HRG development

TVG - 3

Hemispherical resonator gyro TVG - 3

The TVG-3 hemispherical resonator gyro is designed for operation in strapdown inertial navigation systems (BINS) for civil purpose as integrating gyro.

The principle of operation is based on the lag effect of sanding wave excited in hemispherical resonator.

Inertial measurement unit IMU-HRG

Inertial measurement unit IMU-HRG provides definition and conclusion increments of apparent velocity and angle of rotation (in the form of projections on the axis associated with the block of the sensing element coordinate system).

IMU-HRG designed for use in the systems of orientation and stabilization, navigation systems, cursortype.



IMU-HRG developed on the basis of domestic electronic components.
In the IMU-HRG applied hemispherical resonator gyroscopes, possessing advantages:
  • low sensitivity to external vibration and linear loads;
  • high radiation resistance;
  • low noise component of the measurement.
