Abstract

An inertial-grade interferometric fiber optics gyroscope (IFOG) was developed for potential use in NASA deep-space missions. The closed-loop IFOG system, which incorporates beat detection circuitry exhibits the best measured long-term bias drift of 0.0016 deg/hour. The key component of the system is an advanced 13-component LiNbO3 integrated optical circuit (IOC) fabricated by annealed proton exchange process.
