摘要
一本文以航天领域中卫星上惯性敏感部件的应用为背景，对捷联式陀螺和加速度计的冗余设计进行了分析和研究，得出在待测三维姿态量的平均方差最小意义上的陀螺和加速度计的几何最优安装结构；并对这几种配置方案的非故障模式和故障模式（包含临界故障模式）所能达到的精度指标进行了分析和推导，并同常规的非冗余正交安装方案进行了对比；此外，对这几种配置方案在温备份和热备份工作状态下的可靠性指标的计算公式进行了推导，并给出了相应的应用条件。
In this paper we discuss the redundant design of strapdown gyro-scope and strapdown accelerometer referring to the applications of inertial units on man-made satellites in the aerospace field,and we get the optimal space mounting methods of gyroscope and accelerometer in the sense of acquiring the minimum mean variance of the three dimensional attitudes to be measured.At the same time we analyze and deduce the precision induces of these mounting methods in the non-failure modes and failure modes(include the edge-failure mode.On the other hand,we deduce the calculating formulas for reliability of these mounting methods under the conditions of warm-re-dundancy modes and hot-redundancy modes,and the application conditions for each method are also listed.
