BIAXIAL INDICATOR GYROSTABILIZER Russian patent published in 2023 - IPC G01C19/00 

FIELD: gyroscopic technology.

SUBSTANCE: invention relates specifically to biaxial indicator gyrostabilizers on micromechanical gyroscopes operating on manned and unmanned aerial vehicles (AV). The biaxial indicator gyrostabilizer contains an outer frame mounted on the base with rotation relative to the axis parallel to the longitudinal axis of the aircraft and a platform located in it, rotating relative to the axis perpendicular to the axis of rotation of the outer frame, with the first moment sensor mounted on the axis of rotation of the outer frame. The gyro stabilizer also contains the first power amplifier, corrective filters, adders, two micromechanical angular velocity sensors, two micromechanical accelerometers, the second moment sensor, two command signal sensors, an optoelectronic sensor, a control device, outer frame channel and platform channel computing devices. Additionally, corrective filters and computing units of computing devices of the outer frame channel and the platform channel are introduced into the gyrostabilizer, due to which the first-order astatism of the platform channel stabilization loop is ensured with respect to the disturbing moment while maintaining sufficient stability margins.

EFFECT: increase in the accuracy of the functioning of the biaxial indicator gyrostabilizer.
