摘　　要：综述了空间飞行器的精密定轨对世界时测量的需求,并对现有大型激光陀螺、光纤陀螺测量世界时的现状与前景进行了分析,阐述了大型高精度光纤陀螺用于世界时测量需重点解决的关键技术,对实现的大型高精度光纤陀螺样机进行了试验验证,零偏不稳定性达到了5.2×10^(-6)(°)/h(1σ),同时对陀螺长期运行期间探测到的青海玛多地震情况进行了分析,最后对面向更高精度的世界时测量用大型光纤陀螺发展方向进行了展望。The requirement of high-precision orbit determination of spacecraft for universal time measurement is summarized, and the current research status and prospects of the existing large-scale laser gyroscopes and fiber optic gyroscopes(FOG) for universal time measurement are analyzed. The key technologies of large-scale high-precision FOG for universal time measurement are detailed described. The performance of high-precision FOG prototype realized in this paper is experimentally studied, and the bias instability is 5.2×10^(-6)(°)/h(1σ). At the same time, the Maduo earthquake in Qinghai province detected by the gyroscope during its long-term operation is analyzed. Finally, the development direction of large-scale FOG for higher-precision universal time measurement is prospected.
