Abstract : the attitude error performance of electrostatic gyro should be understood and the relevant error equations must be set up in order to ensure the navigation precision of esgm . the relation between the navigation errors and the attitude errors of gyro was derived by use of spherical triangle . the simulation results show that the temporal performances of the longitudinal and distance errors which come from the initial alignment errors are periodically variational . they also show that the longitudinal and distance errors resulted from gyro drifts are not convergent in time . thus, the effects of initial alignment errors and gyro drifts can not be neglected and must be estimated and compensated 文摘:为了保证静电监控器的导航定位精度,需要了解静电陀螺的姿态误差特性,建立相应的误差方程.本文采用球面三角形原理推导了导航定位误差与陀螺姿态误差的关系式.仿真结果表明,由初始定向误差引起的经度误差和距离误差的时间特性是周期变化的;由陀螺漂移引起的经度误差和距离误差是随时间发散的.因此,初始定向误差和陀螺漂移的影响不能忽略,必须对其进行估计和补偿
