The article discusses the features of determining the torque sensor scale factors of dy-
namically tuned gyroscopes on the automated turntable based on a uniaxial gyrostabi-
lizer. Unlike conventional turntables, where very precise values of rotation speed are set
and maintained by means of precision electromechanical systems, in the gyrostabilizer
the turntable platform monitors the position of the controlled gyroscope. Such turntable
has a simple structure, light weight, small dimensions, low energy consumption and cost.
The mathematical model of the gyroscope-gyrostabilizer system is developed and its mo-
tion is studied in transient and steady-state regimes. Software Simulink (Matlab) was
used for numerical simulation of gyroscope calibration process. The effect of the parame-
ters of the measuring system including rotation angle sensors, devices for measuring the
time of the turntable turn and the currents in the moment sensors on the calibration accu-
racy is shown. The influence of the Earth's own rotation speed is determined.
Keywords:
