单轴旋转惯导系统误差特性分析

旋转调制技术能够抑制陀螺和加速度计的误差，提高惯性导航系统的导航精度。从捷联惯导系统的误差方程出发，推到出了单轴旋转惯导系统的误差传播方程，在此基础上分析了旋转调制的基本原理。分别对陀螺和加速度计常值偏差、标度因数误差、安装误差和转台安装误差等在旋转调制下的影响进行了研究，仿真分析了旋转调制提高系统导航精度的作用，最后在实验室条件下做静止导航实验进行了验证。研究的结果能为单轴旋转惯导系统的研究和开发提供一定的理论参考。

Uniaxial Rotation Inertial Navigation System Error Performance Analysis

Rotation modulation technique to suppress the error of gyroscopes and accelerometers, inertial navigation system navigation accuracy. Starting from the error equation of the SINS system onto a single-axis rotation error propagation equation of inertial navigation system on the basis of this analysis the basic principle of the rotation modulation.Respectively constant gyro and accelerometer bias, scale factor errors, installation errors and the turntable installation error in the rotation modulation has been studied, the simulation analysis of the role of the rotation modulation to improve navigation accuracy, and finally, under laboratory conditionsdo static navigation experiments verified. The results of the study for research and development of single-axis rotary inertial navigation system to provide a theoretical reference.
