longitudinal attitude
1.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.
