Angular Rate Sensor Development.

Abstract

This document is the final report on an effort whose objective was to deliver two prototype versions of the Kearfott Angular Rate Sensor (KARS). The KARS is basically a damped angular accelerometer. It comprises a conductive liquid annulus (Mercury) positioned in the gap of a permanent magnet. Upon application of an angular input to the case, the liquid annulus initially remains immobile. The relative motion of the liquid to the case is sensed by measurement of the potential generated in the liquid as it cuts the lines of force of the permanent magnet. The potential is measured on two electrodes submerged in the Mercury. As a result of this effort, two working prototype units were constructed, tested and delivered. (Author)
