Abstract :
Fiber optic gyroscopes (FOG´s) have progressed to a state where they are now being used in various 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 communication fiber for the rate sensing element. This design is similar to the FOG used in the Standard Compass/Attitude Heading Reference System (C/AHRS). Testing consisted of static and dynamic baseline tests, input axis alignment tests, static and dynamic temperature and magnetic field testing. This presents an overview of the FOG design and a discussion of the test results
