| Abstract: | Because of the increasing accuracy of the satellite attitude control, the requirement for output accuracy and control error for inertial products is also demanding. A global time management scheme for hemispherical resonator gyroscope unit is proposed. The timestamp is added to the data generation of gyro. This method can effectively reduce and quantify the time delay error between the output increment from hemispherical resonator gyroscope unit and the control system, and improve the angular speed accuracy of the superior system. |
