Central Inertial Guidance Test Facility (CIGTF) Testing of a Depolarized Fiber Optic Gyro Inertial Sensor Assembly

Jerry Page and Daniel Sugarbaker

Abstract:	Fiber Optic Gyroscopes (FOG’s) have progressed to a state where they are now being used in a variety of missile and aircraft attitude reference systems. The majority of these systems utilize polarization preserving fiber in the ring. This paper presents the design and test results for an innovative single axis FOG which uses commercially available commuuication fiber for the rate sensing element. Thorough testing of a single axis unit at the Central Inertial Guidance Test Facility (CIGTF) at Holloman Aii Force Base, New Mexico, U.S.A. followed by Smiths Industries testing of a triad of gyros integrated in an Inertial Sensor Assembly (ISA) has demonstrated performauce superior to the 1 degree per hour design requirement. Testing consisted of static and dynamic baseline tests, input axis alignment tests, static and dynamic temperature and magnetic field testing. This paper presents an overview of the FOG design and a discussion of the test results.
