摘　　要：提出一种带连续稳定旋转平台的新型光纤捷联惯性导航系统,旨在提高系统导航精度的同时,不增加惯导系统的成本。研究该惯导系统的组成结构和工作原理,分析旋转光纤捷联惯性导航系统误差调制过程,最后对整套惯性导航系统进行仿真。仿真结果表明,改进后的旋转光纤捷联惯性导航方案能够使惯性导航系统的精度提高一个数量级左右而不增加成本,因此具有重要的工程应用价值。A newly fiber-optic strap-down inertial navigation system with a continuous rotating disk was presented, aimed at improving the performance without adding the cost. Take a research of the technique and performance analysis of such a fiber-optic strapdown inertia[ system with a continuous rotating disk, providing the platform＇s composition and principle. Besides, the specific processes of error modifications are given as well. Simulation results indicate that, compared with the conventional method, the proposed approach attenuates the navigation errors by modulation of errors.
