Abstract
Fiber optic gyros of modest performance can be used as angular rate sensors for vehicle navigation on land. A practical design uses an open-loop configuration with an all-fiber optical system together with analog signal processing, which makes for low cost and simple construction. Initial production has started on a gyro whose principal components are all made from elliptical-core polarization holding fiber. The angle random walk is less than 10 deg/hr/rt-Hz with a maximum input rate of 100 deg/sec. The output is either an analog voltage which is proportional to rate or serial asynchronous data representing an incremental change in angle.Keywords
