光纤陀螺高可靠、长寿命保证技术探讨

High Reliability and Long Lifetime Guarantee Technology of Fiber-optic Gyroscopes

随着卫星控制系统技术的不断发展,卫星在轨寿命的要求不断提高。后续中低轨卫星普遍设计寿命要求达到5-8 a,高轨卫星设计寿命要求达到10-15 a。光纤陀螺作为卫星的一项关键部件,是目前制约我国卫星寿命和可靠性的主要瓶颈之一。从可靠性角度,对光纤陀螺的技术特点进行了分析,提出了适用于长寿命卫星平台的光纤陀螺的建议。

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 be 5-8 years,and that of high earth orbit satellites is required to be 10-15 years.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.
