FIELD: instrumentation.
SUBSTANCE: invention can be used in the construction of single-axis and three-axis sensors of angular velocities and linear accelerations for inertial navigation systems and flight control systems for moving objects. The essence of the invention is as follows: the micromechanical vibrating ring gyroscope contains, a permanent magnet magnetic system, a vibrating structure located in the magnetic field of a permanent magnet and a drive system configured to cause the vibrating structure to oscillate at a resonant frequency and a measuring circuit designed to detect movement in the vibrating structure, an excitation control circuit and compensation block. At the same time, the compensation unit is configured to output a scale factor correction based on the signal from the drive system and the stored reference value.
EFFECT: improved accuracy characteristics of gyroscopic sensors.
