METHOD OF ANGULAR VELOCITY MEASUREMENT USING A SOLID-STATE WAVE GYROSCOPE Russian patent published in 2020 - IPC G01C21/00 

FIELD: instrument engineering.

SUBSTANCE: to increase accuracy of angular velocity measurement by means of wave solid-state gyroscope its body is stabilized in inertial space by angle of rotation around axis of sensitivity, for this purpose gyroscope is arranged on platform of gyrostabilizer as gyro sensor with axis of sensitivity parallel to gyrostabilizer axis, on which gyrostabilizer housing angular speed sensor is installed relative to its platform, then the gyrostabilizer is placed on the base fixed relative to the Earth, the gyrostabilizer with the wave solid-state gyroscope is actuated and the elastic wave is brought into the specified angular positions in the resonator, for which stabilization amplifier input is supplied with setting signal by setting elastic wave at different angles, which are measured by system of generating angular position of elastic wave in resonator, as well as angles of the base of the gyrostabilizer are determined by these angles using an angular velocity sensor located on the axis of the platform stabilizer, based on which the angular position of the elastic wave in the resonator and the corresponding setting signal are found, at which the variable component of the wave solid-state gyroscope drift speed is minimum, then in the operating mode the elastic wave in the resonator on the coal is located, which minimizes the variable drift speed, for which stabilizer amplifier is supplied with previously found setpoint signal, and angular velocity is measured along axis of sensitivity of wave solid-state gyroscope, using readings of angular velocity sensor installed on axis of stabilized platform.

EFFECT: invention can be used to increase accuracy of measuring angular velocity using a wave solid-state gyroscope as part of inertial orientation and navigation systems.
