船用静电陀螺导航仪误差分析

Error analysis of marine electrostatic suspended gyro navigator

通过加扰动的方法详细地推导了空间稳定平台结构配置方案的船用静电陀螺导航仪在惯性坐标系的误差方程,即位置误差方程和速度误差方程,并以开环的方式将它们变换为地理坐标系的位置和速度误差.

Error equations in the inertial coordinate system of marine ESGN with space-stable platform solution are deduced in detail by adding disturbance to its navigation equations. The error equations are position error equations and velocity error equations. Then the error equations in the inertial coordinate system are transferred to yield position and velocity errors in the geographical coordinate system in the way of open loop.
