摘要
将影响 IMU误差系数漂移并难于分离的多种因素综合为一种因素 ,假定 IMU误差系数的漂移由一特定系统所引起 ,从而采用时间序列建模方法进行 IMU误差系数漂移的预测。该方法具有消除各因素具体分析中的不确定性并减少其工作量的优点。文中描述了其原理 ,对某惯组的 3 3个误差系数进行了时间序列建模与预测并得到有效的结果。
Multi factors effecting the shift of IMU error coefficients and being hard to extract are synthesized to one factor, and a certain system is assumed to cause the shift of IMU error coefficients, thereby the time sequence modeling is adopted to predict the shift of IMU error coefficients and in this way the indeterminacy in the factors analysis can be eliminated and the workload can be reduced. The principle is given here, and 33 error coefficients of a certain IMU are effectively predicted with time sequence modeling. The remaining problems and the corresponding resolutions are given at last.
