Abstract

We report the construction and performance of several prototypes of a low-cost 3-axis fiber gyro using an electronic phase tracking scheme to provide a post-sensing closed loop operation. These gyros exhibit an output nonlinearity of < 0.1% in our rate tests from 0 to 200 deg/sec, a noise level < 10 deg/hr in a 1 Hz bandwidth, and a thermal dependence of the bias offset approaching 1 (deg/hr)/deg C.
