Evaluation of the Experiment Factors Influence in Studying Dynamic Error of the TwoComponent Angular Rate Sensor

Angular rate sensors are widely used in various technology areas, especially in aviation and rocket technologies. Angular rate sensors are installed in aircraft stabilization, orientation and navigation systems to determine the object angular position and control. In addition, they could be introduced in the automatic control systems of a moving object to enter a signal proportional to the angular rate in the control function or to damp the object oscillations occurring under the action of angular or linear overloads. Various design schemes of angular rate sensors are currently known to perform their functionality with required accuracy in the given frequency range. For them, the influence of design parameters and feedback loop on the accuracy of a device under conditions of dynamic operational influences was studied sufficiently. Biaxial angular rate sensor built on the basis of a dynamically tuned gyroscope was considered, and the influence of various design and technological factors on the experimental estimated accuracy of its dynamic error was studied. Main probable factors leading to inaccuracies in determining this error in testing on the angular oscillations bench were considered
