| 摘 要： | 从频域角度分析了捷联惯导系统在姿态解算过程中误差产生的原因，并在典型圆锥运动情况下进行了定量计算．结果表明，由于采样和量化过程中的误差，使惯导系统输出的姿态角出现了耦合误差，并提出了对采样信号进行预处理即设计滤波函数以减小采样信号失真的观点．

| Abstract: | This paper analyzes the cause of the error of attitude algorithm of SINS in frequence domain, and computes the error under the classic conic motion. The result shows that the error in sample and quantization causes coupling error in the output of attitude in SINS. Also the paper points that the preprocess of sample signals is the course of designing the filter function and this will reduce the distort of sample signals. |
