摘　　要：光纤陀螺定位定向导航系统在某型车辆动态跑车试验过程中出现了共振现象,引起导航误差大,因此,对系统结构进行优化、改进并采用合理的减振设计,模拟试验和实际跑车试验结果表明,系统精度得到改善,达到了设计指标,满足了总体要求,该系统可应用于其他陆用车辆导航和火力控制。The resonance was emerged during the outdoor vehicle experiment of the fiber optic gyro position and azimuth determining system, thus brought about relatively great errors. The system structure has been optimized, improved and a reasonable vibration-dampening design has been employed in this work. The simulation results and the outdoor vehicle experiment show that the system accuracy has been improved and satisfied the overall require- ments. The improved system can be used to other vehicles and the fire control system.
