| 摘 要： | 提高惯导系统对于惯性器件误差负面影响的抑制能力,对于改善系统的导航精度具有重要意义.本文对惯导系统误差方程进行分析,重点讨论对称位置上惯性器件误差的积累效果,系统地研究了单轴旋转调制对捷联惯性导航系统惯性器件误差的自动补偿机理,详细分析了单轴旋转对惯性器件常值误差、标度因数误差的抑制情况.对单轴旋转调制方案进行仿真,验证了理论分析的正确性.

| Abstract: | It is significantly important to improve the performance of inertial navigation system navigation by controlling the negative effects on inertial navigation system for inertial measurement units.This paper analyses the error equations of the inertial navigation system,makes a focus on the inertial components accumulation effect on symmetrical position error,analyses the automatic constant error compensation mechanism of the inertial navigation system,and then discusses the error depressing of inertial components constant error,the scale factor error cased by rotating.Finally,the simulation for single-axis rotation mechanism validates the theory analysis. |
