Abstract: FIELD: physics. 
     SUBSTANCE: invention relates to gyroscopic equipment, and more specifically to biaxial indicator gyrostabilizers on micromechanical gyroscopes operating on manned and unmanned aerial vehicles (AC). Biaxial indicator gyrostabilizer (GS) comprises an external frame mounted on a base with rotation relative to an axis parallel to the longitudinal axis of the aircraft and located in it platform rotating relative to axis perpendicular to axis of rotation of outer frame, installed on axis of rotation of outer frame first torque sensor, input of which is connected to output of first power amplifier, input of which is connected to output of third correcting filter, input of the third equalizing filter is connected to the output of the first equalizing filter, the input of the first equalizing filter is connected to the output of the first adder, the first input of which is connected to the output of the first micromechanical sensor of angular velocity installed on the platform with the axis of sensitivity parallel to the axis of rotation of the external frame of the biaxial indicator GS. Installed on the axis of rotation of the inner frame is a second torque sensor, the input of which is connected to the output of the second power amplifier, the input of which is connected to the output of the fourth correcting filter, input of which is connected to the output of the second correcting filter, the input of the second correcting filter is connected to the output of the second adder, which first input is connected to the output of the second micromechanical angular velocity sensor installed on the platform with the axis of sensitivity parallel to the axis of rotation of the platform of the two-axis indicator GS, first micromechanical accelerometer mounted on a platform with a sensitivity axis parallel to the axis of rotation of the platform of the biaxial indicator GS, the output of which is connected to the input of the first amplifier, the output of the first amplifier is connected to the second input of the first adder. Second micromechanical accelerometer is installed on the platform with the axis of sensitivity parallel to the axis of the external frame of the biaxial indicator GS, the output of which is connected to the input of the second amplifier, the output of the second amplifier is connected to the second input of the second adder. First command signals angle sensor, installed on the axis of the external frame of the biaxial indicator GS, the output of which is connected to the first input of the third adder, the second command signal angle sensor installed on the axis of the platform of the biaxial display GS, the output of which is connected to the first input of the fourth adder. Optoelectronic sensor mounted on the platform, the optical axis of which is perpendicular to the plane of the GS platform, the first control device, the output of which is connected to the input of the outer frame channel computing device (OFCCD), and is also connected to the third input of the first adder, the output of the OFCCD is connected to the second input of the third adder, the second control device, the output of which is connected to the input of the platform channel computing device (PCCD), and is also connected to the third input of the second adder, the output of the PCCD is connected to the second input of the fourth adder. 
     EFFECT: higher accuracy of the biaxial indicator gyrostabilizer operation.
