| Abstract: |
| With the development of satellite control system technology, in-orbit life of satellites is increasingly improved. The designed life of follow-up medium and low earth orbit satellites is required to be5~8years, and that of high earth orbit satellites is required to be10~15years. As one of the critical parts of satellites, fiber-optic gyroscope is one of the main factors limiting the life and reliability of satellites. Form the reliability point of view, the technical features of fiber-optic gyroscopes was analyzed. Further suggestions to improve fiber-optic gyroscopes for long-life satellites were put forward. |
