performance may be possible. Among the limitations discussed are Brownian motion, turbulence effects, and electronics noise.
