Digital Closed-loop Fiber Optic Gyroscopes - A Choice for Micro/Nano-Satellites Application

Two improved compact architectures of three-axes IFOG using sharing components and time division multiplexing with a new modulation method were proposed. The miniaturization techniques for configurations, electronics and optical components were demonstrated. And an efficient approach of parameters monitoring and fault diagnosis has been developed. Finally the new products, performance test results and their uses in several micro/nano-satellites were introduced.
