Abstract
The paper describes a compact (50-cu cm) fiber-optic gyro (FOG) prototype with a dynamic range of +/- 1500 deg per sec and a bias stability of 1 deg per hour. The FOG uses an all-digital signal processing scheme which is intrinsically free of electronic bias drift, making it possible to work over the whole potential dynamic range of the FOG without degrading the bias performances. With a stability and a linearity of 10 ppm, this FOG is a good candidate for high-performance tactical-grade applications. A configuration scheme of the FOG prototype is presented.
