  2. 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:為了保證靜電監控器的導航定位精度，需要了解靜電陀螺的姿態誤差特性，建立相應的誤差方程.本文採用球面三角形原理推導了導航定位誤差與陀螺姿態誤差的關系式.模擬結果表明，由初始定向誤差引起的經度誤差和距離誤差的時間特性是周期變化的；由陀螺漂移引起的經度誤差和距離誤差是隨時間發散的.因此，初始定向誤差和陀螺漂移的影響不能忽略，必須對其進行估計和補償
