Abstract: Fiber optic gyroscopes (FOG) have now been widely used in space vehicles due to the advantages of all solid-state, long lifetime, high reliability and well adaptability to space harsh environment. In China, FOGs started to be deployed in aerospace vehicles since the beginning of 21st century. It makes a significant contribution to the improvement of performances of chinese spacecrafts including navigation satellites, communication satellites, remote sensing satellites, manned spacecraft and lunar exploration vehicle. In this paper, applications of several FOGs are introduced focusing on different design schemes. New types of fiber optic gyroscopes, such as photonic crystal, are investigated with regart to their characteristics in space applications. Key technology solutions to meeting special requirements of space applications as well as their future developments are discussed in the end.

Key words: fiber optic gyroscope(FOG), space application, design scheme, key technology
