【摘要】 主要研究了捷联式惯导系统冗余配置陀螺仪的配置数目、配置结构对导航系统可靠性的影响.同时,分析了在确定陀螺仪数目后,通过优化配置结构可使捷联式惯导系统获得最佳的导航性能和最优的故障检测性能,并导出一些相关的结论.最后以四个双自由度陀螺半八面体配置为例说明了结论的正确性.更多还原

【Abstract】 The number of gyros and gyro structure′s configuration will affect the performance and reliability of strap-down navigation system heavily.The optimal configuration of redundant gyro is solved according to the optimal navigation and measurement performance when the number of gyros is decided.And then,some conclusions can be drawn from this paper.At last,an octanedron array of four TDOF(two degree-of-freedom)gyros as a example explains those conclusions.更多还原
