Abstract : This report describes an applied research effort with the specific objective of determining and demonstrating the practical feasibility of using the solid state gyroscope as a vehicle stabilization sensor. The solid state gyroscope is a monolithic configuration of a vibrating gyroscope device. The sensing element is a polycrystalline piezoelectric ceramic cylinder which has been selectively polarized such that it is the equivalent of a self-driven spring-mass system and is its own output signal generator. Basic characteristics such as the zero angular rate null signal, which adversely influence the stability and the sensitivity of the instrument, have been investigated. Feasibility models have been designed and fabricated and have undergone both performance and environmental evaluations. The results provide a clear determination of the feasibility of the technique for sensing both high and low angular rates while utilizing an extremely small volume, power consumption, weight, and having a maximum reliability. Applications, as well as areas in which future research endeavors should be concentrated, are discussed. (Author)
