A Improved Single Axis Rotation Modulation Scheme of FOG Inertial Navigation System

在常规单轴两位置旋转调制方案基础上,提出了一种改进型光纤陀螺惯导系统单轴旋转调制方案,该方案深入研究了载体航向角变化时,通过优选惯性测量组合(IMU)的旋转停止位置,实现了比常规调制方案更好的导航误差自补偿效果。通过理论推导和仿真验证,证明了本方案的有效性、可行性。

In this paper,on the basis of traditional rotating modulation scheme,a improved fiber optic gyro inertial navigation system’s single axis rotation modulation scheme is raised.The scheme studied the changes of the head angle.Through the optimization of IMU stop position,the scheme realized a better error compensation effect than the traditional modulation scheme.This paper has carried on the theoretical derivation and simulation verification to prove the validity and feasibility of this scheme.
