A single axis rotary platform is distinguished among the laboratory equipment for testing gyroscopic devices and systems and their sensitive elements. An overview of the design principles of industrially developed stands for the study of static and dynamic characteristics of gyroscopic devices and systems is provided. The scheme of design of the universal laboratory stand is suggested as the compact rotary platform for research of static and dynamic characteristics of micromechanical gyroscopes and accelerometers as sensors of angular speed. The physical components of such a stand and technical and technological problems of its practical implementation are reviewed. The proposed laboratory stand is considered as a cyberphysical system where computing components play a crucial role in determining the parameters of the system and the studied micromechanical sensors. For this purpose, in addition to the physical control loop of the electric drive to ensure the stability of the angular velocity of the platform, an independent measuring loop is considered for analytical determination of system parameters, including the studied micromechanical sensors. The versatility of the stand is ensured by solving the inverse problems, namely determining in the process of testing static and dynamic characteristics of the electric drive and measuring sensors that work on various physical principles. It is assumed that, in addition to solving practical problems of micromechanical sensors in the development of the appropriate information interface of the virtual device, a compact laboratory stand can be effectively used in the educational process during laboratory work in relevant disciplines of instrument making direction.

Orientation and navigation systems increasingly use gyroscopes with internal elastic gimbal, due to their advantages in comparison with traditional gyroscopes: small mass-size characteristics, absence of dry friction, high enough accuracy. It is necessary to research not only static but also dynamic characteristics of gyroscope as an important link of this automatic control system, in order to ensure the functionality and to get the best characteristics of gyroscope systems in the process of operation. All this requires a detailed study of design and technological factors influence on the dynamic accuracy of the gyroscope, as well as the system as a whole. The paper deals with two-component angular rate sensor based on a gyroscope with an internal elastic gimbal. The design and technological factors determining the dynamic accuracy of this type of gyroscope are investigated. The numerical evaluation of each considered factor influence on the accuracy of the two-component device is given. A variant of compensation of the angle sensors inaccuracy influence and torque sensors influence on the dynamic accuracy of gyroscope is proposed and its efficiency is numerically evaluated
